The compressor is a frequent cause of AC failure. The MS111 tests piston, axial-piston, rotary and scroll compressors at 12/24 V and produces a report.
When a car air conditioner does not cool properly or fails completely, the culprit is often the compressor, which runs under heavy load. Excessive noise and oil traces on the housing are typical symptoms.
MSG’s MS111 stand checks the condition of compressors running on R134a and R1234yf, is used for running-in after repair and pre-sale checks of new aftermarket compressors, and produces an inspection report:
- Belt-driven piston, axial-piston, rotary and scroll compressors
- Automatic and manual modes, 12 V and 24 V supply
- Open-circuit, short-circuit and diode checks on clutches and control valves
MSG recommends planning equipment purchases before the summer season begins.
