Air conditioning nitrogen pressure test
For precise leak detection and system integrity verification, our air conditioning nitrogen pressure tests are invaluable. Essential for robust, compliant AC operation.
Air conditioning nitrogen pressure test
An air conditioning nitrogen pressure test is a critical procedure for verifying the sealed integrity of your system's refrigerant circuit. It's performed after pipework alterations, new installations, or when a refrigerant leak is suspected but not yet located. This test ensures that the system can hold its operating pressure without any loss, which is fundamental to efficient cooling and F-Gas compliance.
Our engineers introduce dry, oxygen-free nitrogen (OFN) into the isolated AC system at a specific pressure, well above typical operating pressure. The system is then carefully monitored with precise gauges over a period, usually several hours or overnight. A sustained pressure drop indicates a leak, which can then be methodically located.
