Went to a job after other people had installed this complete unit and guages went on , low on freon . Removes the need to add refrigerant, find leak and recycle refrigerant. Typically, nitrogen gas leak detectors are portable, handheld devices. If you have a sniffer leak detector you can put in about 30 psi refrigerant first (this is only a couple of oz by weight), then nitrogen up to 150 psi, and sniff for leaks. With this nitrogen leak test procedure, the HVAC technician first removes any remaining freon or Puron and pumps compressed nitrogen into the refrigeration system. Second, can you use a sniffer too detect the nitrogen, or how do you detect nitrogen to see if you have a leak.

This single-stage nitrogen regulator is used to test systems for leaks when they do not contain refrigerant. NITROGEN AIR CON PRESSURE LEAK TEST - MASTERCOOL. This leak detection method complies with Article 6, §3 of the EU Directive 2006/40/EC. NOTE: Recover the refrigerant and Nitrogen gas into recovery cylinder after completion of a test. Leak testing with a vacuum doesn't mean there is not leak. We recommend using Nitrogen/Hydrogen mix as Hydrogen is the smallest molecule in the periodic table which will leak easily. DO NOT operate the air conditioning system with oxygen free nitrogen (OFN) in the refrigerant circuit. evaporator leaks). Direct from 3rd Party Supplier Add To Cart: NITROKITG is designed to assist the Technician in locating leaks in automotive air conditioning refrigerant system when it will NOT PASS A VACUUM TEST (large leak). Otherwise, it may be sensible to make the leakage spot visible using leak detection agent. Second question, using nitrogen to check for a/c leaks, do I use a nitrogen tank with regulator, how much pressure can you put into the system, I assume I put the nitrogen. If you cannot find a leak using any of the methods above, you should recover the charge and pressurise with dry (oxygen free) nitrogen. Leak testing with bubble dye solution For basic leak detection, for instance in the area of connections, a bottle of commercially available bubble dye solution can be used. Share - CPS NITROKIT Automotive AC Nitrogen Leak Detector Kit. Air Conditioning Nitrogen Pressure Leak Test Kit. 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. Nitrogen has the following qualities: (a) inert, 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).
