System flushing, correct oil and refrigerant quantities, and the role of the MSG MS111 test bench and MS101P flushing unit in compressor replacement.
The compressor is the heart of a car’s AC system, pumping refrigerant and building the pressure needed for condensation — and it is also the component that fails most often. MSG Equipment stresses that a proper repair requires knowing exactly where the fault lies and the compressor’s overall condition, which is why it developed the MS111 compressor test bench and the MS101P flushing unit.
- Follow the manufacturer’s refrigerant, oil and UV dye quantities strictly.
- Replace non-reusable parts such as aluminium tubes.
- Never use leak-sealing “repair” additives.
A compressor with a seized piston group must be replaced, the system flushed, and the new unit carefully started up and tested.
