Product Overview
This EH oil acid removal regeneration cartridge is a professional adsorption filter specially designed for power plant phosphate ester fire-resistant hydraulic oil systems. Different from conventional glass fiber particle filters that only trap solid contaminants, this regeneration filter focuses on chemical purification. It effectively removes acidic substances, dissolved moisture, metal ions and oxidation by-products generated by EH oil hydrolysis and aging, stabilizes oil acid value and resistivity, and thoroughly solves common system failures caused by oil deterioration.
Widely compatible with mainstream EH oil regeneration devices, including Nugent, Pall and domestic power plant regeneration systems, it is a core consumable for long-term stable operation of turbine electro-hydraulic control systems.
Core Working Principle
EH phosphate ester fire-resistant oil is prone to hydrolysis and oxidation under high temperature and high-pressure operating conditions, producing acidic substances and conductive metal ions, which will corrode servo valves, block fine pipelines and reduce system control accuracy. Our acid removal filter adopts three professional adsorption and purification technologies to restore oil performance:
-
Activated Alumina Media: Dual functions of acid removal and dehydration, stable performance, no secondary pollution, the most widely used universal type for power plants
-
Fuller’s Earth (Diatomite) Media: Efficient acid reduction, suitable for old power plant regeneration systems, effectively controls rising oil acid value
-
Ion Exchange Resin Media: Strong ion exchange capacity, efficiently removes metal ions, significantly improves oil resistivity, ideal for high-precision EH system purification
Key Product Features
-
Professional EH Oil Customization: Equipped with FKM fluororubber seals as standard, perfectly resistant to phosphate ester corrosion, no swelling or leakage, completely adapted to fire-resistant oil working conditions (NBR seals are not applicable)
-
Integrated Protective Structure: Full stainless steel perforated outer skeleton, protects internal adsorption filler, prevents powder leakage, ensures oil cleanliness and avoids secondary system pollution
-
Stable Purification Performance: Effectively inhibits EH oil degradation, maintains oil acid value and resistivity within the factory standard range, protects precision servo valves and hydraulic components
-
Easy Installation & Replacement: 1:1 original standard size, direct plug-and-play replacement, no modification required, reduces equipment maintenance downtime
-
Long Service Life: High-density filled adsorbent media, large adsorption capacity, longer replacement cycle than ordinary alternative filters, reduces operating costs
Clear Product Classification & Selection Guide
Most EH acid removal filters have identical outer dimensions but different internal media and functions, NOT INTERCHANGEABLE. Please select strictly according to on-site equipment configuration:
-
Activated Alumina Type: Universal model, balances acid removal and dehydration, suitable for most mainstream power plant EH systems (Compatible with 30-150-219)
-
Diatomite Type: Focuses on acid reduction, applicable to traditional old regeneration devices (Compatible with 30-150-207, PTS-59332)
-
Ion Exchange Resin Type: Divided into cation and anion types, used in pairs for high-precision purification, removes metal ions and reduces acid value simultaneously (Compatible with PFC8370R3CH83 / PFC8370R3AH83, ET718-DR-03ZXC0)
Application Scenarios
Specially used for power plant turbine EH fire-resistant oil regeneration systems, applicable to thermal power generation units, petrochemical hydraulic control systems and other scenarios using phosphate ester fire-resistant oil. It is an essential consumable to ensure the safe and stable operation of electro-hydraulic control systems.
