Product features
Product is made of tangential vortex type sprinkler, spray the water to the 0.1 mm or so of water droplets, spray to the shutter shade, the shutter shade face forced cooling, with ordinary steel fire shutter shade on both sides of the compared with independent closed sprinkler system, can save the water.
Using range
Applicable to fire shutter back surface temperature rise as the decision condition (average ≦ temperature 140 ℃, the highest temperature rise ≦ 180 ℃), fireproof limit ≧ 3. Oh) of industrial and civil architecture has no automatic spray fire area of space.
