CCMT - a valve with versatile functionalities in transcritical CO2 systems
The CCMT is a highly reliable electric pressure regulating valve optimized for transcritical CO₂ refrigeration. The valve has versatile applications in the transcritical system. First, the valve is capable of high pressure gas cooler control (transcritical). Second, the CCMT can be used as gas by-pass valve (medium pressure control). If desired, the valve can also be used as a normal expansion valve for evaporators (does not apply to CCMT Light – verification tests in progress), or as an electric pressure regulating valve in the suction line.

CCMT Light
The CCMT Light is the latest addition to our CO2 portfolio. The valve is robust, accurate and easy-to-use and focuses on stress-free valve installation and field service. It is designed to have a high tolerance for dirt and debris which reduces service-related incidences and improves long-term system reliability. Installation time is decreased because the valve is delivered in open position – this means it is ready for welding / brazing which lowers production costs and increases productivity.
CCMT 16-42
With the CCMT 16-42 electric regulating valve for transcritical CO2 applications, you get a fully serviceable three-in-one solution with a valve, transmitter and filter integrated into one, compact unit. The cartridge design of the component means that all functional parts are easy to service and replace – not even the orifice remains in the housing when the valve is dissembled. When you exchange the cartridge, you get a brand new valve. At the same time, the integration of valve, transmitter and filter into one unit also allows for easy installation with fewer connections and thus reduced risk of leakage. The valve comes with solder/brazing and weld connections to make it fit in any system.
A perfect fit for all CO2 refrigeration systems
The complete CCMT range covers CO2 refrigeration systems of all types sizes – from very small applications to large systems. The CCMT Light is optimum for condensing units or small packs up to 100kW and the CCMT 16-42 for medium to large packs from 100kW up to 600kW.
