Nitrogen … Most kits require the insertion of dye into the low side air conditioning fitting. Due to the fact that hydrogen is lighter than air, the sensor needs to be moved slowly above the suspected leak (electrical connections/components). For leak tests, a filling adapter is required for the service connection as well as a tube adapter. Since air conditioning experts cannot be sure whether there is a leak or whether the refrigerant loss is the normal loss over time, careful leak detection is a must. Detecting a leak in the air-conditioning system using forming gas. N.B Picture is for illustration purposes only.

Mastercool’s new nitrogen regulator is specifically designed to meet the specifications of HVAC/R and automotive A/C systems. Because nitrogen is held under greater pressure than the coolant, leaks create an audible hissing or whooshing sound as it exits the system. Our cookies do not contain any personal information. Increasing the nitrogen pressure in the system with NITROKITG to a maximum of 200 psi will cause a sound of escaping gas at the point of the leak. 1/4” SAE flare outlet port, with control valve, to keep pressure on the regulator at all times This method involves the production of positive pressure through nitrogen or negative pressure through vacuum by the AC service unit. On this page you can find out which methods are efficient for detecting leaks in the refrigerant circuit. The leak detection agent is sprayed on from outside. Easily pre-check systems for leaks due to loose mechanical connections, hose leaks, evaporators and condensers without using refrigerant and venting into the … The system is filled with Oxygen Free Nitrogen to 10 bar and left for 10-20 minutes. The exact amount of contrast agent is injected using the Spotgun cartridge gun or the Pro-Shot system. 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. Shop in store or online to choose from the best a/c leak detectors for cars and trucks. If you have a really tricky leak to find, a few ounces of R134a in the system before pressurising with Nitrogen helps to give a trace for a refrigerant detector to pick up on, I dont like to take the system above 200psi for fear of damaging the evaporator. The pressure sensor for the system also presents a popular place to find leaks check at the base and at the electrical connector.
