Oil and Lubricant Filtration Using Press Filter and Thermo-Vacuum Technology

"

AFE Services delivers a fully integrated solution for the dialysis and purification of hydraulic, lubricants, thermal, and process oils, using the most advanced technologies worldwide.

Integrated Solution

AFE Services offers a comprehensive service using:

POWER 30 filter press units: high-efficiency micron cellulose filter media (1–3 microns) combined with coalescing cotton fiber elements (5 microns).
PALL HLP 6 oil dialysis and purification system: developed by PALL CORPORATION, the global leader in oil purification technologies.

The PALL HLP 6 represents the most advanced thermo-vacuum oil dialysis technology available worldwide, combining dialysis efficiency with automation, reliability, and ease of operation.

Process and Operation

Phase 1: PD POWER 30 dialyzers reduce contamination levels, even in severely contaminated oils.
Phase 2: Thermo-vacuum processing with PALL HLP 6 removes residual dissolved, free, or emulsified moisture.
Separation Tower: Equipped with precision rings to maximize oil-air contact, ensuring efficient water removal.
Automation: Outlet pump adjusts flow rates to maintain optimal oil levels; fully PLC-controlled system allows continuous operation without manual supervision.
Real-time verification: Online laser cleanliness technology ensures compliance with ISO 4406 codes.

Why It Matters

Water contamination in hydraulic systems is a primary cause of failures and premature maintenance in assets such as:

Power generation turbines.
Paper production machinery.
Injection molding systems.

Typical issues caused by water contamination include:

Accelerated system corrosion (especially bearings).
Increased oil oxidation and acid formation.
Sluggish response from hydraulic and control systems.

ISO Cleanliness Code 4406:1999

AFE Services ensures that the treated oils comply with ISO 4406:1999 cleanliness codes, guaranteeing that solid particles and moisture remain within acceptable limits for the safe operation of hydraulic and lubrication systems.
