Nitrogen Detection and Bubbling Although not as inexpensive as an electronic leak detector test, a nitrogen leak detector test may provide more insight regarding the problem. Nitrogen will be released to elevate the pressure within the test component to a low pressure while forcing any air, debris, or other substances out of the component. For advanced leak detection the electronic halogen detector cannot be used. Designed for detecting and locating leaks in automotive air conditioning systems using pressurised Nitrogen gas. Trending. If you expect an external leak, might as well open both sides of the gauge set to get everything filled fast as possible. 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. What is the procedure?

An air conditioning technician replaces remaining refrigerant with compressed nitrogen, which allows you to actually hear any existing leaks. But when making repairs that open the refrigeration system up, you may want to do a quick leak check by boosting the system up to 200psi or more. While some folks prefer this method, it can be expensive. You use dry nitrogen at 150 psi then you switch your gauges over to nitrogen decay test . 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. 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. Step 4: Use an electronic leak detector. Log in Register. You can also use nitrogen with a trace of either helium or hydrogen for the pressure testing (available from several suppliers).

A majority of leaks are found through an electronic leak detector, visual examination, or a proprietary bubble solution. 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. 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. For those of you worried about using compressed air because of moisture. 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. Besides doing a vacuum pull to remove moisture and check for leaks (with a Welch 1397 pulling a whopping 17.7 cfm ), I want to do a pressure test to test for leaks.I've seen that many people do it with Nitrogen and a little R-22, but I don't have a Nitrogen tank laying around and don't want to buy or rent one if it is not necessary.

Co Reg No. However, some of our customers require a nitrogen leak test and we need to figure out how to meet those standards. An AC leak test with nitrogen—the preferred test by Homesense technicians—adds a greater degree of clarity to leak detection, though for slightly more cost. Both helium and hydrogen have small molecules and leak at a lower pressure than pure nitrogen. There could be a leak that’s venting nitrogen into the air you’re breathing. Then repeat the "standing test" to determine of there is a decrease in leak rate after the stabilization of the vacuum. cost effective.

Be sure to visit our website and follow us on Facebook, Twitter, YouTube, and LinkedIn! 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). Further, nitrogen gas is inert and has the capability to absorb moisture to a certain extent. This is where nitrogen is pressurized into the refrigerant lines and then pressure-tested to identify leaks. I don't hesistate to push 400 PSI to an A/C system with nitrogen, Over the road trucks run 250 - 300 PSI on the high side, might as well make a leak rather than chase one. Unlike the standard bubble test, Best Bubbles Fluo fluoresces for easy detection, comes pre-mixed in a convenient applicator spray bottle, and can be easily removed with our Brilliant Remover. With this nitrogen leak test procedure, the HVAC technician first removes any remaining freon or Puron and pumps compressed nitrogen into the refrigeration system. 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. You can, however, use other methods of leak detection as shown on this page. Charge the system to its full capacity if the vacuum leak test passes. Leak detectors come out first when troubleshooting.
