FDH H0(H120) fire and gas damper

FDH – H0(H120) Kaasutiivis palopelti

Halton FDH fire and gas damper – a tighter fire and gas damper.

Overview

  • Type approved by most recognized classification societies, class H0(H120) fire damper when suitably insulated. Pre-insulated H0(H60) with ceramic wool at the factory. H0(H120) with additional insulation on site. Blades insulated with ceramic wool
  • Blades contain stainless spring steel seals for low leakage in normal conditions and thermal expansion graphite seals (effective from 150 ºC) to seal the damper in case of fire
  • Closed damper fulfills the requirement of leakage class 3 (EN1751:2014) for size > 300×300 mm. Casing leakage class C
  • Fixed frame and blades of stainless steel
  • Available as ATEX certified on request
  • Nominal fuse release temperature 50 ºC, 74 ºC or 100 ºC. Other temperatures are available
  • With automatic electrical or pneumatic operation system
  • Maximum duct pressure for damper construction 5000 Pa and maximum air velocity 15 m/s

Specification

Halton FDH fire and gas dampers are type-approved class H0(H120) fire and gas dampers for use in offshore and onshore ventilation systems to protect the integrity of bulkheads and decks where they are penetrated by ventilation ducts. The FDH fire and gas dampers can be installed in rectangular or circular ducts. The dampers have a fusible link and they prevent the spread of fire and gases within the ventilation ductwork. When the blades are in an open position, the device does not cause significant pressure loss, noise or flow disturbance. An open-closed beacon is visible on the outside of the damper.

Dimensions and Material Thickness

The FDH fire dampers are manufactured for both rectangular (width B 200-1200 mm with 25 mm division and height H 200-1200 mm with 50 mm division) and circular ducts (Ø200-1250 mm).
Non-standard dimensions and flange drilling available on request. Standard flanges and drilling according to ISO 15138 standards.
Standard frame material thickness 3 mm for size < 600 mm and 5 mm for sizes over 600 mm. Blades are made of two sheets each of them being 1 mm thick. Blades are pre-insulated with ceramic wool.

Product Models and Accessories

Halton FDH is available with following actuators:

  • FDH-EL: Electrical spring return motor; standard actuators being 24 VAC/DC or 230 VAC or 120 VAC. Depending of the choice of actuator, the actuator might contain built-in open-closed limit switches. Separate junction box included in the EL-model. A wide range of ex-proof actuators available, including a one second closing time function as an option.
  • FDH-PNR: Pneumatic rotating actuator. Junction box available as an option.

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:

  • FDH-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.
  • FDH-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.
