Texas Air Conditioning Equipment Co., Ltd. Rui Xincheng smoke damper is usually installed in the pipe mechanical exhaust system, usually it was turned on, when the fire within the flue gas exhaust pipe temperature reaches 280 degrees to close the damper, and in a certain time meet the leak and the amount of smoke in the fire integrity requirements, from smoke fire retardant. Smoke damper main material: carbon steel, galvanized steel, stainless steel. Shandong smoke damper 280 degrees Advantages: corrosion resistance, long life (made of stainless steel type); low air leakage, airtight performance; electric open current consumption is small; Texas Pacific smoke damper actuator drive flexible, feedback, interlock signal accurate. Remote control plate discharges need remote control, remote manual open, DC24V open telecommunications, remote manual reset, feedback on signal or interlocking signal, no warm feeling, with 6m rope. Near the control plate discharges contrast, close to 70 ℃ manually open the damper, DC24V electrical open, close the manual reset, the feedback opening signal or interlocking signal, no temperature-sensitive plate discharges purposes: General Installation exhaust port at the elevator, the corridor, the room with no windows exhaust system, attached to the upper surface of the side wall or ceiling surface. Usually in a normally closed damper melting point, when fire opened for smoke. Operating device mounted near the exhaust port from the high walls of about 200mm ground by rope operating device associated with the exhaust port for remote control, the length of the rope is generally 6m. PY-SFD smoke damper PY-BSFD remote control smoke damper Features: control center DC24V power input, the valve opens quickly. Manually open. Output Enable signal, the fire interlock row machine. Manual reset closed. 280 ℃ temperature sensor operation, close the valve again. PY-BSFD remote control smoke damper may be far from the electric open, manual open, manual close. 280 ℃ damper | Xianyang damper | Rui Xincheng air conditioning provided by the Texas Air Conditioning Equipment Co., Ltd.
