Vessel Re-Engineering Program

Pentair's NexSys Vessel Re-Engineering Program allows us to adapt your existing filter vessel to utilize our high performance element technologies. Each system is designed to address the specific operational and mechanical constraints of the facility.

We re-configure the vessel to maximize solids loading ability, while simultaneously reducing the number of elements an operator would have to change. A typical NexSys upgrade uses one quarter the number of elements, while simultaneously increasing the on-line life 4-7 times while providing similar fluid quality.

Some examples where upgrades have been done include:
  • String-Wound Cartridge Upgrade: Selexol System
  • Cartridge Upgrade: Rich MDEA System
  • Sour Water Filter Upgrade
  • Ethylene Feed Filter Upgrade
  • Stacked Disk Filter Upgrade: Silicones
  • Natural Gas Processing: Filter / Separator Upgrade
Conventional filter systems can prove to be laborious during change outs, have high change out frequencies and carry significant disposal volumes and costs. An optimized system achieves maximum utility at minimal investment in manpower, capital and expense. Pentair upgrades allow the use of existing capital in a more productive capacity through increased useful surface area, high efficiency media, effective sealing of elements and minimal operator effort.
