Product Brand: TOMSON
Product name: TOMSON Water mist Special fireproof & Smoke-proof Rolling Shutters
Product features: Fire-proof; Insulation; Smoke-proof
Project Cases: METRO supermarket

Product Material: Side rails and end plates are available in galvanized steel and stainless steel.
The end panel has two forms: double curtain split type and double curtain combined type.
TOMSON Water mist special fireproof and smoke-proof rolling shutter products use a tangential vortex nozzle to atomize water to droplets of about 0.1mm and spray it on the rolling curtain surface to perform forced cooling on the rolling curtain surface. Compared with the addition of independent closed automatic water spraying systems on both sides of the high-quality fire-resistant roller shutter, the water consumption can be saved.
TOMSON water mist special fireproof smoke-proof rolling shutters are suitable for industrial and civil use with the temperature rise of the back surface of the rolling shutter as the judgment condition (average temperature rise≦140 ℃, maximum temperature rise≦180 ℃), fire resistance limit ≧3. In the building, there is no automatic spraying area separation.
