Fuel Polishing Systems
for emergency generators

Fuel maintenance systems for the operational reliability of your emergency power system

Diesel fuel in emergency power systems ages over time, forms sediment and absorbs water. For operators in industry, data centres, agriculture, chemicals or critical infrastructure, this presents a genuine risk of start-up failure, outages or reduced performance under load.

Fuel polishing systems keep diesel fuel or heating oil in a stable condition over the long term, protect the engine and fuel injection technology, and increase the availability of the entire emergency power supply system – regardless of how long the fuel is stored. Anyone seeking dependable planning should integrate fuel maintenance directly into the new build, operation or retrofit of their emergency power system.

AKO provides proprietary fuel maintenance systems designed for stationary emergency generators. These solutions operate according to the principle of modern fuel polishing systems and safeguard fuel quality during ongoing operation – making a significant contribution to the availability and service life of the entire installation.

Design and performance of AKO fuel maintenance systems

AKO relies on permanently installed systems that continuously or at set intervals circulate the tank contents. Each fuel maintenance system is individually designed to suit tank size, site conditions and operating profile – from compact building tanks through to large-scale industrial storage tanks. Depending on the design, these fuel polishing systems combine:

Multi-stage filtration against particles and sediment
Water separation to prevent corrosion and microbial contamination
Tank recirculation to prevent deposits from forming
Diesel stabilisation for long-term storage life

Applications for fuel polishing systems

Are you wondering whether a fuel maintenance system would be worthwhile for your needs?

Here you can see the reasons most frequently cited by our customers. A fuel polishing system is recommended wherever:

diesel is stored over the long term
high start-up reliability and security of supply are required
large tank volumes are in use
the system only operates in the event of a fault
regular functional testing is required
temperature fluctuations in the fuel can lead to condensation formation

Customer benefits – why operators choose AKO technology

Greater operational reliability
Permanently stable diesel increases the start-up reliability of the entire emergency power system – a critical factor for all sectors with sensitive processes.
Reduced maintenance and repair requirements
A well-designed fuel maintenance system means fewer filter changes, longer service life for the fuel injection technology, reduced susceptibility to faults and lower servicing requirements. This saves time and costs while improving planning certainty.
Longer usable life of the fuel
With continuous fuel maintenance, diesel remains stable over long periods – even with tank volumes in the five- or six-figure litre range.
Seamless integration into maintenance and service concepts
AKO carries out the annual filter change and integrates fuel maintenance into existing maintenance routines.

For the operator, this means one single point of contact throughout the entire lifecycle.
