Datasheet · MRM75os Datasheet · HVAC/R Tools MRM75os Wipcool MRM75os Refrigerant Recovery Machine with Oil SeparatorRefrigerant recovery machine with a built-in oil separator and a twin-piston oil-free compressor, for group III–V refrigerants, including R32, R1234yf (A2L class) and R410A. Liquid recovery of group V refrigerants up to 3.9 kg/min.  3,9kg/minLiquid recovery, group V 0,7kg/minVapour recovery, group V 10,5kg/minPush/Pull, group V 11,6kgWeight 1. What it is used forThe MRM75os is a refrigerant recovery machine with a built-in oil separator. It has an oil-free, air-cooled reciprocating compressor with two pistons and a 970 W motor. The machine recovers group III, IV and V refrigerants, including R32 and R1234yf (A2L class) as well as R410A.
Refrigerant can be recovered as vapour, as liquid or using the Push/Pull method, and you select the mode with the rotary knob. The digital display and control keys are on top of the housing. After recovery is complete, the machine purges itself with the knob in the PURGE position. - Oil separator with drain. The built-in separator removes oil from the recovered refrigerant, and the drain tube lets you drain it from the machine.
- Twin-piston compressor. The twin-piston compressor recovers group V refrigerants as liquid at 3.9 kg/min, and using the Push/Pull method at 10.5 kg/min.
- Shut-off after recovery is complete. In LP1 mode, the machine switches itself off after recovery is complete and displays the COMPLETE message, while in LP2 mode it runs continuously.
- Rear access to the compressor. The service port at the rear of the housing makes it easier to replace the compressor piston rings.
