Refurbished Generators

Professionally refurbished and tested emergency power systems

Refurbished generators are tested, overhauled emergency generators and used generating sets that have been restored to a fully capable condition through intensive technical testing, servicing and repair processes. In industrial applications, they represent an attractive alternative to new systems – particularly where reliability, technical integrity and economic efficiency are essential.

Why choose refurbished generators instead of new ones?

In professional applications, the value of a power supply solution is determined not only by technical performance, but also by investment costs and availability. The market for used and refurbished generators shows that high-quality diesel and standby power systems can still deliver substantial operating life after previous use – in some cases many tens of thousands of operating hours before major overhauls are required.

The selection of a used or refurbished generator depends on operating hours, maintenance history and documentation. A professional assessment of its condition, including the engine, alternator and control system, is essential for long-term operation.

Cost benefits compared with new equipment – often lower acquisition costs with comparable performance
Fast availability – unlike newly manufactured bespoke systems, there are no production lead times
Proven technical integrity – through careful testing, repair work and functional checks before sale
A wide range of output classes – from compact 50 kVA units to large diesel generators for high load requirements

Our expertise in used generators

At AKO, we do not regard refurbished generators as standard used products, but as technical assets with a defined level of quality. In line with the principles of sustainability, this results in a reliable, tested power unit that meets your requirements – both economically and technically.

As part of our services, we can:

technically assess used generators and integrate them into our test facility
carry out targeted repairs and retrofit measures
adapt required components, such as control systems, tanks and silencers
ensure standards-compliant documentation and commissioning
