The A/C Compressor Evaluation Test Machine (CETM) is designed to evaluate compressors without the operator needing to be familiar with the design and functionality of compressors. The most recent update of the CETM has been manufactured for compressor manufacturers and remanufacturers with more automation and capability. The test imitates the loads that would be put on a compressor in an actual vehicle air conditioning system.
The CETM requires a computer loaded with the TDS Compressor Evaluation Software (TCES).
A list of compressor models is included in the software for convenience, but it is possible to test any compressor with a given pulley diameter and displacement per revolution. It is not necessary to know if the compressor is a fixed or variable model…the machine can determine the difference and run the correct test for either type.
