Headquartered in Austin, Texas, DunAn Microstaq, Inc. (DMQ), dedicated to advancing flow control solutions for the HVAC, refrigeration and automotive industries, recently announced the release of the High Capacity Modular Silicon Expansion Valve (HC-MSEV). This new valve is a fast-responding refrigerant expansion valve for the HVAC and refrigeration industry for 6 ton to 16 tons (R-410a) cooling capacities. The HC-MSEV brings all the benefits of the existing Modular Silicon Expansion Valve (MSEV) to systems with larger cooling capacities.
The HC-MSEV prototype is an electronically controlled, normally closed and one directional flow valve. It can be used for refrigerant mass flow control for today’s industry-standard HVAC and Refrigeration systems. The HC-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 HC-MSEV is among the fastest responding refrigerant expansion valve in the industry.
