The KLEENFUEL ELAIS diesel fuel polishing system is a compact, high-efficiency solution designed to remove contamination from stored diesel fuel, restore fuel quality, and protect engines from failure.

Ideal for marine, industrial, and standby generator applications, this advanced fuel polishing unit eliminates water, sludge, and diesel bug contamination directly from your tank.

 Why Diesel Fuel Becomes Contaminated

All stored fuel degrades over time. This leads to:

• Water contamination from condensation

• Microbial growth (“diesel bug”)

• Sludge and sediment build-up

Without a proper diesel fuel cleaning system, this results in:
 Blocked filters
 Engine damage
 Downtime and costly repairs

 Proven Fuel Polishing Results

The images shown demonstrate a real-world example of heavily contaminated fuel processed through the ELAIS fuel polishing system.

Before:

• Dark, contaminated diesel

• Heavy sludge and debris

• Blocked filtration components

After:

• Clean, bright diesel fuel

• Contamination removed

• System restored to safe operation

This is true fuel tank cleaning — not additives, not temporary fixes.

 Advanced Fuel Polishing Technology

The ELAIS system continuously circulates fuel through a high-performance diesel filtration system, removing:

• Free and emulsified water

• Microbial contamination (diesel bug)

• Fine particulates and sediment

• Oxidation residues and sludge

 Applications

This diesel fuel polishing unit is ideal for:

• Marine vessels and yachts

• Fuel storage tanks

• Backup generators

• Construction and plant equipment

Especially effective as a marine fuel polishing system where contamination risk is high.
