Incorporating a “dry break” fueling nozzle, the Wiggins diesel fast fuel system allows service personnel to fuel vehicles with both feet on the ground. Delivering fuel at rates up to 570 litres per minute, the Wiggins advanced vehicle fuel system provides cost savings by fueling at a rate six times faster than with the traditional “splash fueling” method, while greatly reducing the risk of injury due to slips and falls by service personnel. The bottom fill concept also reduces foaming, which previously resulted in partial fuel loads requiring vehicles to return to the fueling point multiple times during each work shift.
Wiggins fluid coupling systems for crankcase oil change, transmission fluid service, hydraulic oil maintenance and cooling fluid fill produce similar productivity increases through better fluid control. In addition, the automatic shut-off, no spill, closed loop fueling system reduces costs associated with cleaning fluid spills. More than 90% of all large mine operations use Wiggins Service Systems. Wiggins is the world-wide leader in fast diesel fueling technology.
How It Works
The Wiggins “fast fuel” System is based on the simple concept of using a sealed vehicle tank to allow a small amount of back pressure to build up and automatically shut off the ZZ9A1 nozzle. A receiver is mounted on the tank, located near the bottom. Bottom filling helps eliminate foaming, which can occur during top fueling “splash fill”.
The Wiggins ZZ9A1 nozzle is attached to the receiver, the handle is turned to the “ON” position, and fuel begins to fill the fuel tank at a rate up to 570 Litres per minute. As fuel enters the tank, it forces the air inside the tank to exit through the Wiggins vent. When the fuel level nears the top of the tank, the “hollow floating balls” force the third “solid ball” to seal against the vent “stem”, sealing the tank and stopping the air flow out of the tank. As fuel continues to flow, pressure inside the tank builds until it reaches 8 to 10 PSIG. At 8 to 10 PSIG, the nozzle automatically shuts off. The nozzle shut off is gradual, preventing a hammer effect, which could damage the fuel line. The nozzle can then be removed, and is ready to fuel the next Advantages of the vehicle!
