Fuel Polishing & TANK CLEANING Systems

Purify Fuel and Clean Your Storage Tanks to Prevent Unexpected Engine Shutdown

Fueltec Systems designs and manufactures systems for all fuels: gasoline, ethanol blends, kerosene, jet fuel, and diesel. Commercial fuel polishing systems purify fuel to engine manufacturer’s cleanliness standards by removing sludge, rust, and microbial contamination to less than two microns. Water must be removed to less than 100 PPM. 

Fuel polishing and commercial cleaning of contaminated fuel tanks requires a serious filtration and water separation system. The day’s of old time filters and gravity water separators are over.
