The GEA Westfalia OTB 18-02-067 is a solid-wall disc-stack centrifugal separator manufactured by GEA Westfalia Separator, a major global provider of centrifugal separation equipment for oil and fluid treatment applications.

GEA Westfalia OTB 18-02-067

Basic Characteristics

• Type: Solid-wall disc-stack centrifuge — designed for liquid-solid and multi-phase separation using centrifugal force.

• Bowl Design: Disc stack for high separation efficiency — separates heavier solids from liquids by spinning at high speeds.

• Liquid Discharge: Typically uses a single centripetal pump to take the clarified liquid out.

• Maintenance Features: Often built with a hinged hood and a sediment collector, making access and cleaning easier.

• Drive: Usually driven by a vertical flange-mounted motor.

• Main Function: Clarifies or purifies liquids by removing solids and contaminants to produce cleaner liquid suitable for continued use.

This type of centrifuge is part of GEA Westfalia’s broad technology offering for centrifugal separation, which is used across industries to treat liquid mixtures with different densities.

 Marine Department Uses

In marine environments, the OTB 18-02-067 separator is valuable where fluid cleanliness affects safety, reliability, and performance. Marine applications typically include:

🔹 Fuel Oil Clarification

• Before fuel oil is burned in marine propulsion engines or auxiliary generators, it must be free of solid contaminants. The OTB separator removes particulates and sludge, helping prevent injector and fuel pump damage.

🔹 Lube Oil Cleaning

• Lubricating oils used for main engines, gearboxes, and auxiliary machinery benefit from separation of solids, which reduces wear and maintenance frequency.

🔹 Hydraulic & System Oil Treatment

• Hydraulic oil used in steering systems and deck machinery must be free of debris to avoid pump and valve failures.

🔹 General On-Board Fluid Conditioning

• Ensures other oils and fluids used around the vessel (e.g., generator lubrication, auxiliary systems) stay clean and do not compromise operation — particularly vital on long voyages where reliability matters.

 Industrial Department Uses

In industrial settings, the OTB 18-02-067 is used wherever the removal of solids from liquids improves process efficiency, equipment life, or product quality:

🔸 Industrial Oil Clarification

• Removes particulate contaminants from lubricants, hydraulic oils, and coolants used in production equipment, reducing machine downtime and maintenance costs.

🔸 Fuel & Process Oil Cleaning

• Clarifies diesel and other industrial fuels before use in turbines, engines, or burners, improving combustion efficiency and protecting downstream equipment.

🔸 Liquid-Solid Separation in Processing

• Used in chemical, petrochemical, and manufacturing plants to clarify liquids that contain suspended solids before further processing or disposal.

🔸 Waste Oil Reconditioning

• Helps reclaim reusable oils from contaminated streams by separating solids, reducing disposal costs and improving environmental compliance.
