Features & Benefits

Features & Benefits

The PosiLock 105 closed loop fuel system comprises of a lightweight fueling nozzle and filler neck. The nozzle is attached to a fuelling station while the filler neck is mounted onto the tank of a vehicle.

Both the nozzle and filler neck are equipped with dry-break disconnect couplings. This eliminates fuel spillage during operation, helping organisations to minimise losses when processing a high number of vehicles throughout the day. These couplings will also help save on disposal costs once fuel has been collected in separators and eliminate the risk of theft. Nozzles will not dispense without an active connection and tanks are inaccessible once a filler neck has been fitted.

The PosiLock 105’s nozzle is capable of dispensing fuel up to 185 litres/min (50 US gallons/min), allowing a high throughput of vehicles during busy periods. The system is also fitted with a pressure gauge that triggers automatic shut off, so operators are free to attend to other tasks while a tank is being filled. These features significantly speed up the time it takes to prepare a fleet for the road.

Arguably the biggest benefit of the PosiLock 105 is its in-built fuel level, which guarantees every tank is filled to 95% capacity. This avoids premature underfueling, which can cause vehicles to stop mid traffic and add delays to a schedule. Better still the system’s design limits operator issues, so common human errors associated with fueling is virtually eliminated.
