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
