ERS Bundle Rehab

The ERS Bundle Rehab includes:

  • Blasting and Salt-X to remove entrained chlorides.
  • Plugging the tubes and rebuild the surface over the plugs with ERS-5400 Channel Guard HP Paste Grade.
  • After grinding flush and removing the plugs a final coat of ERS-5400 Channel Guard Liquid Grade is applied to provide a monolithic system with an improved, smooth flow surface for every single tube entrance.
  • This system provides a long-term extension to the bundle service life.
