R744 (CO2) Refrigeration Tools & High-Pressure Equipment

R744 (carbon dioxide) is a natural refrigerant with a GWP of 1 — increasingly specified for commercial refrigeration, supermarket systems, cold storage, and CO2 heat pump water heaters. R744 operates at significantly higher pressures than conventional refrigerants, requiring purpose-built high-pressure tools and equipment. Airconspares stocks specialist R744 CO2 tools from Javac, including sub-critical and transcritical manifold sets. Same-day dispatch from UK stock. Rated Excellent 4.8/5 on Trustpilot.

Why R744 Requires Specialist High-Pressure Tools

R744 operates at up to 60 Bar in sub-critical systems and up to 140 Bar in transcritical systems — far exceeding the pressure ratings of standard HVAC tools. All equipment used on CO2 systems must be rated for the specific operating pressures of the system. Using standard HVAC tools on R744 systems is dangerous and non-compliant.

R744 Manifold Sets

The Javac FR1308-4R-E20 Sub-Critical 4-Valve CO2 Manifold and 2-Valve Transcritical CO2 Manifold are stocked for R744 specialist work. Sub-critical manifolds suit cold storage and low-temperature commercial refrigeration. Transcritical manifolds are required for supermarket rack systems and CO2 heat pump applications operating above the critical point. Browse all manifold sets.

R744 Applications

CO2 refrigeration is specified across supermarket centralised refrigeration systems, industrial cold rooms and warehouses, food processing facilities, CO2 heat pump water heaters, and ice rink refrigeration. R744 is not subject to F-Gas phase-down regulations, making it a future-proof refrigerant choice for commercial operators.

Safety Considerations for R744 Work

CO2 is heavier than air and accumulates in low-lying areas — adequate ventilation and CO2 gas detection are essential in plant rooms and enclosed spaces. All hoses, fittings, and equipment must be rated for the operating pressures of the specific system. Specialist training in high-pressure CO2 systems is required before undertaking R744 service work.
