Type HMRC semi-hermetic refrigeration compressor is designed according to IEC/EN 60079-0, IEC/EN 60079-1, IEC/EN 60079-2 and IEC/EN 60079-31 standards. The product is certified for installation in Zone 1 and Zone 2 for gas environment, Zone 21 and Zone 22 for dust environment.
Hermetic compressor uses a main shaft together with the electric motor, both of the compressor and motor are assembled in a same enclosure, the enclosure is removable type. Semi-hermetic compressor is generally used for the equipment with big refrigerating capacity. Due to the structure, maintenance or repair could be achieved if breakdown occurs inside of the enclosure. When comparing with hermetic compressor, semi-hermetic compressor has several merits such as low requirement for materials, convenient maintenance and low cost.
