DunAn Microstaq Inc. earned the top honor in the Refrigeration & Ice Machines category of the 2015 Dealer Design Awards, thanks to its MSEV USHC Retrofit Kit.
The MSEV and USHC Kit includes a Modular Silicon Expansion Valve (MSEV), Universal Superheat Controller (USHC), and a wiring harness. The MSEV is an electronically controlled expansion valve that functions as a responding expansion device for HVAC and refrigeration applications with up to 6 ton of cooling capacity. The USHC is a device used to drive and modulate the MSEV to maintain a desired superheat target for a multitude of refrigerants. It consists of a MEMS pressure sensor, external thermistor, and a micro-processing unit. The wiring harness is used to connect the MSEV and USHC.
