    Product Overview

    Available in a performance range from 100 to 4,100 CFM, ENVIRO-TEC Parallel-Flow Fan-Powered variable air volume (VAV) terminals can meet your commercial heating and cooling needs while fulfilling a multitude of system design requirements. These terminals are specifically designed for quiet operation and offer improved space comfort and flexibility for a wide variety of heating, ventilating, and air-conditioning (HVAC) systems. And because our VAV units offer superior airflow measuring and recover waste heat, you can save on energy costs while keeping building occupants comfortable. Fan-powered VAV terminals are a popular choice for heating and cooling perimeter zones because the terminal recovers heat from lights and core areas to offset heating loads in those zones. Additional heat is available at the terminal unit using electric, steam, or hot-water heating coils. You can also use these controls to energize remote heating devices such as wall fins, fan coils, radiant panels, and roof load plenum unit heaters.
