Why use N2 (Nitrogen) Gas for Leaking Test ?

When dealing with air conditioner gas leaks in our homes or offices, we often resort to using Nitrogen (N2) gas for a Leak Test. This is especially crucial when the leaks are so minuscule that conventional leak detectors fail to identify them. Nitrogen gas becomes essential for conducting thorough leak checking tests.

Aircon gas leaks typically stem from issues with the compressor or copper pipes developing holes due to rust. The compressor’s role in circulating refrigerant is pivotal, and any failure in its function can result in refrigerant leakage. Similarly, corroded copper pipes with holes contribute to gas leaks.

Initially, we employ a leak detector to identify gas leakage. If the source remains elusive, Nitrogen gas is employed to meticulously test and pinpoint the location of the gas leakage within both indoor and outdoor copper pipe units.

The application of Nitrogen for leak testing extends beyond air conditioning concerns. This method is regularly employed in various industries to assess the integrity and flow of channels within industrial transport equipment and storage systems. Nitrogen’s versatility makes it a popular choice for leak testing in industries beyond petroleum, offering several advantages in the detection of defects within conduit systems.

Once the location of the copper pipe leakage is identified, necessary actions are taken. For minimal holes (1 or 2), brazing is employed, while numerous small holes may necessitate the replacement of copper pipes. This ensures the proper functioning of the air conditioner.
