Product features

(1) It is composed of two layers of fire curtain surfaces, and the air layer with an interval of about ≥250mm in the middle makes use of the good thermal insulation of air to enhance the fire-proof and thermal insulation performance of the roller shutter, which has the advantages of light weight, good performance and low price.

(2) The fire resistance of the product is 3h, the average speed of electric opening and closing is 2m/min ~ 7.5m/min, and it has two-step closing performance and temperature control release performance. The curtain plate type is double-guide-rail inorganic fire-retardant cloth, and its accessories are transmission device, fire-proof electric door rolling machine, fire-proof control box and independent temperature detector.

(3) The fire shutter does not need water curtain protection, which greatly reduces the investment of water supply system and saves water. It also has good smoke blocking performance; Corrosion resistance, acid and alkali resistance, non-aging, light weight and low price; No deformation in case of fire; Simple structure and convenient installation and use.

serviceable range

It is suitable for fire shutter with fire prevention function in industrial and civil buildings where the temperature rise of the back fire surface of the shutter is judged (average temperature rise ≤140℃ and maximum temperature rise ≤180℃) and the fire resistance limit is ≥ 3.0h.. It is especially suitable for fire partition in places where automatic sprinkler system is not suitable or installed.

Types and performance indicators

The basic structure and material selection of curtain surface should be strictly controlled. The air insulation distance between the two curtain surfaces must be ensured during installation, that is, controlled within the range of ≥ 250 mm.
