DunAn Microstaq, Inc. (DMQ), which is based in Austin, Texas, is introducing the production version of its High Capacity Modular Silicon Expansion Valve (HC-MSEV). The valve is a fast responding refrigerant expansion valve that aims to provide precise superheat control for the commercial HVAC and refrigeration industry.
The production HC-MSEV now has a broader range of cooling capacity from 10 to 25 tons (R-410A). Its packaging design aims to achieve multiple cooling capacities through the use of spool cartridges within the same size valve housing. The new forged valve housing is now 50 per cent less in weight compared to the prototype version. This has brought the overall cost of the product to a competitive pricing level.
