Our range of marine dampers are designed and build to meet the IMO FTP Code and SOLAS 74

We offered 3 range of fire dampers

1. A60 Motorized Marine Fire Damper (Aerodynamic Blades)
2. Manual/Electrical Marine Fire Damper
3. Manual Marine Fire Damper

The most significant characteristics of our Marine Type Fire Damper is that it comes with an electrical actuator, which enables rapid closing of the damper blade when an electric signal is sent. Once the damper blade is shut, the control system will send a message to inform the control tower. The Marine Fire Damper can be operated in three ways, the manual operation mode, the electrical operation mode and activation by thermal fuse unit.

OPERATION METHOD

The damper is fitted with an electrical actuator which enables rapid closing of the damper blades. It can be operated in three ways.

[1]	MANUAL OPERATION MODE
	[ Closing ] Pull the MANUAL LEVER. This actuates the spring to release(ADS-B101) causing the damper blades to close momentarily. ¡¡ Closed [ Reset ] Turn the MANUAL HANDLE counterclockwise until the indicator reaches position "O" on the scale, locking the damper blades. ¡¡ Reset
[2]	ELECTRICAL OPERATION MODE
	The electrical actuator closes/opens the damper blades rapidly once signal (DC 24V) is received from control centre. Once the damper is closed/opened, confirmation signal and reporting signal will be sent out immediately at any time.
[3]	ACTIVATION BY THERMAL FUSE UNIT
	A temperature above 72 °C in the damper duct causes the temperature fuse to be melt. The shaft of the fusible link, in turn, unlock the fuse arm to activate the spring in the ADS-B101, thus causing the damper blades to close momentarily.
