Specification
Halton FDL fire dampers are type-approved classA0(A60) fire dampers for use in offshore, marine and navy ventilation systems. The FDL can be installed in rectangular or circular ducts. The FDL dampers are used to prevent the spread of fire within the ventilation ductwork. All fire dampers have a fusible link and spring return actuator. When the blades are in the open position, the device does not cause significant pressure loss 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 also be supplied on request.
Dimensions
The Halton FDL fire dampers are manufactured according to international standards for both rectangular (width B 100-1300 mm and height H 100-1200 mm, 1 mm division) and circular ducts (Ø100-1250 mm). Modular constructions are available for bigger sizes. Non-standard dimensions and flange drilling are available on request.
Standard flange width 27 mm. Flanges and drilling also available according to ISO 15138 standards.
Blades are made of two sheets, each of them being 1 mm thick (sandwich design).
Modular construction sizes up to 2660×2460 mm.
Frame material thickness 3 mm or 3-5 mm according to SOLAS.

Product Models and Accessories
Halton FDL is available with following actuators:
- FDL-EL: Electrical spring return motor; standard actuators being 24 V or 230 V or 120 V. The motor contains built-in open-closed limit switches. Separate junction box included in the EL-model. A wide range of Ex actuators available, including a one second closing time function as an option.
- FDL-PNR: Pneumatic rotating actuator.
- FDL-SP: Manual spring-actuated damper with fusible link.
DOT: manual override function available for PNR and EL models.
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.
Operation Principles
In the event of a temperature rise in ductwork:
- FDL-EL: fusible link releases and cuts off operating voltage to the spring return motor, allowing the spring to close the damper blades. The fire damper opens automatically when the fuse has been changed and the operating voltage to the motor is re-established.
- FDL-PNR: fusible link releases and cuts off operating pressure to the spring return actuator, allowing springs to close the damper blades. The fire damper opens automatically when the fuse has been changed and the pneumatic air supply is re-established.
- FDL-SP: fusible link releases allowing the spring to close the damper blades. When the fuse has been changed, the fire damper must be reset into open position manually.
