Thanks to their proven design and constant innovation, the mobile aluminum Danfoss BOCK® compressors make an important contribution to environmental protection and ensure a good climate in buses and trains as well as in transport cooling.
Today, air conditioning systems for buses and trains are required to provide optimum comfort for drivers and passengers. The highest possible energy efficiency for the vehicle and the best environmental compatibility are priorities. The focus is on heating the vehicles using environmentally friendly and emission-free heat pumps. The weight of the refrigeration system is important for the air conditioning of buses, trains or in transport cooling.
When it comes to compressors, emphasis is placed on robust and smooth-running lightweights that also make a decisive contribution to increasing the efficiency of the overall system.
Efficient thermal management of buses and trains
CO2 and low-GWP refrigerants
Energy-efficient, light-weight, and robust
Smooth-running operation and unmatched reliability
