Generators depend on stored diesel fuel to perform during outages, but without proactive management, that fuel can quickly become a hidden point of failure. At Dale Power Solutions, our fuel services team protect your resilience strategy, keeping fuel clean, compliant, and ready when you need it most.
Diesel fuel, particularly modern low-sulphur blends (FAME), naturally degrades over time. Left stagnant in tanks, it absorbs moisture and creates the ideal environment for microbial growth, often referred to as ‘diesel bug.’ This leads to contamination by moulds, bacteria, and sediment, which can block filters, corrode tanks, and compromise generator performance.
For newer generator sets with high-pressure injection systems, contaminated fuel is especially dangerous. Even minor debris can cause costly damage and, in some cases, invalidate warranties. Regular sampling and maintenance are essential for ensuring reliable operation.
Failing to maintain fuel quality can have serious implications:
Generator failure during outages – putting critical operations at risk.
Escalating costs – neglected fuel may reach a point where polishing is no longer viable, forcing complete replacement.
Environmental and compliance risks – unmanaged contamination can lead to hazardous waste issues.
For sectors such as data centres, hospitals, utilities, and critical infrastructure, the consequences of fuel failure can be devastating.
Our comprehensive fuel services are tailored to your site, fuel type, and operational requirements:
Fuel Sampling & Analysis
We use a structured process to extract and test fuel samples, grading them against industry standards. This identifies early signs of deterioration and informs the most cost-effective course of action.
Fuel Polishing & Cleaning
Where light contamination is found, polishing units filter diesel to restore it to an acceptable standard. By removing water, debris, and microbial growth, fuel polishing extends the life of stored fuel and ensures generator readiness.
Remediation & Replacement
If fuel is heavily degraded, we offer uplift, waste removal, and replacement services. Where possible, we salvage usable fuel, minimising environmental impact and cost.
Fixed Fuel Polishing Units
For continuous protection, we install fixed polishing systems that automatically circulate and filter stored diesel. These units are particularly valued by data centres and National Grid sites, where resilience is non-negotiable.
Clean, reliable fuel underpins the performance of every generator. By adopting regular sampling schedules and installing proactive polishing solutions, organisations can safeguard resilience, reduce long-term costs, and maintain compliance.
At Dale Power Solutions, we provide end-to-end expertise in fuel management to keep your backup power dependable.
