Refra » CO2 Systems
CO2 refrigeration systems are an environmentally sustainable solution that use carbon dioxide (R744) as a natural refrigerant, offering low global warming potential and high efficiency. Refra specializes in producing both transcritical and subcritical CO2 systems, tailored for a range of industrial and commercial applications.
The benefits of CO2 refrigeration system include energy efficiency, reduced greenhouse gas emissions, compliance with evolving environmental regulations, and a long-term cost advantage. Additionally, CO2 systems provide both versatility and safety, as they are adaptable to various climates and suitable for a wide range of applications. The non-flammable and non-toxic properties enhance safety by reducing incident risk and simplifying maintenance.
GREEN SOLUTIONS | The systems are made using low GWP solutions that have better efficiencies and capacities, as well as less environmental damage.
CO2 transcritical refrigeration systems are versatile and capable of addressing diverse cooling requirements within a single system. CO2 systems can be configured to deliver either low or medium temperature cooling efficiently, with an evaporation temperature reaching as low as -20°C. Alternatively, they can be integrated into a booster system that provides both low and medium temperature cooling simultaneously, with an evaporation temperature as low as -50°C. These systems operate effectively in ambient temperatures from +10°C to +35°C and efficiently utilize the heat generated during the cooling process for additional heating purposes.
Subcritical CO2 refrigeration systems are designed to function efficiently in lower ambient temperatures, ranging from -10°C to +15°C. Utilizing CO2 in its subcritical state and maintaining high performance with lower pressures and temperatures, these systems are ideal for cold storage and industrial cooling. Subcritical CO2 systems offer significant energy savings and reliable performance compared to traditional refrigeration systems, particularly in regions with stable, cooler temperatures. When designed as a cascade system, using a combination of CO2 and Propylene refrigerants, the unit is able to achieve low cooling temperatures and maintain high coefficient of performance (COP), even under higher ambient temperatures. This makes the system particularly effective in warmer regions, where traditional refrigeration systems struggle with energy efficiency.
CO2 refrigeration systems have gained widespread popularity as a sustainable solution in the air conditioning and refrigeration industries for their energy efficiency and environmentally friendly characteristics. Refra has been producing both transcritical and subcritical CO2 refrigeration systems for over 10 years, providing the expertise and experience needed to deliver high-quality products.
In the retail industry, CO2 refrigeration systems are commonly installed in supermarkets, grocery stores, gas stations and other retail environments where maintaining optimal conditions for fresh and frozen goods is a must. These systems provide precise and consistent temperature control to ensure food quality and safety. Retailers choose CO2 systems because of their energy efficiency, as they reduce operational costs, especially in large, high-traffic environments that demand constant cooling.
In the industrial sector, R744 refrigeration systems are widely adopted in large-scale cooling processes, such as in food processing plants, cold storage facilities, and breweries. These systems offer superior temperature control and robust performance, leveraging the high heat transfer properties of CO2 and its ability to operate effectively in low-temperature settings. Industrial users benefit from the durability, energy savings, and lower environmental impact of CO2, making it an ideal choice for industries with rigorous cooling demands.
The versatility of CO2 refrigeration systems allows them to be adapted for various climates. Serving both commercial and industrial sectors, Refra’s CO2 systems are designed to meet a wide range of cooling capacities and applications. Refra offers tailored solutions with R744 refrigerant, ensuring that each system is customized to the specific needs of the customer.
