We are offering here the Semi Hermetic Compressor that is the modification of hermetically sealed compressor. Instead of welded steel shell, top cover is bolted to compressor housing. The compressor uses a large cast-iron casing secured with screws which can be opened to repair or replace motor and compressor components. Semi Hermetic Compressor raises gas pressure and transport the gas through a piping system for system distribution needs. Gas rushes through a suction valve inlet and into the low pressure area.
