Terminal Units > Dual Duct
The Carnes Model ADCC dual duct VAV unit contains two valves providing low-pressure drop and low sound level. Hot and cold duct valves are independently controlled. Throttling valves are installed in an attenuator mixing section for low noise and temperature mixing. Selections of proper controller spring ranges and pneumatic devices allow sequences of operation for adjustable mixing and no mixing applications. (See ADCD design for constant volume applications.) Hot and cold-throttling valves can be factory set for normally open or normally closed configurations. A wide range of available control sequences makes the Carnes dual inlet VAV unit acceptable to most energy saving system design.
