Safe Hot Refueling


Proven and Reliable Design


Automatic Shut Off

Features & Benefits

Features & Benefits

The G457 allows an operator to safely refuel a helicopter while its rotors are still running. Its innovative proximity lever eliminates the risk of fuel being sucked into the air intake, in turn removing the dangerous human error element encountered when hot refueling.

The nozzle will automatically shut off when a helicopter’s tank is full, minimising spillages. It also features a manual override mechanism to allow an operator to fill a tank to its absolute maximum. This is especially important in situations where a helicopter needs to remain airborne for as long as possible.

 

Other features include:

  • Anti-froth device
  • Fuel-resistant buna-N splashguard
  • 100 mesh inlet strainer standard
  • Black anodised finish for all-weather protection
  • Swivel integrated into inlet

Applications

Applications

Hot refueling can be dangerous if not managed correctly. Yet it is also critical for helping helicopters get airborne in time-sensitive situations, such as combat environments or emergency response.

While originally designed for the defence sector, this product can be used whenever there is a need for rapid hot refueling without any of the associated risks. Alongside a major NATO partner, customers include the US Forest Service and Federal Aviation Administration.
