Manual/Remote Start– Lister Petter gensets have the flexibility of either manual or remote automatic start.

Low Maintenance Costs – On standard models, fuel filters, air filters, oil filters are all common across our ranges so no need to hold multiple part numbers. Seperate crankcase door allows easy access to the bottom end of the engine without needing to remove the top part of the engine.

Mechanical Governing – On all Alpha engines the governing is mechanical meaning no electrics to diagnose or replace. The simple governing ensures consistant performance of the engine.

Uptime – All lister Petter engines are built to be srong, rugged and reliable. This enables them to be run for many hours ensuring that your application is never unavailable.
