Catalogue excerpts

Halton FDB2 fire dampers are type-approved class A0(A60) fire and gas dampers for use in offshore, marine and navy ventilation systems. The FDB2 can be installed in rectangular or circular ducts. All fire dampers have a fusible link and they prevent the spread of fire and gases within the ventilation ductwork. When the blades are 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. Fire dampers with non-standard dimensions can be supplied on request. • Type-approved by most recognized classification societies: class A0 without insulation, A15-A60 when suitably insulated • Available as ATEX certified • Shock tested • Blades contain silicone seals (effective up to 300 °C) for low leakage in normal conditions and thermal expansion graphite seals (effective from 150 °C) to increase tightness even up to 50% in a case of fire. Closed damper fulfills the requirement of leakage from class 1 to class 3 depending on size. Details available from Halton Marine. • Nominal fuse release temperature 50 °C, 74 °C or 100 °C. Other temperatures available. • Low weight due to patented double skin blade structure • Automatic electrical, pneumatic or spring operation system available • Maximum duct pressure for damper construction 5000 Pa and maximum air velocity 15 m/s Halton MARINE
