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.
