Marine Dampers
Application — So often overlooked in the majority
of marine applications, this difcult to nd, yet vital
safety component is now designed and produced
for the Yacht & Shipbuilding Industries exclusively
by Delta “T” Systems. The effectiveness of any
installed re system can be greatly enhanced if the
ventilation openings to the protected compartment
are closed at or before the discharge of the extin-
guishing agent. In the event of a re system dis-
charge, the Marine Smoke/Fire Damper provides
for nearly instantaneous closure of the ventilation
openings, thus preventing dilution of the extin-
guishing agent as well as preventing additional
oxygen to enter the space to fuel and spread a
re. The Delta “T” Systems Marine Smoke/Fire
Damper is an integral part of a properly designed
ventilation and re protection system aboard any
vessel. Our Circular Dampers are designed to
close couple directly to either end of Delta “T”
Systems Marine Axial Fans to provide the safest,
most compact, high volume ventilation component
assembly available. The short casing design allows
the damper blade to project into the open section
of the plenum to minimize overall length. Dampers
may also be installed independently within an
air shaft or plenum if no fan is installed. Using
silicone blade seals, these units are provided with
a simple mounting ange for attachment. These
dampers may be congured in a wide variety of
sizes. Dampers may be automatically closed via
a pneumatically controlled actuator. Actuators
are suitable for use with CO
2
, Halon, FM-200 and
other pressurized re suppression systems and
are U.S. Coast Guard (162.038/7/0), American
Bureau of Shipping, UL (EX-2968) and Factory
Mutual type approved. Just 70 PSI is required
to provide instantaneous spring loaded closure
of the air duct. Dampers may also be manually
actuated and reset from outside of the damper
casing. As an option, all dampers may be tted
with electric “fail-safe” type actuators. These are
available in 24 volts DC, 115 volts or 230 volts AC.
Electric dampers will close automatically upon loss
of electrical current supply.
