Diesel fuel reconditioning and polishing

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

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
