Fuel Polishing for Utilities & Telecom

Protect Your Standby Generators. Protect Your Customers.

Stored diesel fuel degrades quickly. Fuel polishing restores reliability and ensures your generators start when the grid fails.

Why Fuel Polishing Matters for Utilities & Telecom

Utilities and telecom networks rely on standby diesel generators to keep critical infrastructure online during storms, outages, and peak-load events. Contaminated fuel is the leading cause of generator failure in these environments.

Fuel polishing restores diesel to clean, reliable, NFPA-compliant condition.

The Hidden Problem: Stored Diesel Fuel Degrades Fast

Diesel stored for months or years accumulates contamination that threatens generator reliability.

Common Contaminants in Utility Fuel Tanks

Water from condensation
Microbial growth (“diesel bug”)
Sludge and sediment
Rust and corrosion particles
Asphaltene dropout
Filter-clogging solids

These Issues Cause:

Hard starts
Power loss
Clogged filters
Injector damage
Generator shutdowns during outages

What Fuel Polishing Does for Utilities

Fuel polishing is a multi-stage cleaning process that restores stored diesel to usable condition without draining the tank.

Dieselcraft Fuel Polishing Removes:

99% of water (free and emulsified)
Microbial contamination
Sludge, sediment, and tank bottom water
Rust and particulate matter
Fuel haze and instability

NFPA 110 Requirements for Utilities & Telecom

NFPA 110 requires that stored diesel fuel be:

Tested annually
Maintained free of water and contaminants
Kept in a condition that ensures generator start-up reliability

Fuel polishing is the most effective way to meet these requirements without tank replacement or fuel disposal.

Signs Your Utility Needs Fuel Polishing

Generator struggles to start
Visible water or haze in fuel
Dark or cloudy diesel
Sludge on filters
Fuel hasn’t been tested in 12 months
Tank has been sitting unused
Fuel smells sour or acidic

How Dieselcraft Fuel Polishing Works

Step 1 — Fuel Extraction

Fuel is drawn from the tank bottom where contamination is worst.

Step 2 — Filter-less Purification

Our proprietary purifier removes water and solids mechanically.

Step 3 — Magnetic Conditioning

Breaks apart microbial clusters and sludge for deeper cleaning.

Step 4 — Final Filtration

Fuel is polished to clean, clear, usable condition.

Step 5 — Return to Tank

Clean fuel is returned to the tank, ready for generator use.
