Specification

Halton UTG dampers are used to shut-off and balance airflow rates in high pressure ductworks. Dampers meet international standards for rectangular and round ducts. In the open position, the blades face the direction of flow and do not cause a significant pressure loss. The UTG is used as a shut-off, gas and balancing damper in applications where tightness and reliability are important.

Dimensions and Material Thickness

UTG shut-off, gas and balancing dampers meet international standards for both rectangular (width B 100-1200 mm and height H 100-1600 mm, 1 mm division) and circular ducts (Ø100-1250 mm). Non-standard dimensions are available on request. Standard flange width 27 mm. Flanges and drilling also available according to ISO 15138 standards. Modular construction sizes available up to 2400X3200 mm. Frame thicknesses from 3 mm to 10 mm. Standard frame thickness is 3 mm. Blades are made of two sheets, each of them being 1 mm thick (sandwich design).

Product Models

Halton UTG is available with following actuators:

• UTG-EL: Electrical spring return actuator; standard actuators being 24 VAC/DC or  230 VAC or 120 VAC. Depending on the choice of actuator, the actuator might contain built-in open-closed limit switches. A wide range of Ex actuators available, including a one second closing time function as an option (for limited sizes).
• UTG-PNR: Pneumatic rotating actuator
• UTG-MAN: Manual handle

HSO: Halton Smart Override function for HVAC damper black-start available for PNR and EL models. With automatic reset function when power and/or pneumatic air supply is reinstated.
A wide range of accessories available.
