A small amount of fluorescent dye is added to an air conditioning, refrigeration or industrial fluid system and allowed to circulate. The dye escapes with the system’s refrigerant or fluid and remains at all leak sites. When the system is scanned with a Spectroline^® TITAN^® UV/Blue™, Blue Max Plus™, or ultraviolet inspection lamp, the dye fluoresces brilliantly to pinpoint the exact source of every leak. Proven to find multiple and intermittent leaks undetectable by any other method. Even leaks smaller than 1/8 ounce per year!

Easily verify repairs by removing the dye from the leak sites with GLO-AWAY™ dye cleaner and then reinspect. The dye can remain safely in AC&R or fluid systems indefinitely for future leak inspections.

Fluorescent leak detection is the only method that can be used for both accurate diagnostics and as part of a comprehensive preventive maintenance program.

AR-GLO^® fluorescent dyes are the only dyes that are co-solvent free and OEM-approved by major compressor, refrigerant, lubricant and AC&R equipment manufacturers.

AR-GLO dyes are super-concentrated, lubricant-specific and proven in over 40 million AC&R systems worldwide.

AR-GLO dyes are completely safe and will not alter or impair lubricant properties, which could lead to equipment damage and costly downtime. They have been successfully tested in accordance with ASHRAE Standards 97 and 86.
