Special Grade Fire Roller Shutter

Product features

(1) composed of two layers of fireproof curtain surface, at an interval of about equal to or greater than 250mm air layer, using air, good heat insulation, enhance shutter fireproof heat insulation performance, with light weight, good performance, low price advantage.
(2) refractory products performance for 3h, electric opening and closing an average speed of 2m / min to 7.5m/min with two step closure properties and temperature control release properties, curtain plate type dual rail inorganic flame retardant fabric and accessories transmission device, fire electric rolling door machine, fire control box, freestanding feeling temperature detector etc.;
(3) the fire shutter without water curtain protection, greatly reduce the investment of water supply system, water saving. It also has good characteristics of good smoke, corrosion resistance, acid and alkali, not aging, light weight, low price, no deformation of the case of fire, the structure is simple, easy to install and so on.

Application in rolling back fire surface temperature rise is to determine the conditions (average temperature rise is less than or equal to 140 DEG C, the highest temperature rise is less than or equal to 180 DEG C), 3.0h of refractory limit is equal to or larger than the industrial and civil buildings, with fire prevention function of the fireproof rolling shutter. Especially suitable for fire partition partition in the place where it is not suitable for automatic sprinkler system.
