Cutting-edge technology

Among the other benefits of our 1200 Series EP engines are a fully electronic fuel system for superior performance and low fuel consumption.

Industry leading flexibility

Perkins is proud to offer unrivalled flexibility and our EP engines are no exception. A tropical radiator is supplied as standard.

Lifetime of low cost

Fuel consumption on our engines has been optimised for prime power and continuous running applications, making them a clean and cost effective solution. Your running costs are also lowered by the fact that no additional fluids or additives are required to run or maintain your engine.

Hydraulic tappets, multi-vee belts, service free aftertreatment and 500 hour oil change intervals also keep your maintenance costs as low as possible.
