The division GEA Heating & Refrigeration Technologies manufactures products including reciprocating compressors, screw compressors, liquid chillers, heat pumps, valves, fittings, dryers and deaerators.

In the same year, Grasso founded a separate division for refrigeration technology.

The Second World War had taken its toll on the factory, so that Grasso had to cease production of margarine machines.

Step by step, it expanded its product range and services through several acquisitions: in 1993, GEA Heating & Refrigeration Technologies acquired GEA Grenco, a Dutch manufacturer of refrigeration technology for the food and shipping industries, and one year later the compressor specialist Kühlautomat Berlin GmbH (KAB, formerly VEB Kühlautomat Berlin).

In the following years until the GEA Group's reorganization in January 2009, the company acquired the current specialist for industrial refrigeration technology FES, Inc. (now GEA FES, Inc.), USA; Morris & Young Ltd, London, UK; the German valve manufacturer AWP (now GEA AWP GmbH).
