GreenOil Standard Offline Oil Filtration
Patented offline oil filtration systems that replace conventional separators and purifiers. Combined particle filtration and water separation for cleaner oil, lower maintenance costs, and extended equipment life.
🇩🇰 Danish Innovation ✅ Engine manufacturer Approved 🌿 Eco-Friendly ⚡ Low Power Consumption
ABOUT GREENOIL
The Alternative to Conventional Purifiers
GreenOil Standard, based in Ebeltoft, Denmark, has been delivering innovative oil filtration solutions for over 15 years. Their patented systems effectively remove particles and water from oil systems using a unique mechanical filter design — no moving parts, no sludge production, and no oil spill during filter changes.
GreenOil is the only manufacturer able to remove free water, emulsified water, and bound water from any oil type. Their systems achieve cleanliness levels down to NAS Code 02 and water content down to 30 ppm — far exceeding what conventional separators can deliver.
MAN Energy Solutions has given approval for GreenOil equipment on both 2-stroke and 4-stroke main and auxiliary engines as a replacement for traditional purifiers and separators. TBU is the authorized GreenOil dealer for the Benelux region.

PRODUCT RANGE
Filtration Systems for Every Application
GreenOil offers dedicated filtration systems for different oil types and applications on
board. Each system combines a pump/motor unit, GreenOil filter, and built-in water
separator.
WP-Series – Engine Lubrication Oil
Clean lubrication oil is critical to engine performance, reliability, and longevity. Even small amounts of contamination can cause accelerated wear, reduced efficiency, and unplanned downtime. That’s why modern engines demand the highest levels of oil cleanliness.
The GreenOil solution ensures optimal lubrication oil quality through highly efficient particle filtration and water separation. By removing harmful contaminants, it protects engine components from unnecessary breakdowns, supporting safe, efficient, and uninterrupted operation.
GreenOil Standard provides an effective filtration system suitable for all vessel types and engine configurations, regardless of fuel type. Available for both retrofits and newbuilds, the system maintains oil cleanliness within the specifications set by engine manufacturers—ensuring that no contaminants reach sensitive engine components, and significantly reducing wear, maintenance, and total lifecycle costs.

C-Series – Diesel, MGO and Biofuels
Clean fuel is essential for the reliable and efficient operation of modern engines. Even microscopic contaminants or traces of water can damage the fuel injection system, reduce performance, and lead to unplanned downtime. Maintaining optimal fuel cleanliness is therefore critical to protecting engine components and ensuring long-term operational stability.
The GreenOil solution enhances fuel oil quality through effective particle filtration and water separation, ensuring clean and dry fuel that protects the fuel injection system from premature wear and breakdowns. This supports safe, efficient, and uninterrupted operation across all vessel types.
In addition to meeting or exceeding engine manufacturers’ specifications, our solution offers several environmental benefits — including low power consumption, zero oil spills, and no sludge production. It is a cost-effective investment, with a typical payback period of less than one year in most applications.

A/B/H-Series – Propulsion, Gear and Hydraulic Systems
Thrusters, gearboxes, stern tubes, hydraulic systems, and other vital oil-lubricated components rely on clean and dry oil to ensure long-term performance, reliability, and minimal wear. Water ingress and contamination are common challenges that accelerate corrosion, reduce efficiency, and lead to costly oil changes or unexpected downtime.
GreenOil’s advanced filtration and water separation technology significantly enhances oil cleanliness by effectively removing particles as well as free, emulsified, and bound water. This not only extends equipment service life but also lowers maintenance costs and operational risk. The system is fully compatible with EALs (Environmentally Acceptable Lubricants), which are especially vulnerable to water contamination—making it a sustainable and high-performing solution for both conventional and environmentally sensitive applications.

KEY ADVANTAGES
Why Replace Your Separator with GreenOil?
Oil contamination is responsible for up to 80% of machinery failures. GreenOil ensures your oil is consistently clean and dry, protecting sensitive components and reducing lifecycle costs.

Superior Filtration
Removes particles down to 2 microns using wool discs of different densities. Achieves NAS Code 02 cleanliness — far beyond what centrifugal separators achieve.
Complete Water Removal
Patented water separator removes free, emulsified, and bound water from any oil type — the only system on the market capable of this triple water removal.
Minimal Maintenance
No moving parts, no spare parts storage needed, no oil spill during filter changes. Effortless maintenance without tools. Frees crew for other tasks.
Low Power Consumption
Dramatically lower energy consumption compared to centrifugal separators. No sludge production and no heating required, contributing to greener operations.
Preserves Oil Properties
The filtration process does not affect additives or change the properties of the oil. Removing particles and water actually improves oil quality and extends oil life.
Easy Installation
Compact design connects directly to existing piping. Available for both retrofits and newbuilds. The system operates offline so it can be serviced without stopping operations.
