The A-60 Fire Damper is Slimmer Than All Others


Published Oct 11, 2018 8:30 AM by Delta "T" Systems

Most marine fire dampers don't take bulkhead and deck thicknesses into consideration. This means that naval architects, marine engineers and commercial boatbuilders typically have to modify their plans to accommodate this limitation. Delta "T" Systems' Slimline A-60 Rated Marine Fire Damper is a mere 4.25" deep. The thinnest on the market, it provides serious design adaptability, whether the project is a refit or newbuild.

Made in the USA of 100 percent marine grade 316 stainless steel, the Slimline A-60 damper comes in 56 standard sizes and unlimited custom dimensions of up to 46.75 inches square. With stronger and thicker materials than the competition, it is USCG approved for use in penetrating Class A-0, A-15, A-30 and A-60 bulkheads and decks. It is also Wheelmark certified under EU Marine Equipment Directive (MED) and complies with Subchapter M.

The Slimline A-60 Rated Marine Fire Damper delivers absolute failsafe operation. Its CE-approved electric actuator is powered by 24–240 VAC or 24–125 VDC and is housed in a NEMA IP54 ZP Type 2 enclosure. In the event that the temperature rises above 165° F, the separately-mounted, manually-resettable heat sensor triggers the actuator to automatically close the damper. The actuator delivers 180 inch-pounds of closing torque to its overlapping blades with an independent, patented locking mechanism that only engages in the case of a true fire event. 

A test switch is mounted above the temperature sensor. This allows the ship's engineer or USCG inspector to test the operation of the damper.
