Ship Electrical Fire Damper

Ship Electrical Fire Damper

1. Product Introduction:

Usually it is open, the angle of blade is adjustable at the range of 0 degree to 90 degrees manually, once fire occurs, the gas temperature of duct arrives at 70 degrees, and then the fuse protector will be fused and the damper will close under the pull of spring. Compared with the ordinary fire proof damper, it also can be closed by DC24V electrical control. It is applied to the pipeline of smoke extraction which needs fireproofing. It can isolate smoke’s leaking and stop the fire spreading.

2. Configuration Options:

		Features
Shape	Round	User defined
	Rectangle	User defined
Explosion-proof Requirements	Explosion-proof	For use in hazardous areas, containing explosive gases
	Non-explosion proof	It is installed on the air duct of the ventilation and air-conditioning system with fire protection requirements.
Material	Carbon steel	Higher hardness and better wear resistance can be obtained after heat treatment. The hardness in the annealed state is very moderate, and it also has good machinability. Raw materials are very common, simple and easy to obtain, and the production cost is relatively low.
Fire Resistance Rating	A0/A15/A30/A60	User defined
Control Unit	Electric Actuator	It can be manually operated on-site and can be controlled remotely.
Control Mode	Local/Remote/Central Control	User defined
Level of Protection	IP54/IP66	User defined
Valve Body Colour	Red(standard)	User defined

3. Specific Difference Between Us and Other Suppliers:

Comparison
Product Picture of other low quality supplier		Product Picture of our factory
Other low quality supplier	Consequence	Our Factory	Consequence
The thickness of the damper shell does not meet the requirements	The casing is prone to breakage	The thickness selection of the damper shell The regulations of each classification society are consistent with the SLOAS requirements	The shell meets the requirements, and the damper can be used for a longer time
The fire rating does not meet the requirements	It is easy to leave a safety hazard	Select as required	Product use more assured, longer service life
The installation accuracy of the connecting rod between the baffles is not enough	As a result, when the fire damper is closed, the shutter still cannot be completely closed.	The connecting rod between the baffles is installed with high precision	When the fire damper is closed, the shutter can be fully closed.
Air leakage does not meet the requirements	Excessive air leakage from fire dampers will cause major safety hazards	Airtight performance is selected according to requirements	The air leakage meets the requirements, and the product is safer to use

4. Features:

Using galvanized steel as material to make sure good insulation performance, fire & corrosion resistance.

Duration, long service life.

Easy installation.

The flange is bended directly by the frame.

The valve size and color can be customized according to customer's requirements.

6. When arranging fire dampers, pay attention to:
1. The height of the installation location is generally controlled at about 1.5m. If the height exceeds 2m, rope traction should be used.
2. When using a wire zipper, the length is required to be less than 6m, the number of bends is less than 3, the bending radius is greater than 300mm, and the steel pipe is used as a sheath to protect the rope.
3. The fire damper is arranged in the dangerous area, the remote control solenoid valve should be placed in the safe area together with the control box, and the remote control device is 1.5m away from the ground.
4. The control of the fire damper (marine fire damper) on the kitchen exhaust duct should be interlocked with the release of carbon dioxide, and the control box should be placed near the kitchen door.
5. The tuyere baffle of the emergency generator room should be interlocked with the start of the generator diesel engine. According to ISO requirements, usually the fire damper in the emergency generator room adopts the form of non-failure closing.
