Compact Air-Cooled Power Units: Reliable Engines for Unregulated Territories

Designed for unregulated emissions territories, Lister Petter’s compact power units deliver dependable performance in ambient temperatures up to 40°C. These robust, air-cooled engines reach operating temperature quickly, ensuring efficient, unmanned operation for extended periods. With durable construction and easy maintenance, they offer cost-effective solutions for a wide range of industrial applications.

Key features of our compact power units include:

• Air-Cooled, Direct Injection Design: Naturally aspirated 1, 2, or 3-cylinder engines, optimised for reliable performance and reduced maintenance.
• Biodiesel Compatibility: Can run on biodiesel blends up to 20%, conforming to ASTM D6751 and EN14214 standards—supporting sustainable fuel options.
• Convenient Starting Options: Electric start with an optional hand start for flexibility in various environments.
• Enhanced Cooling Efficiency: Deep crankcase and cylinder cooling fins ensure optimal heat dissipation, extending engine life.
• User-Friendly Maintenance: Self-bleeding fuel system, mechanical governor, and plunger-type oil pump with spin-on filters simplify upkeep, with 250-hour service intervals (dependent on operating conditions).

These durable, easy-to-maintain power units are ideal for remote and demanding environments, providing a reliable solution for continuous operation with minimal intervention.
