Clean Fuel Systems™ for Marine
Our original, patented Clean Fuel System™ has been the engineered choice for yacht owners for over 15 years and is now standard equipment or a standard option with 20 yacht builders. Our experienced, degreed engineers and marine industry veterans can help you customize any installation and fulfill engine room design for installers. Our “packaged-system” approach combines unique-in-class components that actively and continuously attack and eliminate the three elements of fuel contamination: water, microbes (or “bugs”) and sediment. For instance, our filtration system is not just a filter, but a specially-housed, pleated device that filters down to an industry-leading 2 microns. Our separation vessel separates rather than absorbs water, eliminating 99.9% of water in the system and readying the waste for clean removal. And our advanced De-bug™ magnetic array permanently removes yeast, algae, fungi and other organisms in a way that is both highly effective and environmentally friendly (no chemical biocides). A continuous-duty, high flow pump agitates tank contaminants, allowing them no place to hide in our system.
The CFS-1000 SERIES offers a wide range of benefits to your vessel.
Additives
Even the cleanest, most refined fuels operating new engines contain hydrocarbons which form agglomerations of gums, resins, and carbon during combustion. This leads to engine problems, less power and fuel efficiency, and engine wear and breakdowns.
ESI provides a product which prevents this buildup from occurring. PRI-D, developed by Power Research Inc., works effectively with the ESI Clean Fuel System™ to inhibit carbon deposits, remove slime and sludge, stabilize fuel and extend its storage life, and prevent tank erosion. In addition, the engine exerts more power more efficiently, and with less smoke.

System Components
ESI systems contain the highest quality components for added reliability. From hoses to fittings and Racor components, ESI provides the appropriate components for your fuel system. Each component has undergone lab testing to ensure reliability.
Complementing the ESI Clean Fuel System™ is the De-bug component, an environmentally safe (no biocides) multi-magnet array, which destroys microorganisms that plague stored diesel fuel. De-bug improves fuel system reliability and performance safely and effectively while reducing maintenance costs.
ESI researches and tests each component and system we recommend. To qualify for the ESI Engineering Approved seal, components and systems must meet high quality performance standards. 
This gives you confidence, knowing that your system is equipped with the best, most reliable components.
Engine Room Design
Custom marine vessels require custom-fitted solutions, and ESI once again leads the industry in designing engine rooms that effectively house an ESI Clean Fuel System™ without compromising the ocean trawler’s architectural appeal. We meet with you about designing the engine room, and we offer the best fuel management solution for you to achieve maximum fuel efficiency and reliability.
ESI is the power behind reliable fuel, and the mastermind behind efficient engine room design. If you have any questions, comments or to discuss your fuel system installation needs, please contact ESI Total Fuel Management.
