NEWS Hosts Danfoss Webinar on Electronic Expansion Valves

Free Webinar Will Take Place on Nov. 21

TROY, Mich. — The NEWS, in conjunction with Danfoss, will host a free webinar titled, “The Ins and Outs of Working with Electronic Expansion Valves,” at 1 p.m. ET on Nov. 21.

The webinar, hosted by Jeff Staub, applications engineering manager, Danfoss, will help field-service technicians gain a better understanding of the function and operation of, as well as key troubleshooting strategies for, stepper motor and pulse-width-modulating electronic expansion valves. Participants will learn how adaptive control achieves optimal minimal superheat and what the difference is between a mechanical and electronic expansion valve in superheat control and capacity selection.

After participating in this webinar, attendees will be able to define how expansion valves function in a refrigeration cycle, including how mechanical expansion valves differ from electronic expansion valves; determine methods for correcting superheat to achieve optimum evaporator efficiency; select the proper expansion valve based on the application and system conditions; differentiate various superheat controllers; and be able to define an appropriate system configuration based on application parameters and required control modes.
