The corrosion-resistant Colasit heat exchangers made of plastic enable efficient recovery of energy from aggressive gases. Our plastic heat exchangers have a high degree of chemical resistance and easy handling during cleaning. Furthermore, all EU directives concerning energy efficiency are met, and thanks to the low-pressure loss and energy recovery, they are also economically viable.

Colasit heat exchangers have a modular design and enable individual single solutions to be manufactured.

Gas-water heat exchanger made of plastic for energy recovery - Colasit



  • During heat recovery from corrosive exhaust air and gases, e.g., in electroplating, the chemical industry, the electronics industry
  • When cooling corrosive waste gases from scrubbers and heating up subsequently, e.g., in drying technology, during chemical metalworking, waste incineration, sewage sludge incineration, etc.
  • As a capacitor for vapours in the chemical, pharmaceutical, drying technology industries, etc.
