Weiss Fuel Conditioning System

Fuel Conditioning Test System

Weiss Fuel Conditioning Test Systems are used to carry out ORVR refuelling in vehicles for compliance with legal regulations and to test vehicle tanks. In addition to the supply tank, the main components include various gasoline nozzles, active and passive vapour recovery and a pre-pay function.

The test system has four functions - circulating and tempering fuel, refuelling (the vehicle), pumping out fuel (from the vehicle) and an emptying system. The Fuel Conditioning Test System enables fuelling with all common fuels, temperature conditioning of the test fuels and fuelling with defined rates and quantities.
