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

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

Apart from the kilns we build, our customers can also benefit from our knowledge. In the past weeks, our team offered a training for one of our German customers in which 16 operations and production managers, mechanics and electricians learned about our kilns and were able to ask all the questions they had on their minds. Understanding the kiln operation and all specific features is not only important to keep up with rising safety requirements, but also to have all our customers‘ new employees on board. Such trainings are part of our full service to ensure that our kilns‘ advantages are used to the fullest. Contact us for more information!

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.

Highly efficient German tunnel kiln for fine Egyptian tableware

Keramischer OFENBAU installed and commissioned a state-of-the-art new tunnel kiln for Egyptian German Porcelain Company in Alexandria, Egypt.

Since its foundation 1942 by acclaimed artist Fathy Mahmoud, the Egyptian German Porcelain Company has developed into lifestyle staple. Once a humble earthenware factory in Cairo, in 1986 the porcelain powerhouse has evolved, at the hands of its resilient owner Mr Sayed Fathi Mahmoud, into one of the most significant and modern porcelain manufacturers in the world. Now, EGPC stands tall as one of the most substantial porcelain plants in a single location in the world, with a production of 300,000 pieces, per day. Deeply connected to its Egyptian roots, EGPC stays true to the words behind its initiation: art for millions! Today, with an ever growing production, with double digit annual growth, and with a comprehensively renewed technological infrastructure, the Egyptian German Porcelain company represents one of the porcelain sector’s leading forces and best promises for aesthetic creation, customer satisfaction, and quality delivery.(

Keramischer OFENBAU, for 25 years busy in the field of kiln building for the ceramic industry, combines competence, innovation and reliability. This combination is the reason why Keramischer OFENBAU is one of the internationally leading providers of kiln plants for all kind of ceramics, and why the group of companies with three different international locations writes a success story which has received worldwide attention. The experienced and innovative team at Hildesheim / Germany continuously sets new standards for the sintering of ceramic products, it facilitates the integration of kilns into automated production lines and by implementing new firing technologies, i.e., the firing system EnerViT, it improves the energy efficiency of new and of existing kiln plants significantly.

The supplied tunnel kiln is the second kiln from Keramischer OFENBAU for EGPC and underlines the long-lasting and successful cooperation between the two companies. The new tunnel kiln, 50 m long and with a setting width of 3.2 m, is for biscuit firing high quality tableware, at a temperature of 950”C and an output of approx. 40 to/d. The installation includes a 6 m long dryer, kiln cars and a kiln car transport system. The kiln is equipped with the IBF system, a special firing concept for isostatically pressed tableware in staples, which ensures a high temperature uniformity in the plate staples, so that the tension in the plate bodies is reduced extensively and minimizing significantly the vulnerability to tension during biscuit firing.

The installed EnerViT firing system ensures very low energy consumption, resulting in a figure of far below 600 kcal/kg ware, a fantastic value.

The assembly and commissioning period of this kiln was carried out in spring 2021 under severe conditions due to the Corona pandemic, but nonetheless, completion of the plant was achieved within the given timeline, thanks to the great cooperation with the customer and the Egyptian agent Global Trading. Both were extremely helpful for finding quick solutions for whatever situations occur and took good care of Keramischer OFENBAU team. EGPC’s highly qualified experienced technical team is extremely satisfied with the project at all and with the new kiln in particular which contributes a good share to the company’s ever-growing and energy-efficient production.

Tunnel kiln renovation

Satisfied customer talks about renovation of a 20 years old tunnel kiln

Geberit asked: What does it actually mean when a tunnel kiln – the heart of any ceramic production – has to be shut down for maintenance work?

Extensive maintenance work was needed to ensure the long-term operability of the 112-metre-long tunnel kiln at the ceramics plant in Haldensleben (DE). After a good 20 years in operation, a major overhaul of the tunnel kiln had become necessary.

Roller kiln type eRO electrically heated

We constantly consider the development in many different areas, e.g. the broad field of e-mobility and the battery production necessary for it.

Our decades of comprehensive know-how for kiln concepts contribute to the thermal treatment of cathode powder for Li-Ion batteries. In cooperation with manufacturers in the battery industry and relevant networks (i.e. KLiB), energy-saving and sustainable kiln concepts are further developed and used.

Roller kiln type eRO



As a German manufacturer of kilns for the firing of ceramics Keramischer OFENBAU successfully installed a number of chamber kilns for the firing of hand formers in Malaysia, where most of the manufacturers are located.

The advantages of the kiln concept, made by Keramischer OFENBAU:

  • Kiln working without any rails / tracks / cars
  • Using stacks and forklifters for loading and unloading the hand formers, thus enabling great flexibility for the production process
  • Kiln loading and unloading from two sides >> fast and efficient >> short kiln down times.
  • 3 firing cycles per day are possible.
  • Reduction or oxidizing firing
  • Special kiln design, preventing the kiln from cooling down too much between firing cycles, thus resulting in significantly low energy consumption.
  • Low energy consumption >> reducing the carbon footprint.

Besides handformers, this type of kiln is also suitable for glost firing of chinaware or technical ceramics.

Clean firing process with energy-efficient technology


Our customer Geberit Finland says:

About two thirds of the energy consumption in the production of sanitary ware is accounted for by the firing process, in which cast products are fired to produce finished ceramics. The modernisation of the tunnel kiln with the energy-saving heating system EnerViT by Keramischer OFENBAU will therefore have a significant impact on the energy consumption of the Ekenäs plant and thus on CO2 emissions. The achieved energy savings per year are 2900 MWh. This is equivalent to the annual energy consumption of about 160 single-family homes, i.e. heating 120 m2 single-family homes and providing hot water for the needs of four residents. At the same time, CO2 emissions have been reduced by 650 tonnes per year. The same renovation was carried out on a total of 11 tunnel kilns in seven different Geberit sanitary ware factories.

That’s what our customers say:

A total of eleven kilns in seven ceramics plants have been fitted with the energy-saving EnerViT burner technology of the Keramischer Ofenbau GmbH. By retrofitting the kilns, Geberit was able to achieve energy savings of more than 20% per plant.

Shuttle kiln

With shuttle kilns from Keramischer OFENBAU you can adapt to your production requirements.

Even after countless firing cycles, a customer is still extremely satisfied with the shuttle kiln for high-voltage insulators. The kiln with a setting volume of 61 m³ consumes approx. 25 % less gas than comparable kiln systems. According to the customer’s statement, the kiln still requires almost no maintenance, burner adjustment or similar. The gas consumption, temperature distribution and production results with the high-voltage insulators are extremely good. The fibre lining is also in a very good condition.

Very flexible firing curve design due to the high-tech firing system as well as very good temperature distribution even with difficult setting are outstanding features of this shuttle kiln type, which is available both as „down-draught system“ and „up-draught system“.

Keramischer OFENBAU builds a new tunnel kiln plant in India

Energy efficiency at its best from day one

Keramischer OFENBAU is building a new tunnel kiln plant for the Jaquar Group.

The Jaquar Group is one of the leading producers in India in the premium segment of the sanitary ware sector.

The supplied tunnel kiln, 120 m long and 3.6 m wide for firing high quality sanitary ware, is being built at the Bhachau plant in India. Jaquar is relying on the experienced and innovative competence of Keramischer OFENBAU and is placing the kiln including dryer, kiln car, kiln car transport system and modern process visualisation as well as kiln construction and commissioning completely in the hands of the German company in Hildesheim/Germany. For the assembly the proven cooperation with Keramischer OFENBAU India was chosen.

From day one, saleable sanitary ware is produced in this tunnel kiln. Even heavy and geometrically complex parts can be sold immediately after firing without any rejects. In addition to this high product quality, the kiln stands out for its particularly low energy consumption. For a nominal output of approx. 3.745 kg/h the energy consumption is about 650 kcal/kg ware, a fantastic value.

Jaquar is convinced of the state-of-the kiln technology of the German kiln manufacturer such that they decided still during the project phase directly on the energy-saving conversion of an existing kiln system (third-party brand).
