Optimal Fuel Quality - Reliable Power | Keeping the Lights on

In order to get maximum return from your fuel, you must ensure that it is always completely clean. Contaminated fuel results in clogged filters, polluted injectors and pumps, ignites more difficultly and creates more harmful emissions. In the interest of your bottom line and the environment Njord Filtration has developed a method to keep all fuel clean and in optimal condition. Therefore, please feel free to visit our website where we explain how Njord Filtration works.

Cleaning the fuel tank

What is really involved in cleaning the fuel tank? Our method can be divided into several steps. In step one, we will check that your fuel tank is indeed contaminated, and by what. The contamination may be due to the activity of micro-organism, by water, but also the natural sedimentation process in diesel produces many problems. In the next step, the fuel and tank are cleaned. The contamination is removed so the fuel can render an optimal performance. In step three, the quality is monitored, as diesel contamination will reoccur when left alone. In addition to the monitoring of fuel quality through regular sampling, we also offer automated fuel filtration systems that maintain your fuel weekly. The final step involves the installation of in-line quality measurement instrumentation for your fuel.

Cleaning the fuel tank yourself

At Njord Filtration, our experienced personnel can perform the tank cleaning process, but it is also possible to do all these steps yourself. After all, when you want to clean for instance your boat's fuel tank, you can easily carry it out with our equipment. Our method is fully scalable to the size your wishes and requirements. You can freely contact us if you wish to discuss what we can do for you. You can do this by phone or by e-mail.

Problem Solver

Our solution


If there are problems with filters, injectors, pumps or diesel quality in general, it is advisable to take a bottom sample from the tank(s) and have it analysed. Sometime the diesel is so filthy that the conclusion is obvious: the diesel must be cleaned.

We offer a sampling and analysis service as well as sampling sets to take your own samples. These can also be sent to us for analysis, or can be tested for microorganisms with Liqui-Cult.


If contamination of the diesel with water, sediment and/or microorganisms is discovered, it is important to remove the contamination from the tank(s) and to bring the fuel back into optimal condition.

To this end we offer a tank and fuel cleaning service as well as the equipment to recondition the fuel yourself. If we clean the tank and fuel, before and after samples are taken to demonstrate the effect of service provided.


After the contamination has been removed, it is usually best to ensure that it cannot reoccur. With modern diesel, however, the chance of this is relatively high. There are a number of preventative measures, products and systems available for this. The choice for one of these is different for each situation, client and available budget.

We offer sampling services, complete fuel maintenance contracts and installation of preventative products and systems according to the KIWA BRL-K903-08 norm.
There are a number of options for the tanks as well as the engines/burners:


If so desired, the quality of the fuel with regard to water and sediment levels can be measured in-line in order to control the quality or to adjust the filtration system.
