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.
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%.
