Fuel quality management for standby generators.

Diesel sitting in a tank degrades long before the day you need it. We inspect, test and recondition stored fuel in place — so your generators start when everything else stops.

“Having a solid fuel management plan in place can make the difference during a disaster.”

01 — The risk

What building & facility managers need to know

Conventional diesel storage tanks are not sealed environments. Heat, stagnancy and moisture work continuously against the fuel your business continuity plan depends on.

The onus sits with you. Generator manufacturers demand clean fuel per ASTM D975 and ISO 4406 — responsibility for meeting that falls on the building owner or facility manager.

  • A

    Performance impact

    Poor fuel quality directly undermines your business continuity plan, operational reliability and generator performance.

  • B

    Technical risks

    Water contamination, microbial growth and fuel degradation clog filters and can cause engine failure — a heavy OPEX hit in repair costs.

  • C

    Compliance

    A structured approach with frequent reviews of your emergency fuel policies keeps them aligned with real operational needs.

  • D

    The solution

    Regular monitoring and scheduled maintenance — sampling, testing and polishing — keeps fuel in top condition without taking the tank offline.

02 — Our solution

Diesel Fuel Reconditioning Services

Fuel is drawn from the lowest point of the tank, filtered, polished and stabilised, then returned — while tank cleaning runs concurrently. The generator stays available throughout.

    Collection

    Stored diesel is suctioned from the bottom of the tank, where most contaminants deposit.

  2. 02

    Filtration

    Macro-sized contaminants — water, organic waste, sludge — are filtered out first.

  3. 03

    Polishing

    Filtered diesel is polished to eliminate micron-sized particles and stabilised while tank cleaning runs.

  4. 04

    Efficiency

    Fuel never leaves the storage tank, ensuring zero downtime for generators during the process.

03 — Operational framework

Our procedure

Every engagement starts with evidence. Sampling and testing decide the route — routine monitoring or full reconditioning.

Sampling
Testing (visual or lab analysis)
Low risk
Repeat sampling in 3–6 months
High risk — contaminated
Reconditioning process
Optional comparative testing (visual or lab analysis)

Proposed maintenance schedule

Service Frequency Key criteria
Fuel quality inspection, testing and sampling 3–6 months Water level, microbial growth, degradation and sludge
Fuel polishing and tank cleaning 6–12 months Water level, microbial growth, degradation and sludge

04 — Accountability

Every job closes with a certificate of analysis

Results are documented against ASTM D975 — water and sediment, density, particulate counts, microbial contamination, flash point and visual appearance — so you have an auditable record for your compliance file, not a verbal assurance.
