Versatile in Use

Hatz Open Power Unit – A Complete Solution from the Manufacturer

As successfully established in the market with the H-series, Hatz also offers the F-series as a robust off-highway OPU, where all components are assembled by Hatz specialists, eliminating the need for any assembly work by the machine manufacturer.
All components – from the cooling system, fuel system, and electrics to the combustion air system – are designed to withstand the toughest environmental conditions, including high temperatures, high dust levels, or high-pressure cleaning. With the OPU developed and produced in Germany, you can be confident in its performance across all applications.

World-Class Service for the Complete Engine System

With the OPU from Hatz, our customers enjoy a unique advantage: we not only offer an optional warranty of up to five years for the entire system but also provide worldwide access to spare parts and services. With over 500 Hatz service centers, we can repair the complete system quickly and efficiently. For our customers, this means maximum convenience – one central contact person ensures clarity and accountability at all interfaces.

Conservative-innovative engine for a long service life

All mechanical components were designed and developed with a conservative-innovative approach. The Hatz H-series therefore has two valves per cylinder, which achieves high efficiency, mechanical robustness and functional simplicity. This – as well as the exclusive use of premium products for all important components – leads to the long service life customary from Hatz.
