Functions

Fire damper mainly used on the ventilation duct needs fireproof requirement. Once the fire happened, the temperature inner the duct increased to 70℃, the fire damper will close automatically, thus can prevent the fire spreading from the duct. Control type, rotary cylinder.

Advantages

Fire damper adopts exclusive frock designing and production, with small deflection, low air leakage, high stability. Equips relative signal feedback, can control automatically.

· fusing temperature 70±3℃,

· close time : <2S,

· air leakage ≤5m3/m2·h,

· fireproof grade : A0~A60;

· Control power : DC24V/AC110V/AC220V,50/60Hz,

· Protection grade :  IP44/IP56,

· EX-proof grade : ExdIIBT4/ExdIICT4,

· fire-proof grade  : A0~A60;

 

It was broadly used on passenger vessel, cargo ship, warship and offshore platform ducts.
