CAREL has introduced a new electronic expansion valve with copper fittings designed for transcritical CO2 applications.

The goal of reducing the environmental impact of refrigerant gases has driven the development of a new generation of high-performance components, including the new E2V-CW high pressure valves.
Easy installation
The E2V-CW is installed by braze welding the special copper fittings, rather than the more complex and expensive welding techniques required for stainless steel. CAREL says this installation simplicity further lowers the barriers to the use of CO2, and allows OEMs of Hecu and Heos condensing units to optimise their line assembly processes using K65 copper pipes.

Energy efficiency
E2V-CW uses modulating equipercentile control, guaranteeing accuracy and a rapid response in the control of refrigeration systems. This feature is common across the entire range of CAREL ExV valves, and ensures extreme precision at low cooling capacities and a fast response to sudden variations in load at high capacities. It is said to be the only efficient solution for circuits with an extended range of modulation!

Resistance to extreme operating conditions
E2V-CW has a stainless steel filter supplied as standard and a wide range of hermetic stators is available, suitable for any type of installation. CAREL adds that, together, these guarantee the highest reliability for any application, even in extreme conditions.
