Bock has developed a complete semihermetic, electrical driven compressor-series for transcritical R744 applications like industrial and commercial refrigeration or air-conditioning.
Basic specifications
• Type of Construction: semihermetic radial piston compressor, fixed displacement
• Actuator: gas cooled electric motor in 2-/4- pole version (3.000/1.500 rpm)
• Swept volume: 31ccm
• Displacement volume: 2,60 m³/h - 6,70 m³/h
• Number of cylinders: 6
• Maximum speed of rotation: 3600 rpm
• Compressor Diameter x Length: 205 x 440 mm
• Overal Weight: 73 kg
• Oil: Bock C120E (Synthetic Oil)
• Oil Separator: integrated
• HP and LP savety valves
• Motor winding protection with PTC sensors and Bock Motor protection Unit MP10
• Terminal Box IP65
Advantages:
• Simple & reliable mechanism, especially designed for transcritical R744 application
• Very small dimensions through the cylinders' circular arrangement on one level
• Universal scope of mounting positions (horizontal and vertical)
• Only 2 gaskets on the entire compressor
• Closed housing, made of spheroidal graphite Iron for maximum pressure resistance • Complete power train integrated in the housing, no cylinder covers required
• Minimum gas pulsations, enabled by parallel flow valve principle
• There are no alternating gas movements
• Integrated oil management including oil separator for reduced OCR
