RK CO2 transcritical (radial piston compressor)

RK CO2 radial piston compressor (transcritical)

Important Information
- Transcritical CO2 applications are still in the development phase
- They require a completely new kind of system and control
- They are not a general solution for the substitution of F-gases
- Therefore, we would specifically draw your attention to the fact that this information is presented according to our current level of knowledge and may change at any time due to further development. Legal claims regarding the accuracy of the information cannot be made at any time and are thus expressly excluded
- Compressors can only be made available for selected projects
- Operation and warranties are subject to a separate agreement

Special Features
- Simple total construction, aligned to the special requirements in the transcritical sector
- 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 and4 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
