Damper manufacturer, central air conditioning equipment manufacturer (certified), fire dampers

Exhaust valves, with the three, each unit different names, some based on its operating temperature is called the exhaust valves, and some based on its use of nature called damper, but just an ordinary damper device side fuse metal exchange 280 degrees blown into that kind of .3 automatic smoke damper (Metro Engineering) fire subway ventilation and air conditioning systems, exhaust valves have automatic fire alarm equipment and gas extinguishing system linkage control functions. Each automatic smoke dampers have two independent electric control signal, respectively, by EMCS, gas consumption system to monitor, control signals are DC24V ± 10% signal. Each automatic smoke dampers have six independent feedback signal (three open place, three off place) feedback signals are normally open dry contact signal. Professionals to explain the role of smoke fire retardant fire damper as an engineering construction and installation of fire dampers essential fire-fighting facilities, which can effectively prevent the spread of fire, to promote a safe environment to play an important role off. In order to make better use of this damper we must first understand before using his function, so as to better facilitate our use. Damper in use played a role in the fire damper smoke fire retardant manufacturers, in the air supply system, air blower sent through the main pipe must be allocated to the branch pipe; in the exhaust system, the flue gas from the manifold to the main pipe After entering the exhaust fan discharge. When a fire broke out in the building, ventilation, air-conditioning systems in order to prevent the fire from spreading through the air supply system, gas supply system when the temperature reaches 70 ℃, the damper mechanism fuse action, the valve will quickly close the valve, cut flue duct and the fire spread along the path. Similarly damper prices in the exhaust system, the case of fire, smoke exhaust valve opens, make smoke, in order to cut off the flow of high temperature gas in the exhaust pipe to prevent the fire from spreading to another fire district in Texas damper manufacturers, When the exhaust flue gas temperature reaches 280 ℃ damper, smoke damper on the exhaust port fuse action, the valve must be automatically shut down to prevent smoke. Thus, fire dampers, exhaust valves so that the general rule pass, which is broken off smoke fire retardant effect.
