HTF series of high-temperature fire exhaust fan Overview: HTF series fire temperature exhaust fan with excellent performance, high temperature performance, high efficiency, covering less than the centrifugal fan, convenient installation. HTF series fire temperature exhaust fan of "national fixed fire extinguishing systems and fire-resistant component quality inspection center" test qualified, the performance of the leading domestic level. High temperature performance: Fan tested in accordance with GBJ45-82 Fire Code standards, establish higher standards of corporate internal controls to ensure that the system can operate continuously at 300 ℃ high temperature for 60 minutes or more two-speed exhaust fan, 100 ℃ temperature conditions for 20 hours / time is not damaged, is widely used in high-level civil oven, underground garages, tunnels and other occasions. Fire exhaust fan set Location: Distance tunnel fire exhaust fan should not be too close to the side wall exhaust fan, so as not to affect the ventilation exhaust fan fire tunnel wall arranged for a minimum distance from 20 cm, rescue "sentinel" settings. Disaster tunnel is divided into different regions of axial exhaust fan, make full use of deviated and both ends of the tunnel exhaust fan fire rescue station designated as the wind and smoke into the new channel, cross ventilation openings must maintain positive pressure state prevent flue gas flow channel. ventilation system to air, flue gas into a cross-channel and suppress tunnel accident did not occur to meet a cross from the secure tunnel through the channel tunnel to the accident evacuation direction facing the new air into the tunnel cross passages and safety while ensuring the required waiting area with fresh air. According to different regions within the tunnel accident Disaster different ventilation mode. When the "sentinel" Disaster ventilation scheme implemented when the train rescue point in the "sentinel" range for all contacts Cross channel settings can be inverted to obtain a fresh wind from the fan inside the secure tunnel.
