Mobile citybus air-conditioning

Mobile open and Semi-hermetic Compressors

for bus, train air conditioning and transport cooling

The criteria for air conditioning in buses and trains are fundamentally very high and must be strictly observed in the development of ventilation systems. Due to the advancing climate change, electromobility and efficient energy consumption are becoming more and more in focus. A very important point in the air conditioning of buses, trains or in transport cooling is the weight of the cooling application. Here, value is placed on robust lightweights in order not to unnecessarily burden the permissible total weight of a loaded bus. Thanks to decades of development, innovation and engineering experience, the mobile BOCK compressors make their contribution to the environment and ensure a good climate in buses, trains and all transport refrigeration applications.

Semi-hermetic compressors

The HGX34 and HGX22 compressors - developed on the basis of the BOCK gas-cooled semi-hermetic compressor series - have been specially designed for mobile applications in bus and rail air conditioning.

Thanks to the lightweight aluminum construction, the mobile semi-hermetic compressors are the perfect solution for applications where weight is important. Compared to the standard compressor 40% lighter compressors therefore offer system manufacturers better options.

BOCK mobile compressors are available in 2 and 4 pole versions. In the 2-pole version, the speed is doubled compared to the 4-pole versions and the cooling capacity is significantly increased for the same size. The 2-pole compressor HG34 is available in cast iron as well as in aluminum.

Bock StarCO2mpressor HR 40 - naturally innovative!
The innovative "star" engine design of the StarCO2mpressor opens up new possibilities in electric bus and rail air conditioning: space-saving roof installation thanks to the industry's lowest overall height and lightest weight. And energy-saving heat generation without auxiliary heater even at outside temperatures down to -20 °C.

The new CO2 compressor series HGX24 CO2 LT for deep-freezing with high standstill pressures 
High pressures are generally not a special feature in CO2 applications.
However, for an optimum design, the requirements of operating and
of the operating pressure and the upcoming standstill pressure must always be considered. The proven subcritical CO2 compressors from BOCK enable
standstill pressures of up to 40 or 30 bar...
