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.
