Why use Nitrogen for leak testing?

We use Oxygen Free Nitrogen (OFN) for leak testing. It would be illegal to re-gas a system to use the refrigerant as a means of leak detection. The pure form of Nitrogen is a naturally occurring gas in the air that we breathe and so is safe and legal to use. The Nitrogen is inserted into the system under high pressure thus simulating a system in operation and revealing any leaks in the system.

Oxygen Free Nitrogen (OFN) is used for leak testing because it is safe for the environment and can pressurise the system sufficiently to be able to leak test. You can not charge a system with refrigerant without leak testing first as this is illegal!
