Electrostatic capture of oxidation byproducts and varnish precursors that pass through conventional mechanical filtration.

ICB Ion Charge Bonding Filter Elements

Overview

ICB elements use ion-exchange media to attract and retain polar degradation products that pass through conventional mechanical filtration. These charged species—including organic acids, aldehydes, and ketones—are precursors to varnish deposits and contribute to servo valve stiction, bearing wear, and reduced fluid life.

Operating Principle

Proprietary ion-exchange resin creates strong electrostatic attraction for polar contaminants below 1 µm
Captures soft, dissolved oxidation byproducts that depth media cannot mechanically filter
Reduces acid number (AN) by adsorbing carboxylic acids before they attack system components
Improves fluid resistivity in phosphate ester systems (target >8 GΩ·cm for EHC applications)

Performance Characteristics

Acid removal capacity typically 2–4× higher than conventional Fuller's earth or activated alumina
Effective on mineral oils, PAO synthetics, and phosphate ester fire-resistant fluids
Operating temperature range: -20°C to +90°C (mineral/PAO) or +80°C max (phosphate ester)
Recommended flow rates: 2–10 gpm per element depending on contamination severity

Applications

Turbine lube and EHC systems experiencing varnish-related valve stiction
Hydraulic systems with elevated acid numbers (AN > 0.2 mg KOH/g)
Compressor oils showing early oxidation (RPVOT < 75% of new oil)
Kidney loop polishing circuits for continuous fluid conditioning

Installation Options

Inline: Install in return line for continuous treatment during operation
Offline kidney loop: Dedicated recirculation for accelerated fluid recovery
Portable filtration cart: Periodic treatment of multiple systems
