A collection of our thoughts and insights.


The storage of fuel has the constant issue of atmospheric moisture ingression, this is a problem affecting fuel quality.
Storage facilities and the environment heat and cool with solar radiant heat, and together with weather, and the lowering of fuel volumes in storage draw in humidity through its breathers. The hydroscopic nature of fuels raises the moisture content of the fuel allowing bacteria to grow and the combustibility of fuels to become compromised in quality.

Diesel fuel has an inherent quality of lubricity, this comes from the compounds (sulphur and nitrogen) forming a protective layer on metal surfaces required to lubricate the combustion engines fuel pump and protect injectors from wear.

The hydrotreating in the refining process of crude oil to produce distillate, is used to reduce the sulphur content, therefore the hydrotreating process can alter the compounds that produce the occurring lubricity of the fuel.

Fuel contamination is a common occurrence in stored fuel of any volume, its presence is directly resulting from many factors having influence of microbial growth
Most farming machines, boats and infrastructure support machinery are only seasonally required to operate, these sit without operation and little maintenance for extended periods of time. The machines will sit in the sun, sea, and rain through seasons with partially filled fuel tanks or even fully filled. The will be required to start up and be operated for periods of heavy extended use,

Pfmblue has added the ability for the internal operation of the unit polishing fuel to be seen through the body housing.

As can been seen in the image of our GP16B, between the main fluid carrying body of the unit and two powered bodies of the unit, the illuminated “Glow” of the internal operation of the frequencies at work killing the “diesel bug”.

Our original blue indication light is still visible through the blue covers.

Fuel tanks

With the development of fuel types and refinement of engine technologies the issues created by bacterial (Microbial contamination) and moisture causing damage to your engines and fuel delivery systems become more costly. The effect of moisture contaminated fuels mixed with the cocktail of microbes and fungus growth causing operational failures erode the operators profit margin.
