The GEA Westfalia OTB 1-02-066 is a solid-wall disc-stack centrifugal separator manufactured by GEA Westfalia Separator, a global leader in centrifugal separation technology. It’s designed to separate liquids and solids using high-speed centrifugal force.
GEA Westfalia OTB 1-02-066
Key Characteristics
-
Type: Solid-wall disc-stack centrifugal separator — meaning it uses a stack of discs and a bowl that spins at high speed to create high centrifugal force for separation.
-
Design: Typically features a hinged hood and sediment collector for easier maintenance and solids removal.
-
Functionality: The machine separates two-phase (liquid-liquid) or three-phase (liquid-liquid-solid) feeds such as oil contaminated with sludge and water.
-
Medium Application: Often used where oil purification or liquid clarifying is needed.
How It Works (Simplified)
-
Feed enters the rotating bowl.
-
Centrifugal force pushes heavier components outward and lighter ones inward.
-
Clean/clarified liquid and separated solids are collected and discharged via specific outlets.
GEA separators offer liquid-liquid, liquid-liquid-solid, or liquid-solid separation, depending on the product and conditions.
Marine Department Uses
In marine environments (ships, offshore units), the OTB 1-02-066 is typically used for:
🔹 1. Fuel Oil Purification
-
Cleans fuel oils before they enter engines and boilers.
-
Removes sediments, water, and sludge to protect fuel pumps, injectors, and combustion systems.
-
Cleaner fuel increases engine efficiency and lifespan.
🔹 2. Lube Oil Clarification
-
Treats lubricating oil used in gearboxes, turbines, and generators.
-
Reduces wear and helps prevent breakdowns by removing abrasive particles and contaminants.
🔹 3. Hydraulic Oil and Auxiliary Fluids
-
Improves the quality of hydraulic and auxiliary system oils, protecting pumps and actuators.
-
Helps reduce maintenance needs and downtime.
🔹 4. General Shipboard Fluid Treatment
-
Can assist as part of oil-water-solid separation systems depending on installation and piping.
-
Works synergistically with other marine treatment systems like bilge separators.
Why it matters on ships:
Marine separators must work reliably in motion and under variable sea conditions — centrifugal separators like the OTB series are robust for such conditions.
Industrial Department Uses
In industrial environments, the OTB 1-02-066 is used wherever liquid purification and clarification are needed:
🔸 1. Fuel & Process Oil Treatment
-
Purifies fuels used in power plants and industrial engines.
-
Removes water, sludge, and particulates before fuel is burned or fed into systems.
🔸 2. Oil-Solid Separation
-
Removes solid contaminants from oils in manufacturing plants, refineries, turbines, and compressors.
-
Helps extend equipment life and reduce maintenance costs.
🔸 3. Liquid Clarification
-
Clarifies mixtures of liquids with suspended solids — applicable in chemical processing, wastewater handling, and oil-based manufacturing.
🔸 4. Supporting Downstream Processes
-
Cleaner liquids improve performance of downstream systems such as filters, heat exchangers, and pumps.
-
Reduces unplanned downtime by reducing clogging and wear.
Maintenance & Monitoring
-
Monitor feed rate, bowl speed, and outlet clarity.
-
Empty sediment collector and clean bowl per maintenance schedule.
-
Regular checks help maintain separation quality.
Benefits & Considerations
Benefits of OTB Series Separators
✔ Efficient removal of water and solids through centrifugal action.
✔ Can handle multi-phase mixtures (oil, water, solids).
✔ Helps extend operational life of engines and industrial equipment.
✔ Useful in space-constrained environments like engine rooms.Considerations
-
Must be sized properly for flow and duty.
-
Must be operated within design limits (temperature, feed composition).
-
Proper maintenance is critical for consistent performance.
