The ExV family valves, together with their control systems, represent the first example in the world of using sophisticated stepper motor technology in refrigeration applications.
CAREL has scaled down the size, capacity and price of technology that was already used in medium and high capacity air-conditioning systems (hundreds of kW). The result is the introduction of a reliable high-tech product into a market dominated by mechanical expansion systems. Compared to the latter, ExV valves provide fine control and optimisation of evaporator operation and lower superheat, prevent temperature swings, reach steady operation much faster, and above all bring enormous benefits in terms of maximising efficiency
