DM EVAPORATORS

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

DM is a single-pass dry-expansion evaporator for commercial refrigeration and medium-temperature process-cooling applications with a wide rage of evaporation temperatures (from positive-temperature evaporation down to –40°C). DM is optimised for R134a and R407F refrigerants at medium pressures (21.5 bar) and is suitable for HFO and HC refrigerants. The capacity range is 100 to 800 kW. A wide range of materials is available, alongside a large selection of pressure vessel approvals.
