Semi-hermetic refrigeration compressor M

screwCO2 (R744)ammonia (R717)

GEA Grasso M compressors are the first screw compressors with an integrated pressure-activated check valve ensuring low pressure drop. The integration of the suction filter and coupling housing greatly simplify assembly of the package. The outstanding energy-efficiency of these compressors is based on the infinitely adjustable capacity combined with the extended variable Vi-range (internal volume ratio). The variable speed from 1,000 to 6,000 rpm ensures a wide operation range and maximum efficiency in full and part load. Highlights & Technical Features Outstanding energy-efficiency Easy package assembly Designed for ammonia (R717) and all other common refrigerants Available according to API 619 and ISO 10440 standard Swept volume: 231 – 870 m³/h at 2,940 rpm Speed range: 1,000 - 6,000 rpm Design pressure: 28 bar, 52 bar
