GREENOIL Filtration Systems

Sustainable Oil Particle Filtration and Patented Water Separation

GreenOil Standard ApS are based in Denmark; they design, produce and market a unique series of oil filtration solutions, breaking traditions in which oil cleaning has been performed for decades, mostly with centrifuges.


GreenOil offer a patented oil filtration system for deep cleaning and removing water from any type of oil application.

The most efficient system on the market, maintains optimal oil efficiency.



Since 2008, thousands of filter systems have been installed onboard all types of vessels and ashore in various industrial plants.


Among these ships are the world’s largest container vessels – The Triple-E series.


MAERSK 3E Oil filtration

M/V Maersk Mc Kinney Moller, 1 of 20 Triple-E vessels

These are the world largest container vessels using GreenOil filters.

Onboard each vessel, 10 x GreenOil filters are installed for different applications.


Filters to Replace Existing Separators?

With the development of a unique series of filtration systems for lubrication oil in engines, GreenOil filters are suitable to replace existing separators onboard or in newbuildings.








GreenOil are offering a unique product; they are the only manufacturer on the market, who are able to remove free water particles, emulsified and bound water from any oil type!

GreenOil Performance Vs Centrifugal Separator


GreenOil has conducted several tests in cooperation with engine suppliers, among them MAN Energy Solutions. Here the conclusion was, that GreenOil’s equipment complies with MANs recommendations and requirements for lubricating oil treatment and can be used instead of traditional purifiers/separators.


MAN have given approvals for 2-stroke and 4-stroke Main & Aux. Engines.

 The usage of GreenOil offline filters for cleaning of lubricating oil on two-stroke low speed engines, proves to offer several possible savings:


  • No energy needed for oil preheating
  • Reduced power consumption for the cleaning process
  • Oil waste is reduced to virtually zero
  • Reduced maintenance and operating costs
  • Minimized down time if cleaning equipment
  • Better oil quality



Where can the Filters be Used?


  • Engine – Lube oil on both 2 and 4 stroke engines
  • Propulsion systems as Stern tube, Azimuth and Thruster - including EAL Bio Oils
  • Fuel Oil – Diesel and Marine Gas Oil
  • Gear and Hydraulic power packs
  • Mobile oil filtration and high water removal solutions (emergency)

Key Benefits


  • GreenOil systems clean oil more effectively than even the best centrifuges
  • Short return on your investment, typically within 6 - 10 months
  • 8 - 10 times less energy consumption than a separator
  • No sludge production – no wasted oil, savings from no disposal
  • Clean oil, secure operational reliability and durability!


The necessity for absolutely clean oil is commonly known as good practice. Downtime and repairs may be reduced 5 - 10 times for hydraulic systems, 4 - 8 times for lubrication system oils and oil lifetime may be prolonged by 4 - 8 times. Improved filtration is thus vital to reduce cost, repairs, and downtime. The unique combined GreenOil filter yields a new top class standard for particle filtration.
