Automotive A/C Nitrogen Leak Detector Kit Easily pre-check systems for leaks due to loose mechanical connections, hose leaks, evaporators and condensers without using refrigerant and venting into the atmosphere. The leak gets identified, thus. If you expect an external leak, might as well open both sides of the gauge set to get everything filled fast as possible. Nitrogen Leak Test Kit Features: high-quality 1 … 4.Locate the evaporator drain outlet or downstream drain trap. When pressurised nitrogen charged into refrigerant circuitry leaks through a soap solution applied on the circuitry, forms bubbles due to chemical reaction with soap solution. 2021 All Rights Reserved. Because nitrogen is held under greater pressure than the coolant, leaks create an audible hissing or whooshing sound as it exits the system. The components are checked for leaks using a special electronic leak indicator. VCA2026 – R134a low-side Valve Coupler BPR2092 – Single Stage, 2 Gauge Pressure Regulator with relief valve In this test, an AC/R professional will remove all refrigerant from the unit, replace the gas with compressed nitrogen, and listen for any sounds. Nitrogen Gas has the following qualities: (a) inert gas , very dry and non-flammable; (b) does not go into solution with refrigeration oil to create non condensable pressure problems (i.e., after leak testing an HFC (R-134a) system using R-22 and nitrogen, there is typically zero percent non condensables (nitrogen or air), if evacuated afterwards). With this nitrogen leak test procedure, the HVAC technician first removes any remaining freon or Puron and pumps compressed nitrogen into the refrigeration system. Air conditioner UV dye makes leak detection easy. Trending. To begin testing a component, a nitrogen tank or on-site nitrogen generator will be connected to the component.
