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.

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

Our Factory
|
Consequence |
|
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 |
|
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. |
|
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 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 |
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 |
