Low-GWP refrigeration using carbon dioxide

CO₂ is fast becoming the preferred refrigerant in Food Retail applications and Danfoss is leading the way towards the adoption of CO₂. With the implementation of refrigerant regulations like the Kigali amendment to the Montreal Protocol (Global) and F-gas regulative (Europe), the quest for alternative solutions is accelerating even further and CO₂ is now recognized as the most viable and efficient solution among natural refrigerants in Food Retail applications.

Danfoss has pioneered CO₂ technologies for both trans-critical and sub-critical systems for more than ten years and has gained valuable experience from thousands of installations all over the world. The many installations have proved that CO₂ can be applied in supermarkets enabling both environmentally friendly and energy saving systems in all types of stores.
