CCMT transcritical CO2 valve

  • Valve, transmitter and filter in one
  • Sizes: 16, 24, 30 and 42
  • Controls transcritical pressure up to 140 bar

Danfoss has extended its portfolio of CCMT electric regulating valves by introducing an integrated 3-in-1 solution for transcritical CO2 applications. The new product is a valve, transmitter and filter built into one unit, suitable for applications above 100kW.

The electric regulating valves of the refrigeration system are vital components to secure continuous and safe operation of the refrigeration system, thus eliminating food waste.

In a CO2 food retail system, the transcritical electric regulating valve is a crucial component that ensures optimum operation under varying ambient and heat recovery conditions. While the gas by-pass control valve is used to keep an optimum pressure in the liquid line.

Adhering to strict food safety and environmental demands

Danfoss’ CCMT electric regulating valve sizes 16, 24, 30 and 42 now offer an integrated solution with the valve, transmitter and filter built into one unit, allowing for better control during the high pressure transcritical and medium pressure by-pass stages. The reduced number of components eliminates the need for several connections, thereby decreasing the risk of refrigerant leakage and the need for frequent refrigerant filling.

CO2-optimised technology for food retail

Standard features and advantages

  • Integrates valve, transmitter and filter into one compact unit, reducing complexity of the refrigeration system
