Marine Electrical Fire Damper

Marine Electrical Fire Damper

1. Introduction:

Designed for use in offshore applications to protect the integrity of fire rated bulkheads and decks.

Each damper is controlled by an electrical failsafe spring return actuator combined with a thermoelectric tripping device (thermal fuse) and volt free contacts for remote status indication.

2. Configuration Options:

		Features
Explosion-proof requirements	Explosion-proof/non-explosion-proof	User defined
Body Color	Red (standard)	User defined
Type	Airtight: Rectangular Non-airtight: Rectangular/Round	User defined
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.
Fire Resistance Rating	A0/A15/A30/A60	Within 0/15/30/60 minutes, the average temperature on the backfire side shall not be higher than the original temperature by more than 140 degrees, and the temperature at any point including the joint shall not be higher than the original temperature by more than 180 degrees.
Control Unit	Electric Actuator	It can be manually operated on-site and can be controlled remotely.
Spindle material	Stainless steel	It has a series of characteristics such as excellent corrosion resistance, formability, compatibility and toughness

3. Specific Difference Between Us and Other Suppliers:

Control voltage DC24V/AC220V/AC110V is supplied, the fire damper should normal open and close on outage.

Central control room can cut off the electric source to close the fire damper in emergency, and reconnect the power to open the fire damper again;

If the temperature of air within damper duct exceeds 70±3℃ or outside air temperature around duct near 95℃, the fusible link damper will be broken to close the fire damper;

On/off signal output when the fire damper is open/close.

Each fire damper is supplied with one electrical control box to control on/off operation of the fire damper locally or remotely.

5. Installation:

The fire damper is suitable for the air duct of the ventilation and air conditioning system with fire protection requirements.

In case of fire, once the temperature in the air duct rises to more than 70℃, the fire damper automatically closes quickly

to achieve regional isolation and prevent the fire from spreading along the air duct.

6. Trouble Shooting:

Problem	Recommended action
The blade switch is not in place	1. Do a good job of monthly inspection work, the switch is not in place handle, activating the damper, to the shaft refueling. 2. Remove damper parts in important areas for thorough cleaning 3. Further method, when the new platform is built, the refueling nozzle at rotating shaft is added for easy maintenance
