optimal performance from your systems, ensuring robust and efficient power generation.

Explore the benefits

Extend the life-span of the applications - with 2x or even more

By effectively removing all the water from the oil, our solution doubles or even more the oil's and application’s

life-span. In fact, it reduces the need for frequent oil changes and prevents unplanned operational downtime. This significantly lowers maintenance costs and protects against unnecessary wear on the application.

Service- and maintenance-free

We want our customers to be able to focus on their core business and operations. Our solution is designed for permanent operation without the need of regular

maintenance which reduces the risk of costly and time-consuming issues.

Sustainable solution

Our solution also contributes to a more sustainable operation that protects our environment. Apart from extending the life-span of both the oil and the application, our solution also reduces the consumption of oil, components and CO2 emissions.

Compatible and easy to integrate

Our technology is flexible both in terms of capacity and installation, and is designed for retrofitting existing applications and new systems. The COT Oil Refiner System functions as a bypass solution, fully adapted to your specific application and environment, minimizing both space and impact.


Unlike alternative purification systems, for example separators, tend to be large, expensive, energy- and maintenance-demanding to maintain in continuous operation, our solution is both cost-effective and maintenance-free. With a low initial investment, the COT Oil Refiner System is the most efficient solution for removing all the water from hydraulic, lubrication and transmission systems.

Fast-track your ROI with COT Oil Refiner System

Achieve a return on your investment in just a few months, compared to the industry standard of two to three years, with the COT Oil Refiner System.
