Centrifugal separation is used across industries such as food, pharma, marine, energy, water, and waste treatment. A centrifugal oil separator utilizes centrifugal force to separate solids from a liquid. By drawing out solid particles from the processed fluids, achieves a smoother operation of the engine/application by reducing wear on engine components. Examples includes fuel cleaning for ship engines and extracting biofuels from renewable plant-based sources.
The primary difference between using a centrifugal separator and a GreenOil Filtration unit, lies in the separation technology and the energy footprint. Whereas a centrifugal separator (purifier) uses raw mechanical force to fling particles outward, GreenOil Standard utilizes a patented combination of fine filtration through natural materials and a maintenance-free water separation.
Centrifugal Separator uses high-speed rotation to separate particles and water based on density. This often requires the oil to be heated to approximately 90–95°C to reduce viscosity and ensure effective separation.
GreenOil Offline Filter uses discs of sheep wool compressed into various densities as filter material. Water is removed via a patented built-in water separator without the use of centrifugal force. No heating of the oil is required, which helps preserve the oil’s chemical structure.
Energy: A traditional separator is an “energy consumer” due to heating and motor power requirements. GreenOil claims energy consumption that is 8-10 times lower (typically around 245 Watt compared to several Kilowatts for a separator).
Waste: Separators often produce “sludge” (oil sludge), which is oil-contaminated waste that must be disposed of. The GreenOil system generates no sludge, meaning less wasted oil.
Complexity: Separators have many moving parts that require precise adjustment and regular service. GreenOil is a simpler offline system that operates independently of the main engine and requires minimal crew interaction.
Filtration Level: GreenOil can often filter finer particles (down to very low micron levels) and remove free, emulated water more effectively than standard separators in certain marine applications.
