DH EVAPORATORS

Etalase : BITZER HEAT EXCHANGERS AND PRESSURE VESSELS SHELL AND TUBE EVAPORATORS

DH is a two-pass dry-expansion evaporator for commercial refrigeration and process-cooling applications with evaporation temperatures down to –10°C. DH can be used with HFC, HFO and HC refrigerants at medium and high pressures (30 to 45 bar). The capacity range is 18 to 1,500 kW. Thanks to the two-pass (‘U-Tube’) construction, these evaporators can be supplied in the version that allows the extraction of the complete tube bundle.A wide range of materials is available, alongside a large selection of pressure vessel approvals.
