Easy to transport and install

Our 2500 range engines are easy to transport and install thanks to their exceptional power-to-weight ratios and compact size, and they provide you with excellent service access for ease of maintenance.

Engines in our ElectropaK 2500 range are delivered to you complete with radiator and air cleaner system already built on, enabling you to simply bolt the engine down, connect it up and start generating.

Optimum economy

The mechanically operated unit fuel injectors, with electronic control and carefully matched turbocharging, mean you get excellent fuel atomisation and combustion with optimum economy and low emissions.

These engines give you reliable power, low oil usage and low wear rates. And with their high compression ratios, you can be assured of clean and rapid starting in all conditions.
