SED-20LFJ-H — Dryer - Freeze-Drying Auxiliary Equipment

Compressor draws low-temperature, low-pressure refrigerant vapour from the evaporator and compresses it to high-temperature, high-pressure gas, which is sent to the air-cooled condenser where ambient air removes heat and the refrigerant condenses to liquid. After passing through the externally-balanced thermal expansion valve, pressure drops sharply; the low-temperature liquid refrigerant enters the evaporator and absorbs heat from the process air stream (cooling it). The resulting vapour is again drawn into the compressor, forming a continuous refrigeration cycle.
