This is a decent method for doing a quick leak check before pulling a vacuum. 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. While some folks prefer this method, it can be expensive. VCA2026 – R134a low-side Valve Coupler NOTE: Recover the refrigerant and Nitrogen gas into recovery cylinder after completion of a test. Air conditioner UV dye makes leak detection easy. One method of finding holes in a system is to use compressed nitrogen gas. 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). What is the procedure? Like Best Bubbles Fluo, Brilliant residue can be easily removed with Brilliant Remover to prevent future false-positives. Further, nitrogen gas is inert and has the capability to absorb moisture to a certain extent. First and foremost you cannot do it.Experienced technician only can identify, pinpoint and attend to it. Then, nitrogen with a little refrigerant is introduced after the leak is fixed to test it with your leak detector. LDG2094 – Low Pressure Gauge with hose fittings and ball valve An air conditioning technician replaces remaining refrigerant with compressed nitrogen, which allows you to actually hear any existing leaks. Telling the Difference Between Moisture and a System Leak Finding holes in AC/R systems can be a challenge.

Make sure this fits by entering your model number. With this nitrogen leak test procedure, the HVAC technician first removes any remaining freon or Puron and pumps compressed nitrogen into the refrigeration system. Log in Register. Leaks are detected using an electronic leak … Search. Most low sides of systems have a working pressure of 150 psig, but always read the nameplate on the evaporator section for test pressure specifications. You use dry nitrogen at 150 psi then you switch your gauges over to nitrogen decay test . If you expect an external leak, might as well open both sides of the gauge set to get everything filled fast as possible. Electronic leak detectors must be positioned on any surface that may have a leak to scan it, which can be incredibly challenging in tight quarters. As the nitrogen gas – colorless and odorless – escapes into the room the oxygen content of the air is going to become lower. 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. Like the old reliable bubble test, Best Bubbles Fluo clings to coils and creates a bubble at the site of any leaks.
