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

Why It Works Better Than Traditional Filtration

Dieselcraft uses a filter-less Stage 1 purifier that removes water and solids mechanically, preventing filter clogging and reducing operating costs.

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.
