Why Nitrogen Testing for CO2 Systems?

CO2 refrigeration systems operate at significantly higher pressures than traditional HFC systems (up to 120 bar operating pressure). Nitrogen pressure testing at 200 bar ensures:

• Complete leak detection before expensive CO2 charging
• System integrity verification at pressures exceeding operating conditions
• Compliance with safety standards for high-pressure refrigeration
• Prevention of moisture contamination during testing
• Cost-effective testing compared to using CO2 refrigerant

CO2 Refrigeration Systems:

CO2 (R744) is increasingly used in commercial refrigeration due to its low environmental impact and excellent thermodynamic properties. However, CO2 systems require specialised high-pressure equipment and testing procedures. This regulator is specifically designed for the demanding requirements of CO2 system commissioning.

UK F-Gas Compliance:

Proper pressure testing with nitrogen is mandatory under UK F-Gas regulations before charging any refrigeration system. For CO2 systems, the higher test pressures ensure system safety and regulatory compliance.
