Combines superior control resolution of a stepper-motor valve with automatic shut-off of a solenoid
St. Louis, November 19, 2014 – Emerson Climate Technologies Flow Controls, a business unit of Emerson (NYSE: EMR) today announced the launch of 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 recognized with an honorable 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 outstanding 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. System superheat settings and evaporator controls can fluctuate greatly during hot or cold outdoor conditions or changing case loads, negatively impacting energy efficiency and causing case temperature instability.
“The EX3 is another example of Emerson’s commitment to providing integrated solutions for energy saving applications in supermarkets and cold rooms,” noted Ed Blittschau, vice president of sales and marketing, Emerson Climate Technologies Flow Controls. “It maximizes energy savings and offers more reliable food storage capability.”
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 maximize system energy-savings.
