CO₂ in Industrial Refrigeration

  • CO₂ solutions for Industrial Refrigeration - Danfoss
  • Industrial refrigeration is the first area where CO2 has made a successful comeback. CO2 in industrial refrigeration is used either as the low-stage refrigerant in cascade installations, or as a secondary coolant. Danfoss has more than 15 years of experience in developing components for sub-critical CO2 systems and offers a complete range of valves for those applications, including: 

     

    • Control valves 
    • Line components 
    • Complete valve stations 
    • Filter-driers 
    • Sensors (temperature, pressure, level, gas detectors) 

     

    Danfoss has carried out all the required tests to ensure that components released for use with CO2 are compatible in all respects. Danfoss industrial refrigeration specialists can help you with the selection of the right components for CO2 applications.

    We have developed a number of tools that facilitate design of CO2 systems such as DIRcalc™ software, application guides and a comprehensive set of technical leaflets and instructions.

    Pumped CO2 Solutions
    By investing in a CO2 secondary cooling system today, you protect yourself from ever-increasing energy prices over the next 10-15 years!

    Research has shown that an average installation of a refrigeration system using CO2 as a fluid is no more expensive than a system installed using a water-based brine/glycol.

    For an experienced installation com­pany it can be cheaper to do a 500 kW refrigeration installation for cold storage using CO2 than a water-based secondary cooling system. Examples have shown that savings on the instal­lation can be up to 12% by using a CO2 based refrigeration system.

    At Danfoss, we offer a wide range of valves and controls for both ammonia and CO2 in secondary cooling and cascade applications, including award-winning ICF Control Solution and ICM Control Valves, and also new unique control solutions for pumped CO2 with AKV Electronic Expansion valves.
