The new GEA StarCO2mpressor
GEA says its new StarCO2mpressor, to be launched at  Busworld in Brussels from October 18-23, represents a milestone for mobile CO2 applications.

At the heart of the CO2 compressor, is its innovative "star" drive gear design, based on a radial reciprocating technology specifically designed for transcritical use with the natural refrigerant CO2, and Ulrich Frey, Product Manager Mobile Applications, said: "This opens up new possibilities for use in electric bus and rail air conditioning.''

The star-shaped cylinder arrangement
Based on a star-shaped cylinder arrangement, the StarCO2mpressor is said to offer a compact system design with numerous technical and design innovations. Frey said: "The uniquely low overall height of just 220 mm and the light weight of just 83 kg, which is at least 25% lower than other commercial compressor of this performance class, offer perfect conditions for space-saving roof installation in electric buses and railways.''
GEA adds that he welded steel housing and high-performance oil pump make the compressor robust, with minimised leakage potential.  A wide speed range means it meets the power requirements of heat pumps from 12.5 Hz to 75 Hz (750 rpm to 4500 rpm). Further advantages are said to be a high degree of smoothness due to multiple bearings and a safe operation  at high angles of inclination.

Frey said: "Its practical suitability has been proven in advance  in extensive field tests with renowned manufacturers."

  • GEA will be at Booth 163 in Hall 1 at Busworld.
