Decreasing refrigerant charging amounts in automotive A/C systems requires more sensitive leak detection equipment. This is where WAECO provides a convincing solution with its highly fluorescent additives, lamps and goggles which are perfectly coordinated. UV leak detection additives are well proven for their fast, easy to use and highly accurate leak detection at a competitive costs. Caution is advised because poor quality leak detection additives can cause wear on the seals in the air conditioner and in the A/C service unit. Moreover, they can contain solvents that impair the refrigerant oil‘s lubricating ability. For use with refrigerant oils (PAG, mineral oil, ester), there’s currently only one UV additive available that contains no solvents whatsoever, features an excellent fluorescence and is based on high-quality refrigerant oils only. Its name: TRACER®. When properly applied, this additive is absolutely safe for use in all types of automotive air conditioners and A/C service units. Special TRACER® leak detection additives have already been approved for use with new refrigerants, such as CO2 and R1234yf. TRACER® products contain 10 times more dye than other UV additives, which makes them much more effective when it comes to tracing smaller leaks.
