Optimal Fuel Quality - Reliable Power | Keeping the Lights on

You want your fuel quality to be optimal. Fuel in excellent condition of course gives the best performance. The combustion is a lot better than when diesel fuel is contaminated and it is also better for the environment. Contaminated diesel emits more harmful substances. Also, water in fuel makes that your engine does not run as well as it could. In addition, water in the tank gives rise to growth of micro-organism, which in turn can clog filters and injectors. Dirty injectors give rise to a distorted injection pattern and increased fuel consumption. It is therefore important that your fuel tank remains completely free of water (water content lower than 70 ppm is best). Njord Filtration has developed a system for this, which ensures that you can get the most out of your fuel. The beauty of our system is that it is flexible. You can let us sample and analyse to check that your fuel is free of water, or you can do it yourself with our sampling and test kits.

Water in fuel tank

Njord Filtration offers a service whereby samples are taken and analysed. We can do this by pulling samples from your tank or use samples taken by you with our sample sets. If analysis shows that the water in the tank is lowering the fuel quality, we can make sure that this water is removed. We can do this for you, or provide you with our equipment with which you can recondition the fuel.

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.
