Reliable Oil Treatment with the OFWA System

Introduction

At ILF Solutions, we supply advanced oil treatment systems that protect industrial equipment, power generation facilities, and marine engines from water contamination and harmful particles. The OFWA Oil Treatment System is a safe, fully automatic solution designed to filter oil and separate water with flow capacities from 5 l/min to 16 l/min.

Engineered for industrial, shipping, and power station environments, the OFWA system ensures residual water content of less than 70 ppm, making it far more efficient than conventional oil treatment technologies.

Key Features & Benefits

Filtration & Water Separation in One System
Delivers clean, dry oil by removing both solid contaminants and free water.

Fully Automatic Operation
Automatic water discharge, pressure monitoring, and alarms ensure safe, hands-free operation.

Compact, Space-Saving Design
Ideal for engine rooms, control areas, and compact power generation facilities.

High Efficiency & Reliability
Reduces free water content to <70 ppm, protecting against corrosion and extending oil service life.

Low Maintenance & Long Service Intervals
Built for reduced downtime and lower operating costs.

Robust & Proven Technology
Sturdy construction with steel tank, sand-blasted and coated finish, and IP54 protection class for safe global use.

How the OFWA Works

Pumping
A geared pump delivers lubricating oil to the treatment stage.

Filtration & Separation
Oil passes through a treatment module that removes solids and coalesces water droplets.

Automatic Water Discharge
A water probe detects separated water and discharges it automatically.

Differential Pressure Monitoring
The system monitors filter soiling. At 1.3 bar, a pre-alarm is triggered. At 1.5 bar, a main alarm signals replacement.

Bypass System for Safety
If the filter is not replaced, a relief valve opens to keep oil flowing. The oil bypasses the treatment stage and relies on engine filters, ensuring continued operation.

Applications

Industrial Facilities – Protects turbines, pumps, and machinery from water and particle contamination.
Power Stations – Ensures lubricating oil for generators remains clean and safe for long-term operation.
Shipping – Used onboard vessels to maintain reliable lubricating oil quality in critical marine engines.
