Errecom TR1133 Trace Brilliant UV Dye makes refrigerant leaks easy to spot — even through ice or frost — so you can diagnose fast and get on with the repair. Compatible with common AC/R refrigerants and oils, it’s a clean, non-volatile formula that won’t gum up components. Too easy.
Why technicians rate it (features & trade benefits)
- Shows through frost & ice — bright red traces that stay visible in cold rooms and iced-up coils; no more squinting.
- Non-volatile, solvent-free feel — designed to avoid gumming/sludging, protecting TXVs and seals.
- All-round compatibility — retailers specify use across CFC/HFC/HCFC/HFO and common lubricants (follow OEM advice).
- Includes flex adapters — 1/4″ & 5/16″ SAE adapters for fast hook-ups on splits and refrigeration plant.
- Backed by SDS — not classified as dangerous; dark-red liquid, FP ~170 °C; density ~0.9 g/mL.
Why this product matters
Real-world: on a Melbourne cold-store call, a slippery intermittent leak kept dodging the sniffer. We dosed with Trace Brilliant, ran the system, and the UV torch lit up a neat red trail under frost on a flare — repair done, system back online. That’s fewer call-backs and a happy client — bloody good outcome. For method guidance, AIRAH notes fluorescent dye is a valid technique when used with care and in combo with other detection methods.

Pro tip
Inject the dye, run the system long enough to circulate oil/dye to the leak path, then scan slowly with a UV torch. Wipe suspect joints clean first to avoid false trails. Keep it tidy — a little goes a long way. No worries.
