Caloperm GmbH products

Calodux is the consequent development of totally welded plate heat exchangers combining the advantages of a plate with long thermal length and a totally welded, gasket free heat exchanger. The special corner-less contour of the plate avoids thermal stress, as it might occur in the edge of conventional rectangular plates. The unique design combines the expertise in the field of heat exchange achieved over decades with innovative and extremely flexible application possibilities. From simple water applications to aggressive media, from liquid through gas to liquid-gas-mixtures, Calodux is the answer to complex problems and processes.

Calopyx is a compact, totally welded, gasket-free plate heat exchanger that is suitable for operation with gases, liquids, and liquid gas mixes with phase transitions. The maximum operating pressure is 250 bar. The minimum and maximum temperature is limited by the used material. Calopyx operates in a tmeperature range between -200 °C and 1050 °C. The application range of Calopyx is comparable with shell and tube heat exchangers; however, the risk of fouling is much lower because of high turbulence, even at low flow velocities. The profiled heat exchange plates provide for high heat exchange performance and large heat exchange surfaces at small dimensions. Calopyx achieves a weight and construction volume reduction of up to 85 % while maintaining the same heat exchange rate.

Duopyx is the further development of our totally welded plate heat exchanger and was specifically designed for flooded evaporation. It combines our Calopyx plate heat exchanger with a droplet separator in a single compact unit. The droplet separator is directly integrated in the shell above the plate pack. An additional external pressure vessel is not needed anymore. The hold-up volume and thus the necessary amount of evaporating medium is reduced. Its compact size simplifies handling and minimizes space for installation. Duopyx is used as evaporator and cascade in refrigeration processes as well as in heat pumps. It is suitable for operation with ammonia, CO2 and water but also with all synthetic refrigerants. Duopyx offers all advantages of our Calopyx range.
