New EX3 electronic expansion valve launched

Emerson Climate Technologies Flow Controls, a business unit of Emerson, launched its new EX3 electronic expansion valve. The EX3 is a stepper-motor driven electronic expansion valve that provides precise mass flow control and high energy efficiency for supermarket showcases and cold rooms with multiple parallel evaporators. The EX3 was recognised with an honourable mention in the refrigeration category of the 2015 AHR Expo Innovation Awards competition sponsored by ASHRAE, AHRI and the AHR Expo.

The EX3 has an integrated solenoid mechanism allowing it to shut off the refrigerant line automatically in case of power interruption without requiring an external battery or any other energy-storing devices. The IP67 rating of EX3 ensures excellent performance even under the most severe working conditions, while the unique valve body design provides the benefits of easy on-site commissioning, maintenance and service. In contrast, conventional thermal expansion valves are sensitive to the load changes that occur seasonally.

The EX3 is designed as a compliment to the Dixell™ electronic controller, although it will work with controllers from other manufacturers. The combination of the EX3 and the Dixell controller provides a complete integrated and intelligent solution to maximise system energy-savings.
