EVC-1 Variable Displacement Compressor Tester

The AirSept EVC-1 Variable Displacement Compressor Tester offers a quick, simple diagnostic process to help rule out an electronically-controlled compressor as a cause of air conditioning system performance problems. It is designed to activate the compressor’s electronic control valve to test compressor operating efficiency. It works on all clutchless, direct drive, electronically-controlled air conditioning compressors. The EVC-1 connects to the compressor and to its electronic control solenoid valve wiring harness. It bypasses the vehicle A/C system controls, and activates the valve directly to increase or decrease the mechanical load on the compressor in increments. The EVC-1 shows the A/C system high and low side temperature changes in response to the varying load command from the electronic control solenoid valve. The unit sends commands to the compressor’s electronic control solenoid valve without having to connect to the vehicle’s electrical system. Thus, it does not disrupt any A/C system circuits, and will not set an error code in the vehicle’s on-board diagnostic system.
