Diesel Fuel Centrifuge

Rust sediment and sludge from storage tanks contaminate diesel fuel. Condensation in tanks causes water contamination. Alfa Laval diesel centrifuges separate all the solid particles & moisture from diesel fuel. Clean diesel fuel is essential for the trouble-free operation of engines.

Contaminant-free fuel is essential for reliable engine performance. Alfa Laval diesel fuel centrifuges are designed to protect your engine room equipment by maintaining a clean diesel supply.

They have proven their efficiency and reliability and have been used worldwide for decades. These Alfa Laval diesel centrifuge modules keep the diesel fuel clean when installed between the storage tank and the day tank.

For heavy fuel and crude oils, Dolphin Centrifuge supplies a wide range of self-cleaning fuel purifiers. These are available as separate modules and include per-heaters and starter and PLC control panels.

A recent application using diesel fuel purifier for large scale black diesel recovery was supplied by Dolphin using Alfa Laval disc stack centrifuge (self-cleaning type).

How does a diesel centrifuge work?

Diesel centrifuge operation can be simply explained as follows. Under the extremely high centrifugal force inside the rotating bowl, the water & sludge are spun out towards the outer periphery of the centrifuge bowl while the clean diesel moves inwards and is continuously discharged through a 'light-phase' outlet.

The water is collected and discharged through a separate passage from the bowl periphery. The separated sludge is periodically ejected by the 'self-cleaning' mechanism built into the bowl.

Diesel Purification on Work-boats

Small foot-print Alfa Laval diesel centrifuges are designed for fuel & engine oil purification on vessels such as tugs, barges, yachts, etc.

Typically installed on day-tanks, these centrifugal diesel purifiers remove the water and sediment contamination supplying clean fuel while keeping the lubricating oil clean. 

Shown at the bottom are diesel centrifuge packages of different capacities featuring Alfa Laval centrifuges.
