Fuel Purification

Fuel Purification Facts

Diesel Fuel Purifiers

See the Demo Video

This separator is based on surface tension principle. Since diesel and water have different surface tension as well as density, when a mixture of diesel and water is spread over a large area water droplets and large solids will separate from the fuel.

In fuel water separation, the larger the surface area the better. Dieselcraft separators are engineered for maximum "residence time" based on flow rate. Residence time is a broadly useful concept that expresses how fast something moves through a system in equilibrium. The longer the residence time the better the cleaning.

Dieselcraft utilizes matched flow rate to surface area and activated alumina to get the water to agglomerate and drop out of the fuel.

If a purifier is not matched to the fuel flow you get nothing but more bad fuel and the problem is not solved

All Dieselcraft Purifier designs undergo velocity magnitude simulations to assure performance.

All purifiers are supplied with a water sensors and the needed mounting hardware.

How much water in fuel is OK?

Equipment manufacturers specify that ZERO free water must reach the engine.

Zero water is not realistic. All diesel contains some percentage of water. The most important thing is to keep the water below its saturation point so that it stays dissolved rather than entering your equipment as free water.

Saturation points vary from roughly 50 ppm to 1800 ppm based on temperature and on the petro diesel/biodiesel ratio. When water content reaches the saturation point, the excess water will fall out as free water. Your diesel may hold 90 ppm dissolved water when warm, but only 60 ppm when it cools down due to colder weather. The 30 ppm difference falls out as free water and settles to the bottom of the tank. 

Knowing the water content is important.
