Delta “T” Systems’ A-60 Rated Round Fire Dampers have been designed specifically for marine applications. Available in standard and custom sizes ranging from 12 inches to 36 inches (305 mm to 914mm) in diameter with either electric or pneumatic actuation.

The design of both the electric and the pneumatic dampers incorporate redundant closure modes for an extra level of safety. Closure of either damper model may be triggered by the fire monitoring/suppression system, or if the fire system fails, the dampers themselves will sense the excess heat from a fire and close automatically. The electrically actuated damper senses the excess heat by using an Electrical Thermal Release (ETR), and the pneumatically actuated damper utilizes a fusible link for the same purpose. All 700-A60R Round Dampers are manufactured using high-grade stainless steel and the finest marine grade components.

Delta “T” Systems’ 700-A60R line of dampers have passed a strict battery of tests in order to earn their A-60 rating, in accordance with the National Fire Protection Association (NFPA) Resolution A.754(18). Approved for use with both BELIMO and ACTIONAIR actuators.
