Hermetic Sealed Unit: 1. The present invention relates particularly to fractional horsepower hermetic refrigerant compressors of the low side type, that is of the type in which the hermetic casing is filled with refrigerant gas at suction pressures. The capacity is determined by the mass flow rate of refrigerant, which depends on the compressor’s displacement, RPM, and volumetric efficiency. As in the case of the accessible-hermetic motor-compressor an electric motor is mounted directly on the compressor crankshaft, but the body is a formed metal shell hermetically sealed by welding. Some are designed with service valves, many have piping stubs and must be braized in place. Product added to the quote request list. Vibration: 3,3 m/s2.
