The GEA Westfalia OTA 30-00-066 is a solid-wall disc-stack centrifugal separator built by GEA Westfalia Separator — a specialist in mechanical liquid separation equipment. It’s part of the OTA series of disc centrifuges designed to clarify liquids and remove solids using centrifugal force.

GEA Westfalia OTA 30-00-066

Key Basic Features

• Type: Solid-wall disc-stack centrifugal separator — uses high-speed rotation to separate phases by density.

• Separator Function: Clarifies liquids by separating heavier solids from lighter liquid (e.g., oil).

• Bowl Design: Open liquid discharge and nickel or stainless bowl for good corrosion resistance and separation quality.

• Typical Rated Capacity: Around ~14 000 L/h (~61 GPM) depending on configuration.

• Bowl Speed: ~6 600 rpm.

• Motor: Typically ~10 HP (380/460 V, 3-phase drive).

• Construction: Solid-wall bowl with hinged hood and sediment collector — solids must be removed manually during shut-down/maintenance.

 What “Solid-Wall Disc Separator” Means

Unlike self-cleaning separators that eject solids automatically, solid-wall disc centrifuges like the OTA 30 collect solids inside the bowl and require manual removal during maintenance. They are effective for clarifying liquids with moderate solid contamination.

 Marine Department Uses

In marine applications, the OTA 30-00-066 acts as an oil clarifier/centrifuge to improve fluid quality and protect equipment:

🔹 Fuel Oil Clarification

• Clarifies contaminated fuel oil before combustion in main and auxiliary engines and generators, improving combustion efficiency and protecting fuel pumps/injectors.

🔹 Lube Oil Cleaning

• Removes solid particles and sludge from engine and gearbox lubricating oil, reducing component wear and extending service life.

🔹 Hydraulic Oil Purification

• Cleans hydraulic fluids used in steering gear, winches, cranes, and other deck machinery — extending the life of pumps, valves, and actuators.

🔹 General Shipboard Fluid Conditioning

• Keeps various onboard oils (generator, boiler, auxiliary systems) clean and reliable during long voyages or heavy duty operation.

Why it’s used on ships:
Marine separators must operate reliably under motion, vibration, and variable feed conditions. Centrifugal disc designs like OTA are robust and compact, making them suitable for engine rooms and fluid treatment systems.

 Industrial Department Uses

In industrial settings, the OTA 30-00-066 is used in many fluid clarification and purification roles:

🔸 Industrial Fuel Treatment

• Clarifies diesel and other heavy fuels before use in generators, turbines, or industrial engines — improving combustion and reducing nozzle clogging.

🔸 Lubricating & Process Oil Cleaning

• Removes solids and contaminants from hydraulic oils, gearbox oils, and other lubricants used in manufacturing and processing equipment.

🔸 Liquid-Solid Separation

• Used in chemical, petrochemical, and refinery processes where liquids must be clarified before further processing or reuse.

🔸 Waste Oil Recycling & Clarification

• Helps recover usable oils from contaminated waste streams by separating solids, reducing disposal costs and environmental impact.

Industrial applications value such centrifugal clarifiers for protection of equipment, improved fluid quality, and reduced maintenance costs.

Benefits

Primary Benefits

• High clarifying efficiency: can process large liquid volumes at ~14 000 L/h.

• Robust, simple design: ideal for continuous service in engine rooms and industrial plants.

• Wide applicability: useful across fuel, lubricant, process oils, and other liquids.
