Defueling Assemblies

ANGI can provide standard or custom defueling assemblies. The defueling assemblies are used for:

  • Defueling a vehicle before servicing - These assemblies typically connect near the vehicle cylinders and safely remove CNG from a vehicle tank prior to servicing the CNG vehicle.  The customer will specify where to direct the CNG that is removed from the vehicle tank.  These locations may include:  suction of the compressor, pipeline, other low pressure natural gas system or may be atmospherically vented.
  • Defueling a storage trailer - At sites that do not have natural gas, the gas can be delivered over the road, in a tube trailer.  ANGI provides defueling panels that safely move gas from the tube trailer to where it is used, such as:  a daughter CNG station, a distribution pipeline or industrial natural gas user.  

Defueling panels can also include pressure monitoring and flow metering.
