Industrial Chillers & Specialized Applications

  • Decarbonization-ready chiller systems
  • Non-flammable, PFAS-free, and highly reliable
  • Thermal Control Units (TCU), Precision TCU, and process chillers

CO2 refrigeration technology is increasingly adopted in industrial sectors where safety, environmental compliance, and long-term reliability are critical.
It is also widely applied in thermal control systems such as Thermal Control Units (TCU), Precision TCUs, and process chillers, where precise temperature stability, high reliability, and continuous operation are required.

High-Reliability Industrial Applications

CO2 Solutions Where Flammable Refrigerants Are Not Suitable

In advanced industrial environments, flammable refrigerants such as R290, R600a, and A2L refrigerants are often restricted due to strict safety requirements and the presence of ignition sources.
CO2 (R744), a non-flammable, PFAS-free natural refrigerant, provides a safe and highly reliable alternative for these critical applications.

Typical Applications
CO2 compressor-based systems are increasingly used in high-reliability industries, including:

  • Semiconductor manufacturing equipment (etchers, CVD, PVD, lithography chillers)
  • Laser processing and welding systems
  • Industrial 3D printers (SLM, DED, powder sintering)
  • Battery manufacturing equipment
  • Medical systems (MRI, CT, PET, radiation therapy)
  • Data centers and cleanroom HVAC systems
  • Explosion-proof environments (chemical, pharmaceutical, petrochemical plants)
  • Vacuum and analytical equipment (SEM, TEM, mass spectrometry)
  • Aerospace and defense equipment

Why CO2 (R744) Is the Preferred Choice

These applications require non-flammable refrigerants due to high-value equipment, ignition risk, and strict safety standards. CO2 refrigeration systems offer:

  • Non-flammable, inherently safe operation
  • PFAS-free and future-proof regulatory compliance
  • High reliability for continuous and precision cooling
  • Strong alignment with ESG and decarbonization goals

Supermarkets (Refrigeration & Freezing)

  • Medium and low-temperature display cases
  • Optimized for CO2 booster systems

CO2 compressors are widely used in supermarkets to ensure reliable cooling for fresh and frozen food, while reducing environmental impact.

Distribution Centers & Cold Storage Warehouses

  • Large-capacity refrigeration and freezing systems
  • Expanded capacity range through parallel compressor operation

For logistics and cold chain applications, CO2 refrigeration systems enable stable, scalable cooling performance for large facilities.

Food Processing Facilities

  • Cooling and freezing for production processes
  • Ideal alternative to HFC refrigerants

CO2 compressors support food safety and sustainability by providing efficient, natural refrigerant solutions for processing plants.

Hot Water Applications

  • Heat pump water heaters (Eco Cute systems)
  • Commercial hot water supply systems

CO2 compressors are also used in heat pump technology, delivering energy-efficient hot water solutions with low carbon emissions.
