Bulgin CO₂ Charging Kit for R744 Liquid CO₂

The Bulgin CO₂ Charging Kit is a professional charging solution designed specifically for the safe and efficient transfer of liquid R744 (CO₂) refrigerant into commercial refrigeration, HVAC and process cooling systems. Engineered for the demanding pressures associated with CO₂ refrigeration, these kits enable technicians to perform high-speed liquid charging operations on both transcritical and subcritical R744 systems.

Each kit incorporates high-pressure PTFE-lined stainless steel braided charging hoses, manifold assemblies, isolation valves and pressure relief devices, providing a complete solution for connecting liquid CO₂ cylinders to refrigeration systems during commissioning, servicing and refrigerant charging operations.

The Bulgin CO₂ Charging Kit assists with the rapid charging of R744 systems while maintaining compatibility with the pressures and operating requirements commonly encountered in commercial refrigeration, supermarket systems, industrial cooling applications and CO₂ chillers.

General Requirements

Suitable for use on both transcritical and subcritical R744 refrigeration systems.

Charging operations must be performed by qualified and authorised personnel utilising appropriate personal protective equipment (PPE). Contact with liquid CO₂ can cause severe cold burns and frostbite, while elevated concentrations of gaseous CO₂ may present an asphyxiation hazard in confined or poorly ventilated areas.

The guidance provided is intended as a general reference only and does not replace established site procedures, risk assessments, manufacturer instructions or applicable regulatory requirements. System configurations may vary between installations. Always consult the relevant equipment operating manual before commencing charging operations.

Safety Information

R744 (CO₂) refrigeration systems operate at significantly higher pressures than many conventional refrigerants. Before charging, ensure all equipment, hoses, manifolds and system components are suitable for the intended operating pressure and are in good working condition.

Pressure relief devices should never be removed, bypassed or modified. All charging equipment should be inspected regularly and replaced immediately if signs of wear, damage or deterioration are observed.

NOTE. This equipment is designed for use with R744 (CO₂) refrigerant only.

Do not attempt to use this equipment with any other gas type.
