Fuel polishing service overview

Fuel polishing, or fuel cleaning, is essentially a key service for diesel-powered critical applications that eliminates a serious point of failure: fuel contamination. It’s completely non-disruptive and can enable continued use of your fuel whilst we polish it, depending on the severity of the contamination. Read on for more information on how fuel polishing can benefit your business.

Long-term protection of your stored diesel fuel

Our intensive but non-disruptive service can restore your fuel back to optimum quality, making sure you can rely on it when you need it most.

Using state-of-the-art units, our fuel polishing kit can polish up to 25,000 litres of fuel per hour to an industry-best filtration level of micron 1 absolute, restoring your diesel to optimal ISO 4406 standards of cleanliness.

The importance of a fuel polishing system

Imagine the horror of your backup generators failing at a critical moment, or catastrophic equipment failure due to contaminated fuel.

When you rely on uninterrupted backup power, it’s essential that the stored fuel is kept clean to prevent unplanned power failure. Over time, deposits of sludge, sediment and water can build up in stored fuel. If left untreated, the consequences could be catastrophic, ranging from losses in millions of pounds for a data centre to the loss of refrigerated food in a supermarket or even worse, the loss of lives in a hospital.

Fuel that is stored for long periods of time can begin to degrade in quality and become contaminated, which will have a negative impact on a diesel generator or equipment. In worst-case scenarios, this can cause system failures which could be catastrophic, particularly in emergency backup generators. If a fuel test shows that you have contaminated fuel, you can have it cleaned or “polished” to ensure if conforms to EN590 and ISO4406 levels once complete.

As well as avoiding critical failure, fuel polishing improves generator and equipment efficiency as cleaner fuels reduce the amount required for combustion. This leads to lower overall fuel costs and reduced risk of unplanned downtime from breakdowns.

Benefits of fuel polishing

  • It’s a cost-effective, efficient and safe fuel remediation service
  • Eliminates the need for more expensive procedures such as replacing your fuel
  • Improves fuel efficiency and equipment performance
  • Prevents the build-up of sludge and water from entering the engine or generator
  • Fast, effective and completely non-disruptive
  • Secures the future of your fuel supply
  • Increased reliability, which reduces the risk of equipment breakdown

Fuel tank polishing process

To begin, fuel polishing units are attached to the tank in a parallel circuit which means that you can still use your fuel while it’s being polished. Fuel is filtered through increasingly finer filters to remove all harmful contaminants until it’s clean and reaches a filtration level of 1 micron absolute, removing water to 100ppm – an industry best.

Next, the polishing unit uses advanced depolymerisation technology to break down harmful particulates, polishing your fuel to perfection and ensuring it conforms to EN590 and ISO4406 levels.

If required, the tank is then isolated from your system and cleaned, removing any debris which would re-contaminate your fuel. The fuel is tested before it is returned, to ensure it meets industry standards.

Fuel polishing FAQs

How much does fuel polishing cost

Due to its complexity and the highly specialised equipment involved, many people assume that fuel polishing will be expensive. However, it’s actually one of the most cost-effective treatments available when all factors are considered, such as:

  • Lack of disruption to services
  • No need to purchase a new fuel supply
  • Avoids the waste and cost of disposing of a contaminated supply

Most credible providers will typically charge you a fixed fee for smaller jobs, and normally a pence per litre cost for larger volumes of fuel.

How does Crown Oil Environmental’s fuel polishing process work?
  • Polishing units are attached to your fuel tank in a parallel circuit to return your clean fuel as good as new
  • We pump out your dirty fuel and filter it using a series of processes to remove all harmful contaminants
  • If required, we clean the tank and remove any debris
  • Before it is returned the fuel is tested to ensure it meets industry standards
  • We pump the fuel back into your tank
How often should fuel be polished?

Generally, fuel should be tested at least once a year. The results of this will determine whether your fuel needs polishing or not.

A regular proactive maintenance programme will ensure your costly assets are monitored by fuel specialists and help ensure your equipment and generators are running on quality fuel.

Choose Crown Oil Environmental as your partner and have the option of including the cost of fuel polishing as part of your maintenance contract. We’ll regularly check the quality of your fuel and provide a detailed report to recommend and explain your best course of action.
