HASEGAWA VM*2 RM Compound Compressor and Spare Parts

VM*2RM compressors should not be operated beyond the following limits:

Compressor RPM: Max. = ***0 rpm (VM =***0rpm) Min. = **0 rpm
Compression ratio* Max. = *5 Target Max: R**7 *0, R*2 *1
Pressure difference Max. = **7 psi (*6.*7 kg/cm″) [1.6MPa]

Suction pressure, Two stage compressors:
Max. *8 psig (C.S.T: R**7 = *4°F, R*2 = 5°F)
Max. 0.2 MPaG (C.S.T: R**7 = **0°C, R*2 = **5°C)
Min. *1 psig (C.S.T: R**7 = **6°F, R*2 = **4°F)
Min. *0.*8MPaG (C.S.T: R**7 = **0°C, R*2 = **0°C)
RM type compressor
Max. Determined by motor capacity.
Min. *1 psig (C.S.T: R*2 = **4°F)
Min. *0.*8MPaG (C.S.T: R*2 = **0°C)
