Small CO₂ systems more affordable with CCMT high-pressure valves by Danfoss

In the food retail industry, CO₂ refrigeration systems help supermarkets reduce their overall environmental impact and their refrigeration lifecycle costs. For smaller retailer operators, such as convenience stores and gas stations, large CO₂ refrigeration systems are normally not a cost-effective investment. However, Danfoss’ CCMT high-pressure valve supports smaller transcritical CO₂ refrigeration systems to be now affordable, easy to operate, and safe.

High-pressure control for smaller systems

The CCMT high-pressure valve is designed for smaller transcritical CO₂ racks with a capacity up to around 100 kW. A cost-effective alternative to the ICMTS high-pressure expansion valve for large refrigeration systems, the CCMT valve functions as:

• High-pressure control valve
• Gas cooler control valve
• Gas-bypass valve for intermediate/receiver control
• Expansion and suction modulating valve in CO₂ systems

Safe and easy to use

Designed to work together with the pack controller, the CCMT’s clever cartridge design makes it easy to plug into the system. If dirt in the strainer or faulty wiring is an issue, the CCMT is easy to clean or replace, which helps keep system downtime to an absolute minimum. With a maximum working pressure of 140 bar and a burst pressure over 700 bar, the CCMT is designed and tested to meet high safety standards. The combi-connections give users the choice of either brazing or welding the valve in the application. Moreover, it features a patented cone design, which makes the CCMT valve pressure stabile in the whole pressure range.

Made from rigid stainless steel, the CCMT meets EN 12284 safety design standards and is produced on TS 16949 compliant production facilities. The CCMT can also be used in heat pumps.
