GUMT
Control and discharge system for electrostatic charges suitable for road tankers, rail tankers and any movable tanker for dangerous items, ready for one/two double circuit clamps PTA ISEO-2. System is complete with arrest/consensus optical warning and changeover contact free from output voltage.
The need to transfer from one place to another dangerous flammable fuels and liquids as gasoline and diesel highlighted the serious risk due to uncontrolled discharge of static charges cumulated on movable tanker-units during transfers following the well known natural phenomena when connected to loading / downloading tools (fixed). Following the natural tendency to the equilibrium of electrical potential a loading harm of a fuel depot, being connected to general earth circuit, will act as a discharge preferential path of all static charges cumulated on a next road tanker to load for instance gasoline.
Very probably the same road tanker should have inside the residual vapours of previous load. Therefore the discharges of static following the insert of loading harm in the tanker will generate a spark with an energy enough to ignite the mixer gasoline – air present inside. Therefore to cause an explosion with all terrible consequences that can effect on humans and apparatus. The same condition can happen on rail tankers as well as movable barrels in use in paint manufacturing process, for instance between the harm of a mixer and the barrel of paint. The solution of the problem is to control the discharge of static charges driving it thought a dedicated and safe path. Safe because Explosion proof.
