The Alfa Laval MIB 303S is a compact, high-speed disc-stack separator designed specifically for the purification of mineral oils, including marine diesel (MDO), distillate gas oil, and lubricating oil.
Unlike traditional separators, the MIB 303S Alfa Laval oil water separator features a design that balances high separation efficiency with an extremely small footprint.
MIB 303S has a Direct Drive technology. The motor is mounted directly on the bowl spindle, eliminating the need for a gearbox or belt drive.
This reduces mechanical friction, lowers power consumption, and significantly decreases the number of wearing parts, resulting in a unit that is exceptionally reliable and easy to maintain.
The solid-wall bowl keeps the separated solids inside for manual removal rather than automatic discharge, simplifying the mechanical design and reducing long-term maintenance requirements.
The “S” designation highlights a simplified, robust configuration focused on continuous stability. Utilizing a solid-wall bowl, the MIB 303S retains separated solids for manual removal.
This straightforward approach simplifies hydraulic discharge systems, making it the ideal “plug-and-play” solution for vessels and plants with limited space or manpower.
Alfa Laval MIB 303S Key Features
- Direct Drive System: The motor connects directly to the bowl spindle, eliminating gears and belts. This reduces vibration, minimizes power loss, and removes the need for gear oil changes.
- Compact & Lightweight: Designed for tight spaces, its small footprint allows for easy installation on smaller vessels or in crowded engine rooms where traditional separators won’t fit.
- Solid-Wall Bowl Design: A fail-safe manual cleaning system that retains sludge within the bowl, reducing the risk of mechanical error associated with automatic discharge mechanisms.
- Flexible Operation: Easily convertible between purifier mode (separating water and solids from oil) and clarifier mode (removing solids only), ensuring versatility for different oil grades.
- Low Maintenance Requirements: With fewer moving parts and no gear transmission to maintain, downtime and spare parts costs are drastically reduced.
Alfa Laval MIB 303S Applications
- Marine Fuel Treatment: Essential for polishing Marine Diesel Oil (MDO) and Gas Oil on coastal vessels, workboats, and superyachts to protect engines from water damage.
- Auxiliary Engine Lubrication: Keeps lube oil clean in auxiliary generators and thrusters, preventing bearing wear and extending oil life.
- Power Plant Gensets: Provides continuous purification for diesel generator sets in land-based power plants, ensuring startup reliability.
- Industrial Fluids: Efficiently removes contaminants from hydraulic oils and coolants in manufacturing and mining equipment, preventing system failures.
