Carnes Terminal units and VAV box offer a precise control of the flow and temperature for maximum occupant comfort.
They are designed for low pressure drop and sound level. Certified by AHRI
Single Duct Terminal Units
The Carnes Model AV is available as a basic control unit with open-end discharge or with an optional sound attenuator module. This unit offers low-pressure drop, low sound levels, and valve characteristics, which create stable control conditions within the conditioned space.
Dual Duct Terminal Units
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.
Model ADCC – With or Without Mixing
The Carnes Model ADCD 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 constant discharge volume control. (See ADCC design for adjustable mixing and no mixing 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.
Rétrofit Terminal Units
The Carnes Model AR replaces a short section of duct ahead of an existing terminal unit. The system with constant volume reheat terminal units can be easily converted to variable air volume by adding a retrofit unit upstream of the existing terminal unit which can now serve as a sound attenuator. The internal damper of the existing terminal unit should be removed, or placed in the full open position. This allows the existing terminal unit to act as a sound attenuator. The pneumatic thermostat, which formerly activated the reheat coil, can now be used to control the AR unit and the existing coil when required. There is no insulation in contact with the air stream. This product is ideal for Hospitals, Labs, Schools, and Government Buildings, i.e., anywhere where Indoor Air Quality (IAQ) concerns exist.
