Discover the opportunities of CO₂ refrigeration

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 transcritical and subcritical 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. Meanwhile, alongside the traditional large applications, CO2 is increasingly being used in a broader range of settings than ever, including very small systems.
