The CALORPLAST thermoplastic gas-liquid heat exchanger is a process device for heat transfer from a gaseous (vapor) medium to a liquid medium.

Manufactured entirely from thermoplastic materials and used for heat recovery, as well as for cooling and heating large gas flows.

Main areas of application are:

– Energy recovery from corrosive exhaust air in the surface finishing, chemical process and electronics industries.
– Cooling and heating of aggressive exhaust gases from fume scrubbers, in drying technologies, chemical and metal processing, waste incineration, sewage sludge incineration, cooling air flows with groundwater, saltwater applications, etc.,
– Ventilation installations in clean-room technology, as well as in plants with high demands for sanitary conditions
– Condensation of vapors in the chemical and pharmaceutical industries and the recovery of solvents in a closed loop drying process.

The product range is based on a modular design and can be used for gas volume flows of up to 90,000 CFM. Optionally the heat exchanger can be equipped with a mist eliminator for use with gases containing entrained droplets or moisture. An internal wash-down system can also be included to allow cleaning of the mist eliminator in place. The gas-tight casing is fabricated from heavy walled thermoplastic sheets and contains a condensate collector, reinforcing ribs and flanges.

Further details:

  • Materials: PE-RT, PP, PVDF
  • Temperature range -22 to 284 °F (depending on the material chosen)
  • Reliable working pressure 45.5 to 232 psi (depending on the material chosen and operating temperature)
  • Optimal contact with the incoming gas flow is achieved by the aerodynamic orientation of the collector tubes in our heat exchanger design.
