2 Valve Transcritical CO2 manifold

Javac FR4312-E25 CO2 Trans-Critical 2-Valve Manifold

The Javac FR4312-E25 is a professional 2-valve manifold designed specifically for CO2 trans-critical (R744) refrigeration systems. Rated to handle the extreme pressures of transcritical CO2 operation, it features CO2-compatible seals and materials throughout — making it an essential tool for engineers working on next-generation natural refrigerant systems.

CO2 transcritical systems operate at significantly higher pressures than conventional refrigerants, requiring specialist equipment. Standard manifolds are not suitable for R744 applications.

Key Features & Benefits

• Designed for CO2 trans-critical (R744) systems – not suitable for use with standard refrigerants as a replacement
• High-pressure rated to 160 bar – handles the extreme operating pressures of transcritical CO2
• CO2-compatible seals and materials – safe, reliable operation with R744
• 2-valve design – high and low side service valves for system diagnostics and charging
• 1/4" SAE connections – standard HVAC/R fittings
• Part of the Javac CO2 Pro specialist range
