The GEA Westfalia OTB 9-02-066 is a solid-wall disc-stack centrifugal separator — a type of industrial centrifuge that uses centrifugal force to separate liquids and solids. It’s part of the OTB series of GEA Westfalia separators and is engineered for reliable liquid discharge and solid removal.

GEA Westfalia OTB 9-02-066

Key Features

• Type: Solid-wall disc-stack centrifuge (no internal sludge pump; solids collect in the bowl).

• Liquid Discharge: Efficient and controlled, typically via a single lifter system.

• Maintenance: Hinged hood and solids catcher design make access easier for service and cleaning.

• Drive: Usually driven by a horizontal flange-mounted motor for steady, reliable operation.

• Typical Use: Effective for separating liquids containing solid particles — commonly used where oil or contaminated liquid must be clarified.

GEA Westfalia separators like this operate on centrifugal separation principles that are effective for liquid-liquid, liquid-solid, or liquid-liquid-solid mixtures.

 Marine Department Uses

In marine applications, the OTB 9-02-066 is typically used for:

🔹 Fuel Oil Clarification

• Cleans heavy or marine diesel fuels by removing particulates and sludge before fuel enters engines or generators, helping protect injection systems and improve combustion performance.

🔹 Lubricating Oil Cleaning

• Clarifies lube oils that circulate in engine and gearbox systems, reducing wear and prolonging component life.

🔹 Hydraulic & System Fluid Treatment

• Removes contaminants in onboard hydraulic systems (steering gear, winches, cranes), helping maintain smooth operations.

🔹 General Fluid Conditioning

• Used where onboard fluids need cleaning before reuse or further processing, such as bilge or waste oil pre-treatment (depending on system setup).

Why it’s suitable for ships: Marine environments demand rugged, continuous-duty separators that can handle movement, vibration, and varied feed quality — characteristics that solid-wall centrifuges like the OTB series deliver.

 Industrial Department Uses

In industrial settings, the OTB 9-02-066 serves a variety of fluid separation roles:

🔸 Industrial Oil Clarification

• Cleans hydraulic, gear, compressor, or other process oils by removing solid contaminants, protecting pumps and machinery.

🔸 Fuel Treatment

• Clarifies fuels before combustion or processing in power plants or large industrial engines, helping improve efficiency and reduce fouling.

🔸 Liquid-Solid Separation in Processes

• Used where mixed fluids (e.g., liquids containing sediments or fine particles) need clarification before downstream processing (e.g., chemical, petrochemical, refinery processes).

🔸 Waste Oil Recovery

• Separates usable liquid from waste streams (e.g., reclaiming industrial oils by removing solids), helping with waste reduction and resource recovery.

Industrial users value this type of equipment for reducing maintenance costs, protecting equipment, and improving product or process quality.
