Diesel Fuel Polishing Gauteng

Diesel Fuel Polishing for Generators in Gauteng

Fuel polishing filters stored diesel to remove water, sediment and microbial contamination. It protects your generator from blocked filters, stalling and start failures. Gentec Co performs fuel polishing on site across Gauteng.
  • Diesel stored for many months
  • Filters clog repeatedly
  • Generator starts then stalls
  • Dark or cloudy fuel
  • Water found in the tan
  • Water
  • Sediment and rust particles
  • Sludge
  • Microbial growth

Standby generators often burn little fuel, so diesel sits in the tank for months. Over time it collects water and contaminants that damage injectors and block filters. Polishing cleans the fuel you already have, so you avoid draining and replacing it.

H2: How Fuel Polishing Works

  1. We inspect your tank and fuel condition.
  2. We circulate the diesel through filters on site.
  3. Contaminants are removed and the fuel is returned clean.
  4. We recommend a schedule to keep it clean.
