For years, ultraviolet-activated fluorescent dye has been the ‘standard’ for reliable leak detection in systems that contain a liquid carrier; such as systems with Freon® or hydraulic fluids. However, prior to our technology, these fluorescent dyes could not be used in systems that did not contain a liquid (dry systems) because the liquid was required to be the ‘carrier’ for the fluorescent dye.
Our revolutionary patented chemical and method for delivering the ultraviolet-activated Diagnostic Smoke® vapor eliminates liquid carriers from the process. UltraTraceUV® is a solution containing a special fluorescent dye chemical, used in combination with most of the machines using STAR technology, that when vaporized produces a Diagnostic Smoke® vapor that takes the fluorescent dye air-borne. This technology actually suspends the fluorescent dye in the Diagnostic Smoke® vapor to carry it directly to leaks wherever they may be. Now any ‘dry system’ can be leak tested. And pinpointing the leaks is simple; just introduce the Diagnostic Smoke® vapor containing UltraTraceUV® dye solution into any dry system suspected of having leaks. Then simply look for the exiting smoke or shine an ultraviolet light and look for the fluorescent deposit marking the exact location of the leaks. This method will allow you to use ultraviolet-based leak detection in systems never before possible. Most industries can benefit from this technology.
Many dyes are harmful and can easily contaminate sensitive systems. Our patented UltraTraceUV® is formulated in such a way that does not contaminate systems and it also easily ‘releases’ from components and systems. Independent laboratory tests conducted in collaboration with the U.S. Navy demonstrate that it is also compatible with fuels, fuel systems and does not cause Hydrogen Embrittlement. Independent laboratory tests conducted in collaboration with major OEMs demonstrate that it is compatible with and does not negatively affect electrical systems, which is one reason major OEMs such as G.M. have approved the Diagnostic Smoke® for testing electric vehicle battery containment systems by introducing the Diagnostic Smoke® inside the battery containment systems. In fact, unlike most dyes, it also easily wipes clean from external surfaces once the leak has been identified. Commercially-available dyes should not be added to generic mineral oils to try and replicate the effects due to the high probability of creating a contaminant to systems.
The Diagnostic Smoke® vapor can be generated using compressed air; or any non-combustible gas – such as nitrogen – when testing potentially volatile systems such as a vehicle’s fuel vapor recovery (EVAP) system or an electric vehicle battery containment system. Other leak detection applications include virtually any system that does not contain a liquid. In an automotive system this may include the vacuum and exhaust systems of a vehicle; brake boosters, cooling systems, turbochargers, intercoolers, diaphragms and gaskets. With a special adapter, the Diagnostic Smoke® vapor can be used to determine wind and water leaks entering the vehicle’s passenger or luggage compartments.
Test Safely! We support SAE recommended safer testing practices of using an inert gas such as nitrogen, as the carrier gas for the smoke vapor, when testing a vehicle’s potentially explosive systems, such as fuel vapor recovery (EVAP) system and an electric vehicle battery containment system. In fact, virtually all automakers that have approved the use of smoke vapor technology recommend or require the use of nitrogen when producing the smoke vapor.
