VM42RM compressors should not be operated beyond the following limits:

Compressor RPM: Max. = 1250 rpm (VM =1500rpm) Min. = 600 rpm
Compression ratio Max. = 15 Target Max: R717 – 10, R22 – 11
Pressure difference Max. = 227 psi (16.47 kg/cm″) [1.6MPa]


Suction pressure, Two stage compressors:

Max. 28 psig (C.S.T: R717 = 14°F, R22 = 5°F)

Max. 0.2 MPaG (C.S.T: R717 = -10°C, R22 = -15°C)

Min. 11 psig (C.S.T: R717 = -76°F, R22 = -94°F)

Min. -0.08MPaG (C.S.T: R717 = -60°C, R22 = -70°C)

RM type compressor

Max. Determined by motor capacity.

Min. 11 psig (C.S.T: R22 = -94°F)

Min. -0.08MPaG (C.S.T: R22 = -70°C)
