Simply add WFS-81 to the system in the appropriate quantity and allow it to circulate for at least 5 min. Reduce ambient brightness as much as possible and examine all areas using a UV light or blue light system
After repairing and cleaning the leaks with degreaser or the usual cleaner, simply run and check the system again.

There is a leak in the engine, the slide valve is leaking or a hydraulic valve is leaking fluid. These and other areas of application such as refrigeration unit maintenance or fuel leakage detection can be easily and effectively implemented with the SECU-CHEK fluorescent dyes and ensure lower costs and greater safety as well as prevent long maintenance downtimes. WFS-81 is the cheaper universal solution as an alternative to this product for water circuits: WATER-GLO ULTRA BLUE fluorescent dye (SPI-WGB / WATER-GLO 801) – leak detection / leak detection of aqueous systems
