Core Technology & Operation
Centrifugal Disc Separation:
-
Utilizes a self-cleaning disc stack centrifuge that applies high centrifugal force to efficiently separate solid particles, water and impurities from oils.
-
The “91” designation indicates a model optimized for lighter fuels such as marine diesel and gas oil, as well as other oil types.
Pressure-Discharge System:
-
Both clean oil and separated heavy phases are discharged under pressure, commonly using double centripetal pumps, enabling easy integration back into system circuits without requiring additional booster pumps.
-
The double liquid discharge design enhances continuous operation and reduces maintenance.
Robust Mechanical Design:
-
Built with industrial-grade components and a vertical flange-mounted motor, providing stable, reliable drive power and a compact footprint.
-
Hinged hood and solids catcher allow straightforward access for maintenance and cleaning, improving serviceability.
Typical Marine Applications
✔ Fuel Oil Purification:
Improves quality of marine fuels by removing water and debris prior to injection into main and auxiliary engines — enhancing combustion efficiency and reducing injector wear.
✔ Lube Oil Conditioning:
Ensures clean lubricating oil for crankcases, gearboxes, compressors and turbine systems aboard vessels.
✔ Continuous Engine Room Use:
Designed for 24/7 operation in ship engine rooms, offshore support vessels, tankers and other marine installations where reliable oil quality is critical.
Typical Industrial Uses
✔ Power Generation:
Purifies fuel and lubricating oils for diesel or gas turbine generators to ensure stable and efficient performance with reduced unplanned downtime.
✔ Heavy & Process Machinery:
Keeps oils free from water and solids in compressors, hydraulic systems, gears and industrial engines.
✔ Oil Storage & Conditioning:
Pre-treats stored fuel and lube oils, ensuring quality before transfer or circulation in large industrial systems.
Key Benefits
✅ High Separation Efficiency: Removes water and solid contaminants to maintain oil quality and protect equipment integrity.
✅ Reduced Maintenance Costs: Cleaner oil extends component life and lowers frequency of oil changes.
✅ Continuous Operation: Designed for reliable, long-term service in harsh marine and industrial environments.
✅ Easy Serviceability: Hinged access and practical design simplify routine servicing and inspections.
