Core Separation Technology

High-Efficiency Centrifugal Separation

• The unit uses centrifugal force generated by a rapidly spinning self-cleaning bowl: heavier contaminants (water, solids) are thrown outward while lighter clean oil remains near the center.

• Automatic self-cleaning bowl minimizes manual intervention and helps maintain continuous operation with reduced maintenance.

• Pressure-discharged output: Clean oil and separated waste can be discharged at adjustable pressures (typically ~1–2 bar), simplifying reintegration into fuel or lubrication systems.

Design & Construction

• Robust design: Built to withstand heavy marine conditions and harsh industrial environments, including high temperatures and vibration.

• Stainless steel and industrial components: Ensure long service life and corrosion resistance in oil-handling settings.

• Typical high bowl speed: Up to ~11,500 rpm to enhance separation efficiency.

Typical Marine Applications

✔ Fuel Oil Purification: Removes water, sludge and solid contaminants from marine fuels before combustion, leading to better engine performance, fewer injector problems and improved fuel economy.
✔ Lube Oil Conditioning: Improves the quality of lubricating oils for main engines, auxiliary engines, compressors and turbines, enhancing reliability and reducing wear.
✔ Engine Room Systems: Continuous operation supports shipboard systems in merchant vessels, offshore support vessels and other marine installations.

Typical Industrial Uses

✔ Power Generation: Purifies fuel oils and lubricants for diesel generators and industrial turbines, improving operational stability and reducing unscheduled downtime.
✔ Heavy Machinery & Compressors: Ensures clean oil for compressors, hydraulic systems and industrial gear drives. 
✔ Oil Storage & Handling: Conditions stored fuel and lubricants prior to use or transfer, enhancing system performance and lowering maintenance costs.

Key Benefits

✅ Enhanced Equipment Life: Cleaner oil reduces engine wear, corrosion and deposit formation on critical components.
✅ Lower Maintenance Costs: Fewer oil changes and reduced frequency of system maintenance.
✅ Continuous & Unattended Operation: Built for reliable 24/7 service in marine and industrial settings.
✅ Flexible Integration: Pressure-discharged clean oil can be fed directly back into system circuits or storage.
