DH evaporators are two-pass dry evaporators designed for industrial refrigeration and process cooling with evaporating temperatures down to -10 ° C. The DH series allows the use of HFC, HFO and HC refrigerants at medium to high pressures (30 to 45 bar). Power range from 18 to 1,500 kW. Thanks to the two-pass design (U-tube), this series can be supplied in a version that allows full tube bundle pull-out. There is a wide range of materials to choose from, as well as a large selection of certificates for pressure vessels.
