CALORPLAST plastic immersion-type heat exchangers are suitable for heating and cooling of concentrated inorganic acids, high-purity media or aggressive and surface-encrusting fluids in tanks. They are important components in i.e the surface technology and the chemical industry.

CALORPLAST plastic immersion-type heat exchangers are assembled from standardized tubular modules and thus allow an optimal adaptation to customers’ specifications. All fittings and support elements will also be designed according to customers’ requirements.
The tube moduls are produced using a patented manufacturing process, ensuring a particularly small loss of pressure while providing high heating/cooling performance.
The modular design allows different flow patterns of the cooling and heating flows.

Each CALORPLAST heat exchanger is calculated and optimized in a computer-aided simulation and you will always get the most reasonably priced and reliable layout.
The heat exchangers are easy to clean with pressurized water, steam or chemicals and so provide a long operating time.

Further details:

– possible materials: PE-RT, PP and PVDF
– permissible working temperatures -30 to +140 °C (depending on the material chosen)
– reliable working pressure 3 to 16 bar (depending on the material chosen and the working temperature)
