Cast-iron (DEKA) and glass air preheaters: Design and production

Our products

Air preheaters transfer heat from the flue gases of combustion processes to the air required for the combustion reaction. In doing so, they reduce the quantity of fuel required and thus increase the efficiency of the installation. The result is an optimal utilization of the waste heat. Depending on the desired inlet/outlet temperatures of the flue gases and their composition, a By-Cast air preheater will consist of cast-iron tubes only, glass tubes only, or a hybrid combination

Expected life span

Our DEKA air preheaters are specifically designed to operate in the most demanding conditions (high concentration of particles and/or dust, acid flue gases, etc.). Our R&D department constantly strives to improve By-Cast products to more efficiently meet these challenging requirements. Our long experience in the field, in house testing department, and dedicated high-performing proprietary software are great assets for our engineering. When used under design conditions and/or monitored for deviations from design, our equipment has an expected operational life of well over 20 to 30 years.
