1. Core fire and smoke isolation capability: When the smoke temperature reaches the set value (such as 70 ℃, 280 ℃), it can quickly and automatically shut down, effectively blocking the spread of flames and high-temperature smoke through the air duct, and buying time for personnel evacuation and fire extinguishing. It is a key protective component of the building fire protection system.
2. Sensitive and reliable response: Equipped with high-precision temperature sensors or linked fire control systems, the closing action is triggered quickly, and the sealing performance is good after closing, ensuring stable partition effect and reducing the risk of fire spread.
3. Strong adaptability: Different specifications (size, temperature level) can be designed according to different scene requirements (such as ventilation system, smoke exhaust system), compatible with various types of air duct installations, and meet the fire safety requirements of various buildings such as office buildings, shopping malls, industrial plants, underground garages, etc.
4. It has both ventilation and safety functions: it can be kept on normally without affecting the normal air circulation of the air conditioning and ventilation system; Automatically switch to fire prevention mode during a fire, achieving the integration of "daily ventilation+emergency fire prevention" without occupying additional space.
