GEA CompaXThe world’s first semi-hermetic compact NH3 screw compressor

Simplified for air conditioning with NH3GEA CompaX is the world’s first semi-hermetic compact ammonia

screw compressor. Its smart three-in-one design with integrated

oil separator and electric motor is particularly suited for use in

modern centralized air conditioning systems, e.g. for office build-

ings, shopping malls, or airports.

A major innovation achieved with the GEA CompaX compressor is

the special motor concept: For the first time it has become possible

to provide a compact ammonia compressor with minimal risk of

leakage, without shaft seal and without additional water circuit or

piping. This simplifies the use of the GEA CompaX screw

compressor for sensitive air conditioning systems and ensures

compliance with demanding safety standards. In addition, the

natural refrigerant ammonia prevents the greenhouse effect and

helps to protect the environment.

Thanks to GEA CompaX you can simply have it all: A minimized

leakage risk for safe air conditioning as well as an ammonia solu-

tion for maximum plant efficiency and a clean environment.
