Containerised NH₃ with Pumped CO₂
Secondary Coolant
Efficient modular refrigeration for chilling and freezing
In an NH₃ + CO₂ secondary coolant system, ammonia acts as the primary refrigerant to cool carbon dioxide in a cascade heat exchanger. The condensed liquid CO₂ is then pumped as a phase-change secondary refrigerant to air coolers, blast freezers and plate freezers, providing efficient cooling to the end application.
Operational Advantages
• No dedicated compressor plant room: Reduces building requirements and simplifies installation
• Modular, scalable capacity: Add units as output grows without redesigning the full system
• Energy-saving performance: Uses 20-30% less energy than conventional Freon systems
• Straightforward operation: Simple system design makes day-by-day running easier
• Reliable redundancy: Independent units help protect production continuity
• Reduce installation costs: Smaller CO₂ pipework reduces material requirements and lowers on-site installation costs
Everflo’s containerised CO₂ solution combines efficient cooling, lower system losses, safer occupied-space integration and easy modular expansion.
