Preventing Diesel Fuel Degradation & Bug Contamination in Standby Plants

Automated multi-stage fuel re-circulation and water coalescing for critical hospital and data center generators.

1. Microbial Contamination in Modern Biodiesel Blends

Ultra-low sulfur diesel (ULSD) attracts atmospheric moisture inside bulk storage tanks. Anaerobic bacteria and fungi form biofilms at the fuel-water interface, generating acidic sludge that clogs 5-micron injector nozzles within seconds of emergency startup.

2. Automated Fuel Polishing Loops

Programmable fuel polishing modules draw fuel from the tank bottom, pass it through magnetic particulate filters, coalescing water separators, and UV biocide chambers, ensuring fuel meets ISO 4406 cleanliness standards indefinitely.
