We would like to introduce the principles and overview of the "AIS-P" that we handle. The explosion suppression system (AIS-P) detects the onset of an explosion pressure rise and rapidly disperses a suppression agent to extinguish the flames and inert the surrounding space. As a result, the rising pressure is interrupted (pressure suppression). This means that even though an explosion may have been about to occur in the process, it can be brought to an end without leaving any traces. However, the restoration of the activated suppression system will be necessary.

The "ATEX Float Valve" is a valve developed through continuous improvements as a passive shut-off valve that blocks the propagation of deflagration in ducts. During an explosion, the float valve, which is latched in the open position by the wind speed of the explosion, moves axially and is fixed in the closed position, thereby stopping the propagation. This fundamentally improves the turbulence, pressure loss, and malfunction caused by the floating of the float valve, which were issues in the past. 【Features】 ■ No gaskets used ■ Pressure-resistant passive shut-off valve ■ Float valve has opening and closing latches ■ Pressure loss and turbulence of the powder flow passing through the float valve during operation are minimal *For more details, please refer to the catalog or feel free to contact us.
