Robinair’s new electronic variable displacement compressor test module helps eliminate misdiagnosis

Module is designed to work with multiple variable displacement compressors on a wide range of vehicles

Warren, Mich.—Robinair announced the release of an electronic variable compressor tester this week, the EVDC100. The tester saves technicians time when repairing electronic control valves by eliminating misdiagnosis and performing unnecessary work, company representatives stated.

The EVDC100 works by varying voltage supplied to the refrigerant control valve on the compressor to verify valve function, mimicking a properly functioning compressor valve for a quick and accurate diagnosis. It’s designed to work with multiple variable displacement compressors from suppliers such as Denso and Valeo, used on a wide range of vehicles from OEMs including Ford, GM, Chrysler and Toyota.

Powered by the vehicle’s battery and eliminating the need for technicians to purchase separate batteries, the tester’s connector adapters work on both old and newer style compressors and include heavy-duty battery clips. It also includes a long six-foot wiring harness, which gives technicians the freedom to move around their repair bay and more easily access the valve and battery, in addition to removable cable assemblies for easy replacement.
