UTA – Gastight shut-off damper

• For shut-off and balancing of air intake and exhaust ducts
• A closed damper fulfils the requirement of leakage class 3 (EN1751:2014) for size ≥ 300×300 mm (stainless steel seals) and for size ≥ 150×150 mm (silicon seals)
• Classification of casing leakage (EN1751:2014) class C
• The outer frame of galvanized, painted or stainless steel. Blades of galvanized or stainless steel with double sheet construction. Blades contain stainless steel spring seals for low leakage. Silicon sealing as an option
• Earthing stud as standard
• Electrical, pneumatical or manual operation system available
• UTA dampers can be supplied with connection pieces for round duct
• Maximum duct pressure for damper construction 5000 Pa and maximum air velocity of 15 m/s
• The normal operating temperature for the damper is from -50 ºC to +80 ºC. Actuator and component selection can affect this temperature range. Other temperatures available on request
• Available as ATEX certified
• SIL 2 safety assessment certificate available for the damper on specific terms

Halton UTA 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 UTA is used as a shut-off, gas and balancing damper in applications where tightness and reliability are important.

UTA dampers meet international standards for both rectangular (width B 100-1200 mm with 25 mm division and height H 100-1600 mm with 50 mm division) and circular ducts (Ø200-1250 mm). Modular constructions up to 2500×2600 mm available. For bigger sizes, contact Halton Marine.
Non-standard dimensions and flange drilling available on request. Standard flanges and drilling according to ISO 15138 standards. Frame thickness 3 or 5 mm. Blades are made of two sheets, each of them being 1 mm thick (sandwich design).
