CO₂ Solutions

  • CO2 Solutions
  • 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 across six continents. 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.

    Danfoss continues to create new and more cost effective solutions, bringing new energy saving features to the market. The goal is always to increase return on investment without compromising quality in food retail refrigeration.
