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.
Why choose CO₂ as refrigerant?

Air Conditioning & Refrigeration Pressure Transmitters
Refrigeration pressure transmitters are used for commercial air-conditioning and for commercial and industrial refrigeration applications. They are made in stainless steel to be compatible with fluorinated and natural refrigerants and laser welding with no soft seals ensure hermetic tightness for decades.
KrioFrost Creates Russia’s Largest Transcritical CO2 Hypermarket System Using Danfoss Solutions
Globus had an ambitious target: to open the new 25,000 square meter hypermarket using transcritical CO2 for its refrigeration and heating. Danfoss helped KrioFrost—a Moscow-based refrigeration equipment producer and installer—to equip Globus’ huge new store in the Moscow suburb of Salaryevo with the company’s first transcritical CO2 booster refrigeration system.
Italy's largest hypermarket opts for CO₂ refrigeration
The use of transcritical CO₂ refrigeration in warm climates has been a hot topic for years. In Milan, the brand new 10,000 m² Iper market is a pioneer in CO₂ refrigeration using ejector technology to enhance efficiency in temperatures up to 38 °C.
CO₂ energy efficiency in supermarkets
Interest in carbon dioxide (CO₂) as a refrigerant in food retail applications has never been more intense than it is today and as such, there has been a lot of discussion with regards to the energy efficiency of these systems. The energy discussion is focused on two factors: climate change performance and financial justification.
