GEA will showcase what it says is the world’s first semi-hermetic compact screw compressor for ammonia at Chillventa.

The CompaX, which was launched at Mostra in March, combines the GEA Grasso M series compressor, a suction gas-cooled electric motor, and an oil separator into a compact package without external wiring.
The compressor's efficiency is said to come from the copper winding in the suction gas-cooled electric motor – unusual for NH3 compressors. This compact ammonia compressor further reduces the risk of leakage and requires no shaft seal.

GEA says the CompaX represents a decisive move forward, paving the way for a natural refrigerant (ammonia) in air conditioning systems. The concept also places more emphasis on efficiency and sustainability.


The unit follows seven years of development and GEA adds that the CompaX is surrounded by heat exchangers that supplement the concept and add another new product to the Blu chiller line. Advantages are said to include the new liquid chiller's low refrigerant charge of only 40-50g per kW cooling capacity, which meets the international demand for "low ammonia content" liquid chillers.

GEA will be at Hall 7, Stand 502 at Chillventa.
