ICB Ion-Exchange Filter

Often imitated. Never duplicated. Patented ICB ion-exchange filter.

Meet ICB RO

for Rust & Oxidation Turbine Oil

ICB RO removes varnish precursors and dissolved breakdown products continuously, breaking the accumulation cycle and eliminating the root cause of varnish formation.

Meet ICB FRF

for Phosphate Ester Fluid

ICB FRF is designed to address phosphate ester chemistry, removing acids, phenols and varnish while simultaneously improving resistivity, preventing EHC failures.

Meet ICB JET

for Aeroderivative Turbine Oil

ICB JET removes acids, oil coking precursors, and dissolved by-products continuously, breaking the accumulation cycle and eliminating the root cause of deposit formation.

Meet ICB AW

for Anti-Wear Hydraulic Oil

ICB AW selectively removes varnish and varnish feedstocks continuously, breaking the accumulation cycle and preventing varnish problems altogether.

Stop Servo Valve Sticking in its Tracks

The ICB™ ion-exchange filter is manufactured with one goal in mind, to remove the dissolved molecules that accumulate and cause mechanical problems in hydraulic systems and lube oil applications. These filters are engineered workhorses based on patented ion exchange technology, combining best-in-class chemistry and materials with precision robotic welding to provide the most robust filter available.

ICB is chemically engineered to remove a wide range of contamination, including acid, varnish, and metals. In EHC systems, ICB filters remove the contamination responsible for servo valve sticking, restoring fluid resistivity. ICB filters offer a step-change in performance, protecting system reliability and production with so many benefits beyond acid removal.

History of the ICB Ion-Exchange Filter

In 1992 EPT Clean Oil founder Peter Dufresne Sr., discovered the step-change benefit of employing ion-exchange filtration technology within turbine lube oil systems.

Peter’s pioneering research in this field created the market for ion-exchange purification and our ICB branded filters. With the ability to adsorb soluble varnish, ICB filters remove harmful oxidation materials ensuring that they do not accumulate in the lubricant, mitigating the risk of varnish formation.

ICB Ion-Exchange Filter. Unmatched Performance.

ICB Filters offer unmatched performance in the removal of acids, dissolved oxidation material and other molecules responsible for:

  • slow or sticking servo valves
  • bearing deposits
  • bearing failures
  • other mechanical issues that would otherwise result in production losses

ICB filters remove the underlying cause of varnish and remove existing deposits by restoring fluid solubility, shifting chemical equilibrium back towards the original fluid condition:

  • 100% effective under standard turbine operating conditions when the varnish is dissolved in the oil
  • Restores fluid’s electrical properties protecting mechanical components
  • Create stability within lubricant and fluid systems, mitigating premature deterioration
  • Complete stainless-steel construction featuring robotic, spiral welding, which provides maximum filter integrity
  • Filter pressure tested to 150 psid
  • Compatible with EHC fluids and turbine lubricants

Don’t wait for your acid levels to rise. Protect and manage lubricant life and system reliability with ICB Ion-exchange Filters today.

ICB Filter by Lubricant Category

While initially developed for phosphate ester lubricants back in 1992, EPT Clean Oil has expanded the capabilities of ICB filters to accommodate a wide range of lubricants and additive types.
