Nitrogen Regulator for A/C Leak Detection and Pressure Testing Brand: Parts Express. Lastly, even if you determine the system will not maintain a vacuum, it does not indicate where the leak is and additional leak test methods will be required. In the given application, it is extremely important that water does not leak from the apparatus. S2 3AB If there is no leak, the 2nd leak rate in the system the leak rate should be considerably less than the first indicating progress in the job of dehydration. Active leaks most likely will be found using an electronic leak detector. IMPORTANT: DO NOT exceed the recommended pressures (use a pressure regulator) and DO NOT operate the air conditioning system with oxygen free nitrogen (OFN) in the refrigerant circuit. If you expect an external leak, might as well open both sides of the gauge set to get everything filled fast as possible. 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). Step 4: Use an electronic leak detector. Nitrogen is then added to generate a practical test pressure). The leak detection mix is compatible with all standard pressure testing equipment (including nitrogen regulators) and is suitable for leak testing any size of refrigeration system. LDG2094 – Low Pressure Gauge with hose fittings and ball valve This could be from the AC unit itself, or from any point where you’ve got lines connecting with the nitrogen tank or AC unit.
