We strive to be your partner in all aspects of oil filtration, as we deliver environmentally conscious, easy maintainable and economically beneficial solutions.

Environmentally conscious by delivering long lasting results and using surplus sheep’s wool in the as part of the solution, giving you a greener footprint. Every little step helps on the road to sustainability. Easy maintainable by making maintenance of our system a no skill job, where easy access, speed and no excess spare parts are an integral part of the design. Giving you happy chiefs onboard your vessel. Economically beneficial by creating a solution which not only provides a fast return of investment and increases equipment lifetime but lowers downtime and manhours. Consideration for investments and finances has been an integral part of the design process from the beginning.

Clean oil is a necessity, making a reliable oil filtration system a must. Our know-how and hands on experience provides us with a unique insight into the demands of today and of what a filtration system must be able do. Enabling us to create tailormade solutions where functionality is top of mind.

Close customer collaboration and continuous communication are essential elements in our work when designing a greener future. For us, that future starts with proper oil filtration.

Danish Design and Practicality is our DNA

Our origin stems from one man, who has spent most of his life working on green and sustainable solutions, Lars Brejnbjerg. He was part of the team developing the small electrical car Mini-el (known in Denmark as the “Ellert”) in the 80’ies. Later he was headhunted by a local company to find a sustainable solution in maintaining oil quality. However, as he was researching the existing market, he realized that there was no ideal solution for removing water from oil. Therefore, he put all his efforts into developing a new solution, the ideal solution. First particle filtration was accomplished by utilizing natural sheep wool as it features excellent particle retention and high fiber strength. Then water separation was made through an innovation principle, where heat is transferred to the water contamination by indirect heating of the oil surface. Though the original prototype was simple, using a heating element form an ordinary kitchen kettle, the solution proved to be more than 10 times as effective as known evaporation principles in which direct heat was used to warm up the oil. Once field tests were completed, the principles were patented, and by 2008 local investors saw a great opportunity, enabling GreenOil Standard to expand internationally.

As a global brand, our offline oil filtration systems are used across all industries and on every continent, but primarily we filter oil for the marine industry, so we are always proud to see a vessel docking knowing our filtration system is onboard. This only furthers our passion for clean oil, and our commitment to our customers, where we continuously strive for excellence as we research and develop new systems and make improvements to the ones already produced. For every vessel GreenOil Standard can assist in arriving safely at their destination we consider it a job well done, and as our fleet expands with thousands of installations worldwide, we believe close collaboration is our way forward.
