Company tour in Hildesheim

📌 Company tour in Hildesheim

Our success worldwide benefits from global partners as well as a strong local network. As the 2023 winner of the Lower Saxony Foreign Trade Award, we have proven our expertise, success and importance.

That’s one of the reasons for yesterday’s visit to our premises in Hildesheim: The city’s Head Mayor Dr. Ingo Meyer and Wolfram Fischer, Head of Economic Development and Real Estate, joined us for a lively exchange on many interesting topics.

company tour

Apart from general interest in our company, our team, our export strategy and processes, we have also dived deep into the latest topics for a strong future. With our expertise, innovations and long-standing focus on efficiency, we are the ideal reference for future-proofing the industry. Alternative heat sources were thus a central talking point: How do we decarbonise via electrification or the use of hydrogen? How can we use these technologies locally? How can we best use local networks for effective exchange, know how, and mutual support? And of course, attracting even more expertise and highly qualified personnel to our city was discussed intensely.

Great conversations, lively exchange, and a positive outlook – thank you for your visit and the interesting talks! The Keramischer OFENBAU team is looking forward to the next visit and company tour!

Home office for office dogs?

❓ Home office for office dogs?

Our team includes not only two-legged colleagues, but of course some four-legged ones as well. This also finds resonance in Germany’s oldest daily newspaper.

Home office for office dogs

We have previously presented our department of office dogs here on LinkedIn as well. Milow, Leo, Merlin and Kira provide cross-departmental support in the areas of motivation, stress management, team spirit and exercise on the job. And as Anne Zumhasch explains in an interview with the Hildesheimer Allgemeine Zeitung: When one of the four-legged staff is on home office duty, it stands out. The question „Who authorized that?“ is then almost a matter of etiquette.

Of course, not only office dogs „work“ at our location in Hildesheim. Especially our teams in export, construction management and commissioning are looking forward to energetic support from new colleagues. And if you would like to become an industrial clerk, you’ve come to the right place.

You can find more information on our careers page. We’re looking forward to getting in contact with you!

Talks for the future

Talks for the future 💡

Our systems are always ahead of the times – our focus has long been on developing particularly energy-efficient and future-proof industrial kilns for our customers. And we are also intensely driving forward the ceramic industry’s gradual move away from fossil fuels.

However, converting existing plants to hydrogen operation with our EnerViT H2 ready requires, in addition to our proven technologies, one thing above all: sufficient hydrogen for production.

This is of course a topic for MP Bernd Westphal as the spokesman for economy and energy policy. So we’re delighted to have had such a constructive exchange on the topic with him here in Hildesheim!

ceramic production with hydrogen

The potential of hydrogen in the ceramics industry is indisputable. To achieve decarbonized production of everyday items such as plates, bricks or sanitary ceramics, we must all work together – for an industry that is fit for the future.

Are you interested in more information about ceramic production with hydrogen – thanks to our EnerViT highly efficient as well? Contact our experts for a personal conversation! Our focus is on the future. Therefore, we not only offer the most efficient industrial kilns running on hydrogen. We also develop the optimal concept for every need. Whether electrically operated ceramic kilns or maximum efficiency – we are the ideal partner for your long-term success.

Summer greetings from Hildesheim

Summer greetings from Hildesheim

The PV system on the roof of our headquarters in Hildesheim is diligently producing the energy we can now gather thanks to great weather. With the temperatures of the last few days, things may be moving a little slower for once, but it’s good to be in our cooler offices. And when vacation weather comes to us, everything is a little more fun 🔅

Summer greetings from Hildesheim

The Keramischer OFENBAU team wishes all partners, customers and interested parties pleasant summer days!

Outside, temperatures climb above 30° C – but in our kilns, of course, it gets even hotter: at up to 1,800° C, sanitary or tableware ceramics, fuel cell components or building ceramics burn there. And highly efficiently of course. Because that’s what we’re particularly good at! More information is available on our LinkedIn profile, here on our website and at . Get in contact!

Summer greetings from Hildesheim!

Hydrogen for the ceramics industry

❓Hydrogen as an option for the ceramics industry?
💡Our take: YES!

We have been aware of it for quite some time: the ceramics industry must find and use alternatives to fossil fuels for the industry’s future and energy transition actions. Both ecological and economical factors make this the only sensible solution. And we see two strong options here: 1️⃣ Electrifying new plants and 2️⃣ alternative gases in existing plants.

Our partner Forschungsinstitut für Glas | Keramik has published their take on hydrogen in the ceramics industry here. And we have also thought about it intesively! Hydrogen for the ceramics industry?

Hydrogen for the ceramics industry

Hydrogen for the ceramics industry?

Electrifying existing kiln plants is rarely a reasonable approach. We see a high potential for the use of (green) hydrogen in these cases. We already offer kilns and modernizations today that are not only highly efficient but allow for the use of up to 💯% already. Save energy and utilize innovation – that’s the ceramic industry’s future!

Transitional solutions are necessary until the industry’s energy needs can be fully met by renewable energy sources – making a defossilization possible. We offer high flexibility in this transition with our EnerViT H2 ready (flexibly using N-gas or hydrogen) as well as with hybrid plants that can even be operated with electricity produced on site.

We need to set the base for a sustainable future now. Find more information on our offer for a decarbonized ceramics industry here and here on our website.

Keramischer OFENBAU in Germany’s oldest daily newspaper

We’re all not always aware of how each and every one of us comes into contact with products from our kilns every day. Whether directly, with a ceramic cup in hand, or indirectly through high-voltage insulators – the probability that a ceramic object comes from one of our kilns is quite high.

And that’s a good thing! After all, we have been writing the goal of the more sustainable kiln of the future on our flags for many years now. Low-threshold through energy modernisation H2 ready or profound through the new construction of highly efficient electric plants – we are actively shaping the ceramics industry.

Foreign Trade Award for Keramischer OFENBAU!

We won the Lower Saxony Foreign Trade Award!

Yesterday, our managing directors Thomas Alten and Dave McGuinness were presented with the Lower Saxony Foreign Trade Award on behalf of our entire team at the H’Up | Hybrid Event Hub at the HANNOVER MESSE.

„With the Foreign trade award, we honour outstanding companies that are extraordinarily successful on international markets despite global crises.“ This is how Minister Olaf Lies explains the award from Lower Saxony’s Ministry of Economy, Transport, Building and Digitalisation.

Being among the three nominees is already an honour in itself – and above all confirmation of our work over the last few years. 10 years ago, we already applied once and were happy to be nominated. But this year we have taken it one step further. Under the motto „Export success despite permanent crisis“ we have „brought the horse to Hildesheim“ this year.

This makes us very proud, especially after the last few years, marked by global crises! Supply chain problems, travel restrictions, wildly fluctuating price levels in many areas… We have not been spared. But thanks to a great team that has faced every challenge with competence, dedication and flexibility, we are stronger today than ever!

Thank you!

We thank you for all the congratulations and would like to congratulate once again ELEA Technology GmbH and Bergmann Maschinenbau GmbH & Co. KG, who secured a nomination and were rewarded for it with fantastic image films! We also congratulate the nominated large companies Voß Edelstahlhandel GmbH & Co.

Nomination Foreign Trade Award 2023

The nominations for the Lower Saxony Foreign Trade Award 2023 have been announced – and we are in!

We are one of three companies nominated for the Lower Saxony Foreign Trade Award 2023 in the SME category! After the challenges we faced in the past years, we are even more delighted that we were able to convince with our philosophy, our story and our successes.

Export success despite permanent crisis“ – this is the motto of this year’s Foreign Trade Day, during which the award will be presented. And this motto describes our path over the last few years: despite, or perhaps because of, travel restrictions, supply chain pressures, inflation, price fluctuations, rising energy costs and other challenges, we have been able to prove ourselves and are now stronger than ever.

Our long-standing focus on energy-efficient kilns is now proving to be spot on; with competence, efficiency and innovation, we are in a very good position. Flexibility, creativity and a great team keep us moving forward, further towards the kiln of the future and a more sustainable ceramic industry.

This is also confirmed by the nomination of the expert jury consisting of representatives of the Investitions- und Förderbank Niedersachsen – NBank, NORD/LB, IHK Hannover, NiedersachsenMetall, the Lower Saxony business associations, the state representation of the Lower Saxony chambers of crafts, AGA Unternehmensverband and Deutsche Messe AG under the chairmanship of State Secretary Frank Doods. Many thanks to all involved!

For our customers – and the future!

Internationally, we convince with customised solutions for every need, highest quality thanks to engineering with experience and expertise, close-knit support and maximum reliability. Investing in a Keramischer OFENBAU plant is therefore always a sustainable investment in the future; it enables maximum quality of ceramic production for years and decades. The quality of our plants and our reliable service – that builds trust. And trusting cooperation is part of our recipe for success. Because what is more convincing than really good work?

We approach kiln systems holistically. That’s why we not only build new efficient plants, but also upgrade existing plants. Thanks to EnerViT, up to 50 % emissions can be saved by halving gas consumption. This generates economical kilns that, with EnerViT H2 ready, are even prepared for the complete elimination of fossil fuels.

Nominated – not the first time!

We were already among the lucky nominees in our last application 10 years ago – what an honour to be included again this year. In 2013, we thought about energy efficiency in every project. That has not changed. In the past decade, we have expanded our team, moved, learned a lot and perfected our product. We have never lost sight of the kiln of the future. Also, we have been able to prove several times how flexible, resilient and creative we are in critical times. We countered travel restrictions with AR glasses, supply chain problems with diversification. Of course, we have continued to digitalise, network, overcome challenges and become stronger.

Nomination Foreign Trade Award

Today, ceramic products are fired in our kilns on five continents in 50 countries. Seven of the top ten producers of sanitary ware use our technology and our great team keeps growing. We can be really proud of this development!

How fantastic that the Lower Saxony Ministry of Economy, Transport, Building and Digitalisation also acknowledges our strengths. We are very much looking forward to the award ceremony on 19 April at the Hannover Messe!

Stay tuned and check our LinkedIn profile for more information!

Our plants are in great demand, so our team really appreciates support. Become part of our success story and apply today!

The kiln of the future

Kiln of the future

Sustainable ceramics production thanks to Keramischer OFENBAU

We are proud to be part of this project on the way to the most efficient and sustainable production of sanitary ceramics. Our customer has the goal of making ceramic production sustainable and thus future-proof. We are the ideal partner in this endeavour!

With our experience and expertise, we have been convincing our customers for maximum energy efficiency with our EnerViT system for more than a decade. However, we do not rest on our laurels of building the most efficient kilns on the market. EnerViT is always one step ahead: with our technology, this customer’s plants are not only particularly energy-efficient, but they are also ready for a conversion to 100 % hydrogen!

We are now building several kilns for the company that are efficient today and will run on hydrogen tomorrow. Because this is what the ceramics industry of the future looks like: Efficient and independent of fossil fuels. With Keramischer OFENBAU, this change is already taking place today.

kiln of the future

We are very much looking forward to the successful cooperation with the RAK Ceramics team! You can read exactly what the project looks like here in our client’s newsletter.

Do you want to make your production sustainable and future-proof? Find more information about our portfolio here or on our LinkedIn profile. Get in contact with us, for example via !

Efficiency – and not only energetic!

Efficient cooperation between Northern Germany and Northern India

Efficiency – the term is not limited to the ever so important energy efficiency for us!

We continuously provide you with insights into our Hildesheim team, but did you know that we work closely with our teams from Keramischer OFENBAU España and Keramischer OFENBAU India?

This allows us to realise projects even more efficiently on site for our customers. Top quality. maximum efficiency, and tailor-made kiln plants – that’s what ceramic producers can expect from us. We build state-of-the-art kilns of highest energy efficiency. And we optimise existing plants for maximum energy savings, depending on our customers‘ needs. With our team in India, our local customers also have a contact person directly at their plant even faster.

We build state-of-the-art kilns with the highest energy efficiency levels and optimise existing plants for maximum energy savings, just as our customers need it. And not just for heating with natural gas – our portfolio ranges from electric heating to operation with 100 % hydrogen. And that for a wide range of applications from tableware, sanitary ware or building ceramics to technical ceramics, fuel cells and battery powder.

A little glimpse of the cooperation between the German and the Indian team: Georg von Oldershausen and Sandeep Mathur on a customer visit and a tunnel kiln resulting from our teamwork in action.

efficient collaboration Germany and India

We rely on excellent partnership and intensive exchange to bring the kiln of the future to the whole world. And successfully so!

Many thanks to our Keramischer OFENBAU India team for the close and successful cooperation!

Then and now

How time flies!

We have rummaged deep in the photo box and found pictures from the founding days of Keramischer OFENBAU. We simply cannot withhold this picture from you. A lot has changed in the last quarter century, but technology especially, as the comparison between then and now clearly demonstrates. Besides, our team has grown significantly, we moved premises, we’ve convinced more and more customers worldwide and, of course, we have evolved as times changed. You can clearly see the contrast here!

time flies

But one thing has not changed: With our kiln systems, we are ahead of the times. State-of-the-art, reliable, adapted to individual requirements and, above all, energy-efficient. Today, this is more convincing than ever!

Eines hat sich aber nicht verändert: Mit unseren Ofenanlagen sind wir der Zeit voraus. Hochmodern, zuverlässig, individuellen Bedarfen angepasst und vor allem energieeffizient. Das überzeugt heute mehr denn je! We are not only the market leader in energy-saving industrial kilns for ceramics, our plants also keep every promise.

On our LinkedIn profile, we introduce ourselves and our products. For example, this roller kiln we built 25 years ago that still reliably fires our customer’s products today. We carry out the modernisations keeping the plants up to date in terms of safety and energy particularly meticulously and efficiently.

Contrast and continuity!

Today, we can continue to offer our customers the best of the best, with many years of experience, always thinking through innovation creatively. That’s why our kiln plants are not only especially efficient, we also build kilns with alternative heating methods. A new electrically heated kiln? The modernisation of an existing kiln for 50 % less gas consumption? Retrofitting our EnerViT system, designed for operation with hydrogen? We are experts for these aims, with a wealth of experience, creativity and the highest level of customer orientation.

More information about us, our products, and our services can be found here or here on our website.
Plus, our top team never says no to reinforcement by new talents. So we look forward to receiving your application for one of our vacancies!

Greetings from Ambiente trade fair

Sales trip: greetings from Ambiente trade fair!

Our salesman Georg von Oldershausen is on the road again. After a joint customer visit with Sandeep Mathur from Keramischer OFENBAU India, he now sends his greetings from the Ambiente trade fair in Frankfurt. Among others, he got to talk to our agent Önder Bozok and Minh Ly, owner of Minh Long I at the fair.

We’re glad that we can travel again and exchange ideas differently and most importantly in person again. Many countries, many faces and one topic: the energy-efficient, state-of-the-art kiln of the future!

Sales trip

A popular topic of interest at the Ambiente: energy efficiency, alternative heating and thus more sustainable production of (tableware) ceramics. We are the ideal partner for this, not only because of our highly efficient EnerViT system. Thanks to EnerViT H2 ready as well. We combine large energy savings at a low threshold with the possibility of replacing emission-intensive natural gas with hydrogen. And this by up to 100 %. More information is available here on our website or via mail at .

You are outgoing and willing to travel, customer-oriented and would like to build the kiln of the future as part of the Keramischer OFENBAU team? Our sales team is looking forward to your support! Find out more about us and your career at Keramischer OFENBAU here.

We’re looking forward to getting in contact with you!

Measures, measures, measures

Measures, meaures, measures for a good energy balance

For a comprehensive energy audit, we need a reliable data basis. Here, our team collects this crucial data in on-site measurements for our customer – with a lot of fun at work, of course!

good energy balance

But why measure before the modernisation of the kiln actually starts?

Such work is particularly important when it comes to optimising the energy efficiency of industrial kilns. How much energy does the plant consume? And how much of it can be saved by installing our EnerViT system for instance? How much waste heat is generated and can thus be put to further use with our heat exchangers? These questions can be answered best on the basis of reliable energy data after careful measurements.

More information on our well-established optimisations of ceramic kilns is available here. Especially our EnerViT system allows for a great potential in energy savings. And we can do even more: With EnerViT H2 ready, your kiln is ready for up to 100 % hydrogen! Feel free to contact us at or visit our LinkedIn profile for more interesting insights.

Our team also welcomes new talent to build the kiln of the future with us. You can find our current job offers and read more about your career at Keramischer OFENBAU here on our website.

Did you know… ?

Did you know… ?

Did you know that we built our first roller kiln 25 years ago? Based on our team’s experience, we have gained a lot of experience, constantly developed, and become the market leader in terms of energy efficiency since then. But we also did convincing work a quarter century ago – after all, this first roller kiln of the Keramischer OFENBAU team is still busy producing flower pots and planters today! Of course, energy and safety modernisations were carried out during this time, imperative for reliable and safe operation.

The early trust in us has more than paid off for our customer. That is why this was not the last Keramischer OFENBAU kiln for this company. Their second roller kiln was installed by our team ten years ago.

Heat exchanger for efficient kiln plants

Effective solution for efficient kiln systems

Getting more out of the energy used – That‘s more important today than ever before, in the ceramic industry as well. That’s why we design and build highly efficient industrial kilns for our customers, tailor-made to meet every need. However, a new plant is not always necessary for maximum efficiency. We can also achieve optimal results through energy-efficient modernisation. And at comparatively little expense, for example by retrofitting with heat exchangers.

Our air-water heat exchangers enable the extensive use of exhaust air from cooling processes in continuous kilns and thus offer particular advantages: Besides easy integration into existing processes, particularly high heat transfer and facilitated insulation, a water-based system allows for additional storage of the recovered energy. Our customers can thus further utilise this thermal energy and thus reduce both energy consumption and emissions.

heat exchangers

A plant modernised in this way not only becomes more efficient, but can additionally be retrofitted and further optimised later with our EnerViT system – ideally even with EnerViT H2 ready.

Get the best out of your system, use your residual energy! Would you like to learn more about our optimisations and their efficiency? Feel free to contact us and visit our LinkedIn profile. Learn more about us and our performances here! You would like to become part of our awesome team? Find our current vacancies as well as information about Keramischer OFENBAU as your employer here!

Energy efficiency with Keramischer OFENBAU

Energy efficiency with KeramischerOFENBAU

Making more out of the energy consumed – that’s more important today than ever before.

We have prioritised energy efficiency for many years. Therefore, we tailor the most efficient industrial kilns for products of the highest quality for every need. With this, we convinced our long-standing customer Turkuaz Seramik, as this interview starting on page 82 in the Ceramic World Review of Tile Edizioni shows.

More output with less consumption – that’s what our EnerViT system achieves in new plants and the optimisation of existing plants. And not only that. EnerViT H2 ready allows a low-threshold conversion to hydrogen as soon as it is available on site. This article in the ceramic world web newsletter on our EnerViT technology provides more information (and of course pictures).

You would like to commission a new kiln that reliably fires your table- or sanitary ware, your technical or structural ceramics exactly according to your needs? Are savings in energy consumption particularly important to you? Then we are your ideal partner! We engineer and build your plant exactly as you need it. Does your kiln system deserve an optimisation or modernisation to achieve the state of the art not only in terms of safety but also of energy? We are experts in this field! We get the maximum out of your system, in every respect.

Energy efficiency with KeramischerOFENBAU

Competence, efficiency and innovation, this mixture is what makes us stand out and we are proud of it! We have convinced our long-standing partner Turkuaz Seramik with this more than once.

Find out more about us and our EnerViT system here on our website or contact us directly with any further questions. We look forward to it!

New partner in Turkey

New partner in the new year!

Did you have a good start into this new year of 2023? We sure did!

The strong order book we have built up over the past year is further complemented by our collaboration with Bartin Seramik. We are not the only ones appreciating this cooperation, the customer is impressed as well, as this LinkedIn post shows. Congratulations on the decision for highest energy efficiency in your new tunnel kiln with our EnerViT system!

Our sales expert Georg von Oldershausen held detailed and in-depth talks with @Gürkan Aldatmaz Bay on our behalf in Turkey to offer the ideal kiln for Alvit and Quarter Bath sanitary ceramics. Once the new kiln is in place, it will combine the best quality with maximum efficiency and minimised energy consumption – a really good mix.

2022 with Keramischer OFENBAU

Our annual review 2022

On the last day of the year, we can now look back on a successful year with ups and downs that we have mastered as the great team we are. You don’t go through uncertain times alone, we know that. That’s why we are all the more grateful for the team spirit we have shown in this busy and successful year!

Our MD Dave McGuinness pointed out at the last staff meeting of the year that „the excellent and steady state of the projects up to 2025 is only possible because of our excellent team.“ What an accomplishment after more than two years under Corona conditions!

MD Thomas Alten takes a similar view: „I really see a first class team here, characterised by competence and great commitment. I would like to emphasise the development we have undergone, even through the crisis. We are now stronger than ever! Therefore, we continue to pass on our knowledge and expertise to new talents.“ And our customers would agree, as regular feedback from our partners shows.

We do our job really well, that’s for sure. „I see our strengths not only in our market leadership in efficiency and reliability, but also in development. And I don’t say this lightly – our customers‘ feedback regularly proves it!“ as Thomas Alten puts it. And what would the team be without the captain, the captain without the team and the company without motivating partners and customers?

annual review

We can thus be proud of ourselves and look forward to next year!
A Happy New Year from the Keramischer OFENBAU team!

Christmas party a little different

Lying under your desk at the office Christmas party? That’s now part of good manners at Keramischer OFENBAU!

We started off our Christmas party with an office golf tournament, prepared and directed by an expert. Although the parcours in our premises in Hildesheim demanded some flexibility from our five teams and their commanders, we successfully worked our way through, accompanied by lots of laughter. Thus, the following Christmas market style food and drinks were well deserved!

After honours and prizes were awarded, the hard core welcomed the new day again – that’s how it should be! What an awesome and fun evening – thanks to the great preparation by Silvi Tono and all the other hard-working helpers. We are looking forward even more to the next company event next year!

Thank you to the entire Keramischer OFENBAU team for this wonderful Christmas party and fantastic finale to the year! Now we can start into a calm Christmas season and continue to enjoy the last days of the year.

You would like to support our team next year? Check out our current vacancies on our careers page and contact us via email at . We are looking forward to your contact! Do you need an expert in office golf? We can highly recommend this one!

We wish you a wonderful Christmas season!

Bikes for the team at Keramischer OFENBAU

Bikes for the Keramischer OFENBAU team!

„Karma points for fitness and the environment“ is how JobRad puts it.

We are very pleased to be able to offer our team all JobRad benefits from now on! Want to get some exercise before and after work? Anne Zumhasch definitely does and thus gets on her bike every day in wind and weather, heat and cold. And she’s not alone: the Keramischer OFENBAU team is all about cycling. And we want to support that. With JobRad, we finance the bikes of our employees and turn them into company bikes, for private use as well. This is not only good for the environment, but also for our health!

Bikes for the team: Anne Zumhasch

Of course, our IT specialist Stephan Niemeyer didn’t miss out on this opportunity and will ride his new e-mountain bike the 50 kilometres to work – in warmer weather at least! Our sales expert Georg von Oldershausen’s daily commute is a little too long for a bike ride, but the combination of train and bike usually works very well for him. And our managing director @Thomas Alten also regularly get into the pedals for the almost 20-kilometre commute to our Hildesheim premises. These are just some examples of committed colleagues taking their bike for commuting regularly or from time to time.

Bikes for the team

Energetic and safety modernisation

Modernisation of kilns for maximum efficiency and highest safety!

Our competent and experienced team does not only build highly efficient, individual and needs-oriented new industrial kilns: In this picture, an existing plant is put back into operation after extensive modernisation works. Low-threshold conversions thus maximise not only the energy efficiency of the kiln, but also its safety for everyone involved.

Our plants are always state-of-the-art in terms of safety technology – an important requirement for the operation of any industrial kiln. In order to meet the ever higher safety standards, inspections or modernisations are necessary from time to time. Especially benficial in this case: the safety-related retrofit was carried out at the same time as an energetic modernisation. Highest efficiency paired with maximum safety – a great mix for the customer company and its employees! 

Our EnerViT system was also able to significantly reduce gas consumption and thus running costs in this plant – despite low-threshold measures. These savings are particularly attractive in times of climate change and rising energy costs.

Would you like to become part of our awesome Keramischer OFENBAU team? Take a look at our job postings or our LinkedIn profile!

There is nothing for you in the advertised positions? Are you studying and would like to write a thesis on the topics of SOFC, hydrogen, energy efficiency or e-heating in the ceramics industry? Would you like to be able to implement your good ideas effectively? Congratulations! We also look forward to hearing from you or receiving your speculative application!

Rising energy prices call for efficient solutions!

We do not only provide our customers with most efficient kilns, but also offer highly effective modernizations for existing plants. Retrofitting our heat exchanger systems for instance allows for the extensive use of exhaust air energy. This energy results from cooling processes in any roller and tunnel kilns. Heat exchangers thus save energy.

Our air-water-heat exchangers allow for specific advantages: Besides their integration into existing processes, their especially high heat transition, and their facilitated isolation, a water based system additionally allows for storage of the recovered energy. This thermal energy can thus be used further, reducing energy consumption and CO2 emissions.

Heat exchangers save energy

Installing our heat exchangers enables fast savings through more intensive energy use. The exhaust air energy from the cooling processes in tunnel and roller kilns is not released unused. It is further utilised and thus reduces the plant’s energy demand. Therefore, the system is not only more efficient, it allows the kiln plant to be retrofitted with our EnerViT technology at a later date. This means that existing systems can be converted at low cost to reduce emissions and consumption in more efficient kilns. Our heat exchangers combined with our EnerViT system get the best out of your kiln plant, reduce consumption and your energy costs.

Use your residual energy! Contact us if you would like to learn more about energy efficiency through our heat exchanger systems. You can also find information here and on our LinkedIn profile!

Leading-Edge Efficiency: EnerViT H2 ready

Leading-Edge Efficiency: A more sustainable future in the ceramics industry depends on highly increased energy efficiency and alternative energy sources. At Keramischer OFENBAU, we provide you with both:

Our well-established EnerViT technology allows for up to 50 % savings in both energy usage and CO2 emissions, as we have shown you in our case studies. These savings are very relevant in the industry’s transition towards a greener future, which is why we consider EnerViT an optimal bridging technology. New kiln plants or retrofitted existing plants – EnerViT is both economically and ecologically sensible.

Leading-Edge Efficiency with EnerViT plus H2 ready

But we do not stop here! The electrification of existing plants requires large investments. We thus pave the way towards the kiln of the future running on green hydrogen. We offer our customers our low-threshold solution: EnerViT H2 ready. With this system, the efficiency of ceramic kiln plants is increased immediately. Simultaneously, the plant is prepared to switch from natural gas to hydrogen with minor adaptations as soon as H2 is available.

The future-oriented leading-edge efficiency of this system therefore allows for savings now and heating alternatives tomorrow.
Developing new technologies to solve tomorrow’s problems is a priority for us today. Learn more about our kilns and about modernisations with Keramischer OFENBAU!

Let us shape our sustainable future now and bring your kiln needs to reality!

Meet our moral support department!

Our office dog team! Today, we would like you to meet the first half of our office dog team: Terra and Milow. With our old lady Terra and the youngest team member Milow, these two represent opposite personalities. In our spacious headquarter premises however, Terra can still find her peace even while Milow romps around the office and outdoor spaces. Thus, if a dog owner does not always make use of the home office option Keramischer OFENBAU offers by arrangement, they do not need to leave their animal companion alone.

EnerViT case study no. 4

ENERGY EFFICIENCY: Another one of our case studies concerning the impact of our Keramischer OFENBAU EnerViT system shows the benefit this technology provides even in existing kiln plants:
By retrofitting this 1988 tunnel kiln with our highly efficient EnerViT system in 2020, our customer can now fire their flowerpots saving 33 % of energy and 1 400 tons of CO2 emissions annually!

These numbers show – especially during the current global developments – that retrofitting existing plants with our EnerViT system is a both economically and ecologically sensible low-threshold bridging technology in many areas of the ceramics industry.

Training for our customers

Training for our customers

Apart from the kilns we build, our customers can also benefit from our knowledge.

Summer greetings from Keramischer OFENBAU!

At ceramitec 2022, we gifted flower seed mixtures to our visitors to celebrate summer and it went down really well with everyone. One of our customers even plans to recreate their break meadow with these flowers that are especially attractive to bees.
In this spirit, we wish all our customers and partners a marvellous and hopefully relaxing summertime!

Keramischer OFENBAU: Our 26th company anniversary

Keramischer OFENBAU celebrated the beginning of the second half of 2022, finally being able to enjoy events with the whole team again.

After a city tour that even taught long-standing Hildesheimers more about their city of roses, the extensive barbecue at the Miara restaurant had to be held inside due to unstable weather conditions. We were still able to enjoy a long and pleasant summer evening at the outdoor terrace together afterwards. We’re glad to finally enjoy such events again and that the weather was playing our cards in the end!
Our newest team member Axel Wiener describes this day best: “The cultural first part of the day allowed me to discover Hildesheim and during the culinary second part, I got to know the great team.“

Thank you to the whole team for this awesome day!

Case study No. 3 for EnerViT

EnerViT plus can – as we demonstrated in previous case studies – increase your kiln’s efficiency considerably. Not only existing kilns can benefit from a retrofit with our technology, but building a new kiln is also economically and ecologically sensible with our EnerViT plus system. As most conversations we had at ceramitec 2022 focused on energy efficiency, we want to provide you with insights into the savings we have realized in past projects. Building a new kiln in replacement for this tunnel kiln with our EnerViT plus technology for example allowed for 44.9% of energy savings and 1320 t less CO2 annually. While increasing the output of sanitaryware by one third, energy needs are minimized considerably.
