Datasheet · MRM75 Datasheet · HVAC/R Tools MRM75 Wipcool MRM75 Refrigerant Recovery MachineRefrigerant recovery machine with 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, digital pressure display.  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 MRM75 is a refrigerant recovery machine with an air-cooled, oil-free 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.
You can recover refrigerant as vapour, as liquid or by the Push/Pull method, and you select the mode with a 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. - Twin-piston compressor. The twin-piston compressor recovers group V refrigerants as liquid at 3.9 kg/min, and by the Push/Pull method at 10.5 kg/min.
- Inlet and outlet pressure on screen. The display shows the inlet (IN) and outlet (OUT) pressure simultaneously in the selected unit: inHg, kPa, psi, kgf, bar or MPa.
- Shutdown after recovery is complete. In LP1 mode the machine switches off automatically once recovery is complete and shows 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.
