The sash-shutter EDS-SRG-EP is a device suited to the closing and opening of the silos mouth in the spark detector systems.
To get the maximum safety of the system and to avoid that a possible spark can penetrate inside the silos of collection and therefore to provoke very heavy damages, is useful to install at the end of the pipeline and before the linking to the mouth of the silos, this shutter.
The driving of the shutter is enabled by a command sent from the spark detectors or from their control unit.
The shutter is endowed with 2 pneumatic cylinders drived by an electrovalve. When the electrovalve is powered, the shutter opens, when the shutter is not powered it close.
