Refrigerant Dye and Fluorescent Leak Detecting

Refrigerant Fluorescent Dyes and leak detection

Refrigerant dye is another tool that is used to determine leakage problems. Refrigerant dye system produces a bright red color in the place of leakage. Most leaks show in a short time. However, in the period of up to 24 hours may be necessary in some cases.

In most systems, all the refrigerant must be replaced refrigerant containing the dye. This is necessary in order to achieve maximum leak detection. РљСЂР°СЃРёС‚РµР»СЊ'method depends on the rate of oil circulation. Thus, it may take a long period of time (up to 24 hours)to indicate leaks.

UV fluorescent leak detection procedure is another method. Fluorescent additive propagates through the system. Leakage of the refrigerant was found by scanning the system with UV light (Fig. 12-57. This method can be used with different refrigerants including R-134a...
