Description
- For R134a air conditioners
- For R123yf air conditioners 1× adapter 5380 696 and 1× quick coupling 5380 694 are required
- The nitrogen emerges at the leak and can be detected by a hearing test or leak detection spray (e.g. Förch Leak Detector 6730 0800) (blistering). An electrical nitrogen detection is not possible.
- The testing is made with realistic pressure conditions in the system
- Nitrogen is more favourable than cooling and contrast agents
- The nitrogen possibly binds residual moisture after vacuuming in the system
- No environmentally hazardous emerge of cooling agents during and after leak detection
