RKX26/31 - CO₂ Compressors - Transcritical

Description

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 with fixed displacement
• Actuator: gas cooled electric motor in 2-/4- pole version (3.000/1.500 rpm)
• Swept volume (m3/h): 2.7 / 5.4
• 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: 68-73 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:

• Only two surface seals on the entire compressor (housing cover, electrical terminal board)
• Pot-shaped, closed housing made of spheroidal cast iron for maximum pressure strength
• Complete power train integrated in the housing, no cylinder cover required
• Only a few small high-pressure compartments
• Valve operation according to the uniflow principle, the suction gas is pushed in one direction through the piston and is thus compressed. There are no alternating gas movements and a minimum amount of gas pulsation
• Centrifugal lubrication with integrated oil separation
• Excellent operating characteristics – radial arrangement of six cylinders on one level
• Well dimensioned drive motors, partially suction gas cooled, in 2 and
• 4 pole versions (1.500 and 3.000 1/min)
• Suction and discharge connections using screwed cutting ring joints for steel pipes (without shut-off valves)
• Safety valves for the suction and pressure area
• Electrical connection box to IP65 with Bock MP10 motor protection
