In sectors such as the food industry, the use of CO2 as a refrigerant – carbon dioxide, also known as R744 – with its many technological variants, represents a long-term solution, as it is a natural refrigerant with a minimum GWP.

At GC, we have developed our range of evaporators and condensers to work with CO2 with PS45, PS60 and PS80, in line with our commitment to environmental responsibility.

The benefits of CO2 as a refrigerant include:

• Efficient: It offers high heat transfer coefficients and high thermal conductivity.
• Clean: CO2 is a natural, clean and environmentally friendly refrigerant.
• Safe: CO₂ is non-corrosive, non-flammable and non-toxic.
• Economical: the cost of production is low, making it a safe and inexpensive alternative for refrigeration.
• The low viscosity of the liquid and gas lines allows for the use of smaller piping, thereby reducing system costs.
• Excellent cooling properties: high volumetric cooling capacity (6 times higher than R404A), resulting in smaller compressors, components and piping. In addition, its constant evaporating temperature character makes it possible to use it with a smaller temperature difference in evaporators and heat exchangers. The result is much lower energy consumption
• High cascade efficiency: performs well in cascade systems, offering excellent efficiency and performance values with low temperature systems.

At GC we are committed to innovation and sustainability.
