Star CO2mpressor – Advanced CO₂ Compressor Technology
The Star CO2mpressor is an innovative BOCK compressor developed specifically for mobile applications using the natural refrigerant CO₂ (R744). Its unique design combines compact dimensions, low weight and efficient operation, making it particularly suitable for modern electric buses, railway vehicles and other mobile heating and air-conditioning applications.
The concept uses cylinders arranged in a star formation around the crankshaft. This innovative configuration creates an exceptionally compact compressor design while delivering the performance required for demanding mobile CO₂ systems.
Designed for Mobile CO₂ Applications
A major advantage of the Star CO2mpressor is its ability to combine refrigeration, air conditioning and heat pump technology within space-restricted vehicle installations.
When combined with a heat pump, the compressor can help achieve up to 20% higher efficiency. With a height of just 220mm and a weight of 83kg, its compact dimensions make it particularly well suited to roof-mounted installations on electric buses and railway vehicles.
