WESTBURY, NY — According to Spectronics Corporation, its patented Spectroline® Glo-Stick® dye capsules are a mess-free tool for adding fluorescent leak detection dye to air conditioning and refrigeration systems. The disposable capsules are prefilled with a measured dose of AR-GLO® dye. Technicians do not have to measure and pour dye when adding it to HVACR equipment, so spills and cleanups are history, says the company.

With the Glo-Stick capsules, the dye is injected into an operating air conditioning or refrigeration system where it mixes with the refrigerant and lubricant as they circulate through the unit. Wherever refrigerant may leak out, so does the dye. The refrigerant will evaporate, but the fluorescent dye remains at the leak site. When the system is scanned with a high-intensity Spectroline ultraviolet or UV/blue light lamp, the company says, the location of each leak is revealed by a bright yellow-green glow.

AR-GLO is compatible with all commonly used refrigerants, including R-134a and blends, says the company. It is said to be solvent-free, so it cannot impair lubricant properties, which could lead to excessive wear or damage to system components.
