HASEGAWA VM42 RMCompound Compressor and Spare Parts

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 = 14F, R22 = 5F)

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

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

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

RM type compressor

Max. Determined by motor capacity.
