Nugen Generators

‘Nugen’ is our name for a new generation of power products (generators) and a new, more flexible approach to developing the best solutions for our clients. Using open architecture principles we have selected ‘best-in-class’ components from world leaders in power generation. So unlike other manufacturers, our machines are fitted with the best part for job – not just the parts supplied by our subsidiaries.

Generator Components

Engines from Kubota, Perkins, Cummins and CAT, controllers from ComAp and alternators from Leroy Somer form our standard packages. But if your project needs a custom solution, we can tailor an engine, controller and alternator package to your requirements.

Generator Design

Developed in partnership with our clients, our generator product design focuses on safety, functionality and longevity. All our machines are fully equipped to minimise deployment delays and additional expense. Easy to operate and fitted with our own sound-attenuated enclosure, your Nugen generator will handle the harshest of conditions.

Whatever your business, whenever you need power, you can rely on Nugen. From a portable single-phase generator to a multi-unit power station, Nugen generators provide you with safe, efficient and cost-effective power solutions. Outlets cater for both single and 3 phase operation. Standard controllers Com-Ap MRS15 – other models optional.
