Since the 1990s, we have been manufacturing gas-water heat exchangers in tube bundle design, which have been specially developed for the use of industrial flue and process gas heat at temperatures below 300 °C. With over 250 successful references and state-of-the-art design solutions, our heat exchangers stand for maximum durability and efficiency.

Our gas-water heat exchangers are used in industrial plants downstream of combustion processes with gas volume flows of up to 2,000,000 Nm³/h. They are frequently used in flue gas ducts of power plants (coal, oil, biomass), waste and sewage sludge incineration plants as well as in refineries, smelting works and building materials plants.

There are two basic types:

1. Exhaust gas coolers extract heat from gas flows and make it available as process, district or drying heat.
2. Exhaust gas reheaters heat flue gases to prevent corrosion, aerosol precipitation or vapor plumes.

With our gas-water heat exchangers, we offer highly cost-effective solutions for heat recovery. By using flue gas heat below the acid dew point, maximum energy yield is achieved, resulting in considerable savings in fuel consumption, water consumption and CO₂ emissions.

Thanks to robust corrosion protection based on proven materials such as stainless steel, nickel-based alloys or innovative fluoroplastics (e.g. AlWaFlon® or PFA), our heat exchangers guarantee exceptional durability and reliability, even under extreme conditions.
