SFU – Single Flare Unit – Direct Gas Venting

The SFU – Single Flare Unit is designed for the direct venting of natural gas and LPG. In addition it can operate at up to 2bar and if needed higher pressure supplies can be regulated. The flare burner unit enables any vented gas to be burnt off, where it could cause a problem. The SFU – Single Flare Unit has one burner and one ignition unit. While in contrast the TFU – Twin Flare Unit is also available with two burners and two ignition units.

The unit contains a continuously rated high voltage and switched transformer. This is fed from 110V source via a safety transformer providing a continuous spark for ignition. This is important so that a flame can be maintained as the gas levels decrease.

When the purge is nearing completion the flame will not be maintained and normal gas venting will continue through the stack. The main flare unit is mounted in a vinyl coated wooden and aluminium framed purge box.
