Mobile citybus air-conditioning

Mobile open and Semi-hermetic Compressors

for bus, train air conditioning and 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.

Thanks to their proven design and constant innovation, the mobile aluminum compressors from BOCK make an important contribution to environmental protection and ensure a good climate in buses and trains as well as in transport cooling.

SEMI-HERMETIC COMPRESSORS FOR MOBILE USE

LIGHTWEIGHT ALUMINUM CONSTRUCTION

Semi-hermetic compressors

The all-aluminum lightweight design of the HGX34 and HGX22 compressors compressors is ideal for mobile refrigeration and air conditioning applications. Compressor weight and compressor efficiency are critical. Thanks to the lightweight aluminum design, the mobile semi-hermetic compressors are 40% lighter than the standard compressor. System manufacturers in the field of bus-/railway air- conditioning and transport cooling are thus offered new possibilities.

BOCK mobile compressors are available in 2 and 4 pole versions. The 2-pole version of the HG34 offers a significant increase in performance with identical dimensions.

The compressors are available with a terminal box in reduced height and are more compact than the standard version. BOCK mobile aluminum compressors meet the highest fire protection class HL3 of EN45545 for railroad applications.
