The NH₃/CO₂ natural refrigerant cooling system combines ammonia (NH₃) on the primary side and carbon dioxide (CO₂) on the secondary side—delivering an environmentally responsible refrigeration solution with outstanding performance.
By integrating two ultra-low GWP natural refrigerants, the system achieves high efficiency, enhanced safety, and minimal environmental impact—all at once.

NH₃ provides exceptional cooling capacity, while CO₂ offers superior heat transfer performance. Together, they enable powerful cooling with a significantly reduced ammonia charge, improving on-site safety and ensuring full compliance with global F-gas regulations.
The system is further strengthened by our reciprocating refrigeration compressor technology, enhancing operational reliability and energy efficiency. The result is optimized performance, lower operating costs, and reduced carbon emissions.
Sustainable. Efficient. Proven.
A future-ready cooling solution for facilities that demand environmental responsibility, performance, and long-term reliability.

● High Efficiency
Powerful Performance. Lower Energy Consumption.

Our reciprocating compressors are engineered to minimize compression loss and maximize output. By optimizing internal gas flow and enhancing valve responsiveness, they deliver superior compression performance with less input energy.
Even under fluctuating load conditions, the system maintains stable efficiency—supporting overall energy savings across your refrigeration operation. Improved operating efficiency also means reduced running costs and lower CO₂ emissions, making it a smart and sustainable choice for modern facilities.

● Compact Design
Flexible Installation. Maximum Space Utilization.

Designed with space efficiency in mind, our compressors feature a compact layout optimized for real-world installation conditions. Strategic component placement allows for a smaller footprint within the same performance class.
Ideal for retrofits and confined machinery rooms, the design reduces piping interference and improves on-site installation flexibility.

● Easy Maintenance
Less Downtime. Greater Productivity.

Serviceability is built into every detail. From routine inspections to parts replacement, maintenance tasks can be performed quickly and efficiently.
Durable, long-life components reduce replacement frequency, helping minimize downtime and lower long-term maintenance costs.
