DunAn Microstaq, Inc. (DMQ), a MEMS technology company dedicated to advancing flow control solutions primarily for the HVAC, refrigeration and automotive industries, announces the expansion of its family of Modular Silicon Expansion Valves (MSEV) to include cooling capacities of 6, 7 and 8 tons (R-410a). Together with the High Capacity MSEV (HC-MSEV) valve family, these new valves complete the range of cooling capacities from sub-1 ton to 25 tons and deliver all the benefits of the current Modular Silicon Expansion Valve (MSEV) to systems with larger cooling capacities.
The MSEV is an electronically controlled, normally closed and one directional flow valve. It can be used for refrigerant mass flow control in today’s industry-standard HVAC and refrigeration systems. The MSEV provides precise superheat control and quick mass flow adjustments through a closed loop control methodology achieved with DMQ’s Universal SuperHeat Controller (USHC). Embedded with the newest generation of MEMS chip, silQflo® Silicon Servo Valve (SSV), the MSEV is the fastest responding refrigerant expansion valve in the industry.
Customers seeking to improve refrigeration system performance were the drivers for expansion of this family of valves with higher cooling capacities. Paired with the USHC preprogrammed for multiple refrigerants, all DMQ valves provide customers a “plug and play” option for a less costly, fast path to an electronic closed loop control solution specific to their application. The fast response of the valves makes them ideal for improving performance across a now wider range of refrigeration system capacities.
