CO2 Refrigeration Systems

CO2 refrigeration systems are a sustainable cooling choice that use R744 – a natural refrigerant with low global warming potential and high efficiency. Refra designs both transcritical and subcritical CO2 cooling systems for diverse commercial and industrial applications. These systems offer energy efficiency, reduced emissions, and compliance with environmental regulations and latest F-Gas regulations. Non-flammable and non-toxic, CO2 ensures safety while reducing maintenance complexity. Refra CO2 systems are fully customizable, adaptable to different climates, and built for long-term efficiency and reliability.

GREEN COOLING | Refra has over 10 years of experience in manufacturing sustainable refrigeration systems with natural refrigerants like R290, R744, and R1270, supporting the shift toward low-carbon cooling.

Transcritical CO2 Systems

CO2 transcritical refrigeration systems offer versatile solutions for diverse cooling needs. They can be configured to provide low or medium temperatures or combined in booster systems for simultaneous multi-temperature cooling. Designed to operate efficiently in ambient temperatures from +10°C to +35°C, these systems also recover and utilize heat generated during cooling for additional heating applications, enhancing overall energy efficiency.

Subcritical CO2 Systems

Subcritical CO2 refrigeration systems operate efficiently in ambient temperatures from -10°C to +15°C, using lower pressures and temperatures ideal for cold storage and industrial cooling. They offer energy savings and reliable performance compared to traditional systems. When combined with Propylene in cascade systems, they achieve low temperatures and high efficiency even in warmer climates, overcoming challenges faced by conventional refrigeration.

CO2 Refrigeration Solutions

Refra offers CO2 refrigeration solutions for both commercial and industrial applications, with systems tailored to various climates and cooling capacities. Commercial CO2 refrigeration systems, such as transcritical booster units, are widely used in supermarkets, grocery stores, and gas stations – ensuring stable temperature control for fresh and frozen goods while reducing energy costs. Industrial CO2 refrigeration systems, including subcritical and cascade setups, are ideal for food processing plants, cold storage warehouses, and pharmaceutical manufacturing, providing reliable low-temperature performance. Refra delivers durable, efficient and future-ready CO2 systems, widely recognized for their energy efficiency and reduced environmental impact.
