Langen Feuerungsbau manufactures special fireproof doors for industry and the energy sector
Langen Feuerungsbau GmbH specialises in high-quality fireproof special doors for industry and the energy sector, in particular for combustion plants, power stations, industrial furnaces, exhaust systems, boiler and drying plants as well as waste incineration plants and biogas plants.
We manufacture these inspection doors, inspection ports, access doors, explosion doors and maintenance holes individually according to customer specifications and deliver our products to customers throughout Europe. Here, the fire-resistant doors are used in various industrial sectors, including incineration plants and the energy industry.
Most of our products are available from stock. In the case of custom-made products, for example, we manufacture according to individual customer specifications and dimensions, with or without inspection ports, fireclay boxes, insulating boxes, protective plates, frames, etc.
We offer industrial and commercial customers, customised solutions for a wide range of challenges in the following areas:
Unless otherwise requested, our special doors are made of several types of cast iron for different temperature ranges and can be used up to 500 degrees Celsius as standard.
The casting types are listed in our catalogue with the designations M01 to M19. For higher temperatures up to 1300 degrees Celsius we use heat-resistant cast steel. Our doors are centrally pendulum-mounted, the displacements are mechanically machined and thus provide optimum contact pressure on the seals all around.
Your benefit: Our refractory construction supplies refractory doors for a wide range of industrial challenges and tasks
