Catalogue excerpts

Halton FDD fire dampers are type-approved class A0(A60) fire dampers for use in marine and offshore ventilation systems. The FDD can be installed in circular ducts. All fire dampers have a fusible link and they prevent the spread of fire and gases within the ventilation ductwork. When the blade is in the open position, the device does not cause significant pressure loss, noise or flow disturbance. Fire dampers are set from outside and can be installed in any position. An open-closed indicator is visible on the outside of the damper. • Type-approved by most recognized classification societies, class A0 - A60 fire and gas damper when suitably insulated • Fixed frame of painted, galvanized or stainless steel. Blades stainless steel. Flanges available as an option. • Blade contains glass fibre seals (effective up to 300 °C) and thermal expansion graphite seals (effective from 150 °C) • Nominal fuse release temperature 50 °C, 74 °C or 100 °C. Other temperatures available. • Very low leakage • Automatic electrical, pneumatic or spring operation system available • Maximum duct pressure for damper construction 5000 Pa and maximum air velocity 15 m/s. In case of high duct pressure, contact Halton Marine for finding the most suitable solution. Halton MARINE
