Vehicle compressors for mobile cooling - FK series

• Wear-resistant and durable power unit
• Forged aluminium connecting rods for maximum stability and robustness
• Two easily visible sight glasses
• Integrated oil collection system with large storage volume
• Special valve plate systems for bus and transport cooling
• Demand-oriented capacity regulation possible
• Product range with 2-, 4- and 6-cylinder reciprocating compressors
• Ribbed surface optimizing heat dissipation

With the most powerful version FK40/755, we offer customers 15 % more power with the same external dimensions. BOCK® vehicle compressors are equipped with the K valve plate system as standard.

They are ideally suited for bus air conditioning with increased cooling power requirements in city-, intercity and articulated buses or in areas with very warm ambient temperatures.

Unique FK valve plate system specially developed for air- conditioning

• Valve plate made of aluminium
• Working valves made of high-quality, impact-resistant spring steel
• Extremely robust and reliable in the face of speed and pressure fluctuations as well as exposure to liquids
• Long service life due to loosely guided annular discs which prevent bending and torsional forces
• Highest operational safety and efficiency
  
  

For air conditioning and normal cooling.

• For universal use in mobile applications
• Lamellas clamped on one side, which are exposed to bending and torsional forces; therefore limited load-bearing capacity at high speed and exposure to liquids
  

• Specially adapted version for low temperature cooling
• Valve plate TK design for low evaporating temperatures, based on the N-valve plate basic concept with torsionally stiff lamellas
• With additional measures for delivery rate optimization at low evaporating temperatures
• Piston crowns provided with grooves in the suction lamella contour: for further damage space minimization and increased performance in the low-temperature range
• Increased efficiency and performance in the low temperature cooling range

Special K1 housing – Applications for Euro 6

Due to special requirements by customers, there is a demand for additional fastening options on the compressor housing – particularly where there is little installation space available, as is the case in many Euro 6 buses. This has been achieved by means of the K1 special housing, which creates a higher level of stability thanks to the compressor being fastened directly to the vehicle motor.

Special features of the K1 housing:

• Optimized housing
• With intermediate flange 46 mm for suction and pressure shut-off valve
• Available models FKX40/470 K1, 560 K1, 655 K1 and 755 K1
• 6-cylinder compressor series FK50 with K1 housing with additional mounting points on request
