Description
Product Overview
The Lister Petter GW3 is a robust variable‑speed industrial engine offering continuous output of 28 kW at 1,500 rpm and up to 33 kW at 1,800 rpm. Part of the Gamma series, this engine is engineered for industrial, pump, and generator set applications in unregulated emission zones. Built for durability and reliability, it suits ambient conditions up to 45 °C and starts reliably down to −25 °C.
Key Features
- Variable Speed Range: Optimized for 1,000–2,200 rpm operation depending on application
