Product Overview

Space limits aren’t an obstacle for our CFR terminal units. Available in a range from 100 to 4,600 CFM, this heating and cooling system offers our commercial clients tremendous flexibility to meet a wide variety of HVAC system design requirements. The series flow fan units are specifically designed for 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. CFR 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.
