engelopes GAS WASHERS AN EFFICIENT AND MUCH MORE ECONOMIC WAY OF ELIMINATING AIR POLUITION!
MAIN APPLICATIONS
It is the only Fire Damper in the market especially designed
for application in exhaust pipes of air derived from food cooking, always saturated
with fat and/or soot and usually flammable, being developed on the basis of our long
experience in the manufacturing of air de-polluting equipment for restaurant
kitchens and others alike..
TECHNICAL STANDARDS
The project development complies with all pertinent technical
standards and mainly the new ABNT Standard no. 14.518 specifically covering Safety and
Specifications for Mechanical Exhaustion Systems for Kitchens Exhaust Hoods.
DESIGN
The design of our "DCFG" type Fire Break Damper primarily considered
the NON-EXISTENCE of any device or part in its interior which might impair air flow or provoke
the accumulation of grease and/or soot. Also, in order to facilitate maintenance services, ALL
activating devices are located in the external part of DCFG. To facilitate internal cleaning,
the DCFG is fully removable, being equipped with flanges for coupling to ducts, which may have
an asbestos seal gasket, turning the group formed by DCFG and the PIPES fully sealed to flame
propagation.
CONSTRUCTION
The whole DCFG is fully built in #14 black carbon steel plates,
complying with current Standards and Legislation and resulting in a totally fire resistant
device. Its Sealing Plate, once closed, is housed in a peripheral tappet fully sealing the
passage of the exhausted air from the inlet to the outlet. In order to be high temperature
resistant, the Plate is built in the shape of a steel plate sandwich with an isolating
mineral fiber filling, preventing the flame propagation beyond their point of origin.
OPERATION
The DCFG activation can be done in two distinctive and more usual ways:
ELECTRICALLY - by means of a solenoid which receives a signal issued by a thermostat
installed in the interior of the pipe, or MECHANICALLY - which uses an electric fuse element.
Both ways RAPIDLY unlock the internal Seal Plate existing in DCFG, which propelled by a highly
resistant spring, reaches a closing position whereby a special safety lock maintains it fixed.
