Tailor made heat exchangers for all kind of flue gases

Over 15 years of experience over a wide range of applications enables us to develop and optimize tailor made flue gas heat exchangers for all forms of combustion processes and associated fuels. Supply options can be either for complete units with casing and headers supplied as a built up unit or loose coils with supports typically on larger units that are assembled on site. Alternatively we can deliver loose tubes

The choice of heat recovery surface and materials of construction are carefully selected to suit the fuel and the operating conditions. The selection may be plate fin, cast iron, spiral fin or plain tubes.

benefits include:

  • Compact package delivers maximum heat transfer in a minimum space.
  • Tubes are continuously supported over the entire length by the plate fins thus providing a vibration-free design.
  • Our continuous silicone rubber seals at the top and bottom of the tube bundle prevent any mixing of inlet and outlet gas.
  • Integrated moisture separation eliminates the need for an external device.
  • Tubes are easily accessed for inspection and cleaning.
