Get a Quote for this Engine
The Hatz 1D81 is built for demanding industrial applications where reliability and service access matter as much as output. The air-cooled design keeps installation simple by removing the need for a liquid-cooling system, making it well suited to compact machinery and equipment that operates in harsh environments.
Performance is strong across common working speeds, with up to 10.0 kW (13.4 hp) at 3000 rpm, plus 9.6 kW (12.9 hp) at 2800 rpm and 9.2 kW (12.3 hp) at 2600 rpm. For governed-speed duties, the 1D81 supports 3000 rpm, and it also suits lower-speed constant operation such as 1800 rpm and 1500 rpm where stable output is required.
