Hermetically encapsulated fans and compressors

(Hermetically tight compressor)

Here, the impeller and motor are combined in a single casing to eliminate dynamically stressed gaskets between the processing area and surrounding ambience.

(Magnetic coupling compressor)

Compared to conventional machines, the MACOUCO® version offers a high level of environmental friendliness thanks to the design principle on which the magnetic coupling is based.
