HYLTRIS Hydraulic Fluid Filtration

Engineering Reference · Industrial & Process

Platform: FLUREXIS™

Technology: HYLTRIS™

Engineering Relationships

  • HYLTRIS™ addresses solid particulate contamination and wear debris in industrial hydraulic systems.
  • Pressure-line, return-line and offline locations impose different pressure, flow and contamination duties.
  • Fluid viscosity and startup temperature affect differential pressure independently of contamination loading.
  • Element sealing, bypass control and housing compatibility are necessary to preserve the intended filtration path.
  • Sustained system cleanliness depends on removal performance, element placement, contamination generation and ingression together.
  • HYLTRIS™ is an Industrial & Process family and does not inherit NANOFORCE™ branding or claims.
  • HYLTRIS™ maps to TC-HYD-01 within FLUREXIS™.

Components

  • Hydraulic filtration element
  • Pressure, return or offline housing interface
  • Element seals and bypass arrangement
  • Differential-pressure indicator or monitoring point
  • Offline recirculation loop where used

Problems

  • Solid contamination
  • Wear debris
  • Persistent cleanliness instability
  • Excessive restriction
  • Short element life
  • Bypass or sealing defects

Failure Modes

  • Element loading beyond qualified duty
  • Cold-start restriction
  • Bypass opening or leakage
  • Seal or seating failure
  • Incorrect filter location or sizing
  • Ingression rate exceeds cleanup capability

Symptoms

  • Particle cleanliness does not recover
  • Differential pressure rises unexpectedly
  • Valve, pump or actuator contamination repeats
  • Filter intervals shorten
  • Restriction is highest at cold startup
  • Bypass or seal evidence appears during inspection

Root Causes

  • High external ingression
  • Abnormal wear generation
  • Viscosity outside the selection basis
  • Undersized element or housing
  • Incorrect bypass or seal configuration
  • Offline turnover insufficient for contamination generation

Diagnostic Methods

  • Confirm fluid type, viscosity and temperature.
  • Confirm pressure-line, return-line or offline installation location.
  • Trend differential pressure with flow and temperature.
  • Characterize particle cleanliness and contamination source.
  • Inspect element seating, seals and bypass configuration.
  • Compare actual flow and pressure duty with the selection basis.

Corrective Actions

  • Correct contamination ingress or abnormal wear source.
  • Requalify element and housing sizing for actual viscosity, flow and pressure.
  • Correct bypass, seal or seating defects.
  • Add or resize offline conditioning when system cleanup demand requires it.
  • Verify improvement through representative particle-count monitoring.

Maintenance Procedures

  • Trend differential pressure under comparable temperature and flow.
  • Inspect seals, bypass components and element seating during changeout.
  • Review cleanliness trends after maintenance, fluid additions or component failures.
  • Investigate repeated short element life before specifying finer media.
  • Maintain representative sampling points and clean sampling practice.

Operating Conditions

  • Fluid chemistry
  • Viscosity and temperature
  • Pressure and pressure cycling
  • Flow and flow transients
  • Particle loading and ingression
  • Cleanliness objective
  • Installation location
  • Housing and bypass arrangement
