Optimal Fuel Quality - Reliable Power | Keeping the Lights on

Keeping your fuel tank clean and free of micro-organism is of great importance. After all, your fuel does not perform optimally when it is contaminated. For long contaminated fuel was seen as a fait accompli, but with the proven cleaning technology of Njord Filtration you always get the most out of your fuel and engine. Our tank cleaning will make sure that you achieve a much better performance with your fuel!

Cleaning tank

A tank cleaning is a job that we can perform for you, but you can do it yourself with our special equipment. It is primarily important that the diesel is properly analysed so we can see what kind of pollution has affected your diesel. This can be bacteria or other micro-organism, but cleaning tank is also needed when there is sediment or emuslified water in the tank. Analysing your fuel can be performed by our professional staff, but you can also use our test kits. Once you are sure that your fuel is contaminated, we get to the next step: cleaning the tank. We have extensive experience in the cleaning of fuel tanks and happily use this experience to serve you well. If you prefer performing this cleaning yourself, then we can supply the necessary equipment.

Keep your fuel clean

Is the fuel clean? Perfect! The issue is now to keep the fuel in optimal condition. Tank cleaning is a job that you need to perform frequently to ensure that you can continue to efficiently use your diesel. Here you have the option to sign a maintenance contract with us, so that we can monitor the quality of diesel. This is done thoroughly by our staff. Even within a maintenance contract it is possible that you sample the fuel yourself to monitor fuel quality. We would then come into action when the fuel is contaminated. Njord Filtration is a young company that offers cleaning technology for multiple types of fluids. It is our mission to do this in an environmentally friendly manner and to develop new technologies, products and solutions. With this we want to ensure that the quality of your fuel remains optimal.

In addition to monitoring of fuel quality through regular sampling, we also offer automated fuel polishing and filtration systems that perform a maintenance run on your fuel weekly.

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.
