Why CO2 (R744) Refrigeration?

CO2 is increasingly adopted in commercial refrigeration due to:

• Zero ozone depletion potential (ODP) and low global warming potential (GWP)
• Excellent thermodynamic properties for refrigeration
• Natural, non-toxic, and non-flammable refrigerant
• Cost-effective and widely available
• Compliance with F-Gas regulations and environmental legislation

CO2 System Considerations:

CO2 refrigeration systems operate at significantly higher pressures than traditional HFC systems. This regulator is specifically designed to handle:

• High operating pressures (up to 100 bar outlet)
• Transcritical operation where CO2 exceeds its critical point
• Safe charging procedures for high-pressure systems
• Precise pressure control for optimal system performance

UK F-Gas Compliance:

CO2 (R744) is classified as a natural refrigerant and is exempt from many F-Gas restrictions. However, proper handling equipment and F-Gas certification are still required for working with refrigeration systems. This regulator meets professional standards for CO2 system servicing.
