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.(www.egyptianporcelain.com).
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.

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.
Or have a look at LinkedIn:
Keramischer OFENBAU built two 90m tunnel kilns for the energy efficient production of sanitaryware in Mexico.
The responsible plant manager at site reported about a visit by the headquarters’ kiln specialist, his comments after they had checked thoroughly one of the tunnel kilns:
· It’s by far the most efficient tunnel kiln in the whole group!
· The results exceed by far the expectations!
· The kiln is the easiest one to control and adjust in the whole group!
· The kiln is now approved by the group and the head office strongly recommends to continue working with Keramischer OFENBAU!
· With the two new tunnel kilns they are having a huge capacity.
The customer is open to share private opinion about the great kiln performance in Mexico.
Together with our partner in Mexico Hornos STI, which carried out the assembly of the tunnel kilns, Keramischer OFENBAU are proud of having installed the kilns and working together with this esteemed customer.
The company owner is very satisfied with the two shuttle kilns made by Keramischer OFENBAU, especially that the energy consumption has been reduced by about 50% and that the degree of good ware has been increased considerably by using pre-programmed O2 and temperature curves. The enthusiastic owner also likes the fact that he and his production manager have direct access to the kiln control of the individual kilns with their mobile phones. The kilns were able to reduce a considerable part of the production costs.
The satisfied insulator manufacturer therefore said that with the two shuttle kilns from Keramischer OFENBAU he is well prepared for the increasingly difficult world market.
Congratulations to our trainees Julia and Alina!
They have successfully completed their training as industrial clerks at the end of July 2020.
The two young women have passed through all departments in the commercial and administrative areas of our internationally active kiln building company and have been strongly involved in the practical side of their daily tasks from day one. With their friendly, open-minded and committed manner, they have given important impulses in various areas in a future-oriented manner. Alina and Julia also mastered the special requirements during the Corona Pandemic in the vocational school and especially during the final examinations with confidence and success. Now they are well prepared for a professional life with an international environment.
We thank Alina and Julia very much for the good cooperation, you are great colleagues! All the best, luck and success for everything that comes now.
Congratulations to Keramischer OFENBAU India for the successful assembly of a tunnel kiln for sanitaryware at customer BAFIT, India. Such a great team with a great spirit.
Keramischer OFENBAU India is the No. 1 and market leader for building kilns for the ceramic industry in India and we are very proud of our successfull JV partner. Just have a look at their Puja ceremonies at customer site upon completion of the tunnel kiln assembly. @ Keramischer OFENBAU India: You’re a great team.
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.
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.

#Energyefficiency during thermal treatment in the ceramics industry. The #EnerViT heating system by Keramischer OFENBAU GmbH reduces gas consumption and CO2 emissions by up to 40%, in #kiln plants all over the world. And we are continuously working on innovation with focus on even more #energysavings.
#greenworld: reduce your #carbonfootprint!
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.
Vision for Keramischer OFENBAU and Jaquar & Company Private Limited: a real success story about an energy saving tunnel kiln for sanitaryware, equipped with the EnerViT heating system. Have a look at page 6/7 of Asian Ceramics:
for the procss engineering comissioning of the kiln plants, transport systems and their control systems at customers’ site worldwide
That’s what our customers say:
SAVING ENERGY WITH NEW BURNER TECHNOLOGY EnerViT – made by Keramischer OFENBAU
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.
Retrofitting kilns of any kind
with Keramischer OFENBAU
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”.
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).
