Grasso 5HP Reciprocating compressors for CO2 freezing and NH3 heat pump applications CO2 (Freezing) Since the introduction in 2006 the 50 bar Grasso 5HP compressor, developed for use in CO2 cascade freezing systems, is a well accepted and reliable appearance in the industrial refrigeration market. 4 single stage models from 3 up to 6 cylinders cover a wide range capacities. The extremely low volume ow in relation with the cooling capacity makes this series to a big performer. NH3 (Heat pump applications) A logic further development of the Grasso 5HP series is the integration in NH3 heat pump systems. The 50 bar design makes it possible to condensate up to 82 oC and as a result of that produce high level of water temperatures. Heat pump systems are developing very quick in various segments of industry (Dairy, slaugtherhouses etc.) and contribute in reducing waste heat as well as CO2 emissions Features of Grasso 5HP series ° Compact nodular cast iron compressor housing ° High stage design pressure: 50 bar ° Up to 30 pressure dierence (Pc - Po) models ° Heavy duty axial roller bearing ° Special design gas tight shaft seal ° Counter pressure independed overow valve ° Capacity control steps per cylinder ° Suitable for speed control (500 - 1500 min.-1) ° Peek technology for high eciency and long valve life time
