GTFJ-C steel spray superfine fire resisting shutter (hereinafter referred to steel super fire resisting shutter) is one of the important fire prevention facilities in the modern architecture. Its feature is coordination with spray device (spray device water consumption is less, generally it don't number in the fire protection total water), reduce the shutter fire back temperature and improve the refractory limit time. Its refractory limit time ＞4 hours, fire back average temperature ＜60℃．Steel spray superfine fire resisting shutter is controlled by fire protection "central lock" smoke detector and temperature detector to automatic control the fire protection shutter close and spray device start. |
