Reciprocating compressors
GEA Grasso 5HP series
Reciprocating compressors for CO₂ freezing and NH₃ heat pump applications.
CO₂ (freezing)
The 50 bar GEA Grasso 5HP compressor has been developed for use in CO₂ cascade freezing systems and 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 of capacities. The extremely low volume flow in relation with the cooling capacity makes this series to a big performer.
NH3 (heat pump applications)
A logic further development of the GEA Grasso 5HP Series is the integration in NH₃ heat pump systems. The 50 bar design makes it possible to condensate up to 80ºC and results in producing high level of water temperatures. Heat pump systems are developing very quickly in various segments of industry (dairy, slaugtherhouses etc.) and contribute in reducing waste heat as well as CO₂ emissions

A new recipe for indulgence
What if your favorite chocolate didn’t require cocoa beans and your coffee was locally produced? As climate disruption, price hikes and ethical concerns hit two of our most beloved indulgences, scientists are reimagining how we produce them – using microbes, not monocultures. The goal: preserve the flavor and properties of coffee and chocolate while minimizing carbon emissions and improving food resilience.
