Leak detection

One of the most important tasks in automotive air conditioning service is leak detection. In many cases a lack of refrigerant is the reason for a decreasing performance of the A/C system. Before recharging the A/C system the service technician needs to check whether the loss of refrigerant came ‘naturally’ due to the life-time of the A/C system or because there is a leak. The four most important methods for detecting leaks are: Leak detection with electronic leak detectors Tracer gas leak detection Leak detection with Nitrogen and leak detection spray UV leak detection
