FAQs: Flash™ Detect UV Dye + Flash™ Detect Inject UV Dye
1. Are Flash™ Detect and Flash™ Detect Inject compatible with all oils and refrigerants?
Yes, both are compatible with all oils and refrigerants. Flash™ uses the systems refrigerant to inject
without the use of propellants such as propane, isobutane, or hydrocarbons. Use as per application
guidelines below:

LARGE SYSTEMS
6+ tons/20+ kW
1 Flash™ Detect or
Flash™ Detect Inject for
every 64oz./1.8L of
system oil

2. Why should Flash™ Detect be used?
Flash™ Detect should be used to pinpoint the location of a leak in a HVAC/R system. Flash™ Detect can
also be used before an HVAC/R system has developed leaks, to reveal future leaks as they occur.
3. How does Flash™ Detect work?
Flash™ Detect is a high resolution universal ultraviolet dye that visibly fluoresces at 405 nm to the human
eye under true ultraviolet light without glasses. Unlike all other UV dyes, Flash™ Detect does not use an
oil carrier but instead uses Dry R™ moisture eliminator. Dry R™ allows the dye to inject through our
patented misting orifice directly into the refrigerant stream instantly distributing throughout the system.
Contractors can begin looking for leaks 15 minutes after injection.
4. Can any ultraviolet light be used to fluoresce Flash™ Detect?
Yes, however best results are obtained by using lights with a 405 nm output such as DiversiTech® UV
lights. Note: When using blue or black lights, glasses will be required.
5. Will Flash™ Detect solidify in the system?
No, Flash™ Detect UV dye will always remain in a stable state within a HVAC/R system. Dry R™ ensures
stability of the UV dye preventing it from crystallizing unlike all other dyes which will react with moisture
to form solids.
