ATEX approved and compatible with all UK gantry systems, Alpeco’s Tanker Truck Overfill Prevention equipment is failsafe in operation and ensures optimum protection against dangerous overfills. The bottom socket incorporates an interlock facility and pressure switch which ensures that the tanker is correctly vented for bottom loading, whilst a brake interlock switch prevents the tanker from being moved whilst the rack monitor is still connected. A top socket with brake interlock provides overfill security for top loading.
