Product Overview
What sets our CRQ terminal units apart from the competition? They offer our commercial clients tremendous flexibility to meet a wide variety of HVAC system design requirements—and create a layout that works in any space. Available in a range from 100 to 4,400 CFM, the CRQ series flow fan units are specifically designed for ultra-quiet operation and offer improved space comfort. Due to rising interest in indoor air quality, many HVAC system designers are focusing on the effects of particulate contamination within a building’s occupied space—HVAC system noise is often overlooked as a source of occupied space contamination. By utilizing an integrated sound attenuator, CRQ terminals are specifically designed to prevent obtrusive fan noise from reaching building occupants while providing constant air motion in the space. The VAV terminal recovers heat from lights and core areas to offset heating loads in perimeter zones. Additional heat is available at the terminal unit using electric or hot-water heating coils. Controls are available to energize remote heating devices such as wall fins, fan coils, radiant panels, and roof load plenum unit heaters.
