CO₂ (R744) Compressors for Commercial and Industrial Refrigeration

High-Efficiency CO₂ Compressors for Reliable Refrigeration Systems

CO₂ (R744) compressors are high-pressure compressors designed for environmentally friendly refrigeration systems using natural refrigerants.
Since launching CO₂ compressors in 2009, Carrier Japan (formerly Toshiba Carrier) has built a strong global track record, delivering nearly 500,000 units worldwide. Leveraging Toshiba’s advanced technology and manufacturing expertise, we offer high-performance CO₂ compressors that provide exceptional efficiency, reliability, and long-term performance for commercial and industrial refrigeration applications.
With proven field performance and continuous innovation, our compressors support a wide range of systems, including supermarket refrigeration, cold storage, and heat pump applications, enabling sustainable and energy-efficient refrigeration solutions.

Proven & Trusted CO₂ Compressor Technology

Carrier Japan has been supplying CO₂ (R744) compressors since 2009, expanding their use from water heating systems to commercial and industrial refrigeration.
With extensive experience and a strong track record in the field, our compressors provide stable and reliable operation in demanding environments, ensuring long service life and consistent performance, backed by Toshiba’s manufacturing technology and quality standards.

High-Pressure Design for CO₂ Refrigerant (R744)

CO₂ refrigerant requires compressors capable of operating under extremely high pressure (up to 14 MPa class).
Carrier Japan CO₂ compressors, developed with Toshiba’s engineering expertise, are engineered with a robust high-pressure casing and optimized internal structure, delivering:

• • Stable operation under high-pressure conditions
• • Reduced oil discharge
• • High durability and long operational life

This makes them ideal for transcritical and subcritical CO₂ refrigeration systems.

Compact Rotary CO₂ Compressor Design

Our rotary compressor technology enables compact and lightweight product design, making system integration easier and more flexible.
Key features include:

• • Vertical and horizontal configurations
• • Space-saving design for refrigeration units
• • Optimized layout flexibility for OEMs

These features help customers design more efficient and compact refrigeration systems.

Scalable Refrigeration Systems with Parallel Operation

Carrier Japan CO₂ compressors, supported by Toshiba’s engineering expertise, support parallel operation using models with balance pipes.
This allows:

• Flexible system capacity design
• Improved redundancy and reliability
• Efficient system scalability

Parallel compressor systems are widely used in supermarket refrigeration, cold storage, and industrial CO₂ (R744) refrigeration applications.
