The GEA Bock StarCO2mpressor was awarded the  Innovation Label Award 2019 at the Busworld trade fair in Brussels.

The judges picked the GEA's new generation of mobile CO2 compressors for electric bus and railway air conditioning and heating, featuring the innovative "star" drive gear design.
Ulrich Frey, Product Manager Mobile Applications at GEA Bock, said: "We are delighted that our new StarCO2mpressor has received the Innovation Label Award. It confirms the leading position of GEA Bock compressors in the refrigeration and air conditioning technology sector and shows that functionality, economy and climate protection can go hand in hand even with mobile compressors for natural refrigerants." 

At the heart of the StarCO2mpressor is a radial piston technology which is specially designed for transcritical use with CO2 and allowing a compact system design "This makes the new mobile CO2 compressor perfectly suited for space-saving roof installation in electric buses and railways," says  Frey. "This includes the lowest overall height in the industry of only 220 mm and the light weight of only 83 kg, which is at least 25% below the standard compressor in this performance class.”

The StarCO2mpressor is said to be capable of energy-saving heat generation at  outside temperatures down to -20 °C without power-consuming electric or environmentally harmful fuel-operated auxiliary heaters. The manufacturer says this can increase the range of an electric bus by up to 40%.
