Until now, the necessary earthing of hazardous filling goods in ex-zone IBCs took the form of a metal plate, mounted on the outlet valve, that was connected via a screw to the earthing cable and so to the IBC. The threaded flange from Schütz with moulded cable and screw-on mounting plate is made of a synthetic compound with electrically conductive carbon nanotubes (CNT). The new material permits the use of an entirely metal-free module – which also works with a ball valve and camlock adapter.
The flange is welded in the usual way to the outlet nozzle of the IBC’s inner tank and serves as a module onto which the valve can simply be screwed. By doing away with the earthing screw, damage to the outside of the IBC and resultant leaks are ruled out, as are corrosion and its consequences since there is no longer a metal earthing plate to become corroded. The chemical stability of the flange is now identical to that of the IBC’s inner tank.
