The Nu-Calgon NUCAL-4050-15 is a UV leak detection kit designed for locating refrigerant and fluid leaks in HVAC and refrigeration systems. The kit includes a high-intensity UV LED flashlight and fluorescence-enhancing glasses that improve dye visibility under UV light. It is intended for use with UV dye-injected systems and is well suited for identifying larger leaks during service calls. HVAC technicians and refrigeration service pros use this kit as part of a complete leak detection workflow when UV dye is already present in the system.
This kit is designed for use with Nu-Calgon EasySeal Direct Inject-UV dye, specifically part numbers 4050-11 and 4050-12. It is also ideal for use alongside the Nu-Calgon Fluorescent Gas Leak Detector. The combination of the UV flashlight and enhancing glasses makes fluorescent dye traces easier to spot in confined equipment spaces, including coil cavities, line sets, fittings, and brazed joints on residential and light commercial systems.
Designed for use with Nu-Calgon EasySeal Direct Inject-UV dye part numbers 4050-11 and 4050-12, and is ideal for use with the Nu-Calgon Fluorescent Gas Leak Detector. Suitable for HVAC and refrigeration systems where UV dye has been introduced for leak detection purposes.
UV leak detection is performed by licensed HVAC or refrigeration technicians after UV dye has been circulated through the system. Always follow EPA Section 608 requirements when working with refrigerant-containing systems. Power down or isolate equipment as required before inspecting joints, coils, and fittings. Avoid looking directly into the UV flashlight beam and ensure the fluorescence-enhancing glasses are worn during inspection to protect eyes from UV exposure.
