REWINDER EARTHING SYSTEM (RES)

Rewinder Earthing System for external floating roof tanks is an effective and virtually maintenance free electrical grounding system specifically designed for subduing sustained arcs during lightning storms. The unit is bolted to the highest point of the tank and the tinned copper braided cable is bolted to a point on the floating roof – it extends and retracts as the floating roof travels up and down.

  • Permanent contact between the tank roof and the tank shell
  • The length of grounding cable varies with the position of the floating roof giving the lowest possible impedance/resistance to safely discharge lighting currents
  • The sealed unit is made from stainless steel and can be fitted with the tank in service
  • Weather proof sturdy construction suitable for most environments
  • Can be installed and maintained with the tank in service

FLAME ARRESTER

Detonation Arresters

Withstand and arrest high velocity and pressure flame fronts approaching from either direction in closed or manifolded piping systems.

End-of-Line Parallel Plate Flame Arrester

Provides protection of the tank’s vapor space if an ignition source is introduced outside of the tank. The large wing nut and swing bolt assemblies allow full access to the arrester elements for easy inspection and maintenance. A spare element can be quickly installed to safeguard the tank while the original element is serviced.

Flame Arresters

Prevent exterior flame entry into storage or processing tanks via vent opening.
