Developing Solutions.
Ensuring Readiness.

Reliable Defence Technology
Partner from Europe

We see ourselves not only as an engine manufacturer, but as a comprehensive partner for engines, systems, energy solutions, and precision components. From bare “fan-to-flywheel” engines to fully integrated solutions incorporating cooling systems, weather-protection enclosures, sound attenuation, intelligent controls, and customized energy systems, Hatz delivers solutions tailored to each customer’s specific operational requirements. Rather than offering off-the-shelf products, we develop dependable technology engineered for the application and designed to perform where it matters most.

Alongside our engine and systems expertise, Hatz manufactures high-precision components and assemblies for demanding applications. Together, our business units provide customers with reliable technology, manufacturing excellence, and end-to-end support that combine performance, efficiency, and long-term reliability.

Energy & Systems

Mission-Ready Systems

Hatz systems combine durability, fuel efficiency and intelligent power management in compact, mission-ready packages. Designed for vehicle integration or autonomous operation, rapid deployment and long service life, Hatz solutions support defence forces wherever infrastructure is limited and reliability is critical.

Engineering & Testing

Driving Machine Development Forward

Hatz helps customers accelerate development, optimize processes and improve operational reliability with intelligent electrification, testing and digitalization solutions.

Reliability Under All Conditions

Our drive solutions, power generators, and pumping systems are specifically engineered for operation under the most demanding conditions. Whether facing extreme temperatures, limited infrastructure, or fluctuating fuel availability, these systems ensure continuous operational readiness.

Cold-start capability and reliable operation at temperatures exceeding 50°C form the foundation of maximum field reliability. At the same time, their fuel-efficient design reduces consumption and extends operating cycles.

Robust. Autonomous. Mission-Ready.

Air-cooled single-cylinder solutions offer significant advantages in terms of maintenance requirements and operational reliability. In addition, integrated manual-start capability provides an emergency backup, ensuring that systems can be started at any time under critical conditions – independent of any external power supply.

NATO-Compliant When It Matters

Selected products comply with relevant NATO standards and are designed for operation with approved NATO fuels, including F63, F34 (JP-8), and F35 (JP-1). As part of demanding qualification procedures in accordance with AEP-5, a continuous endurance test of 4.5 hours was successfully completed, among other evaluations.

These certifications demonstrate the operational readiness of systems classified under these standards in realistic field conditions.

Fuel Flexibility – Security of Supply

The ability to operate on different fuels is becoming increasingly important. Our systems are prepared to meet growing requirements for fuel flexibility, enabling a wide range of operational scenarios.

Efficient fuel consumption and reduced dependency on specific fuel sources actively contribute to strengthening resilient supply chains – a decisive factor in modern operational environments.

The Extremely Compact Way of High-End Power Generation

The flywheel-integrated permanent magnet generator (fiPMG) is suitable for use in hybrid systems, as an emergency generator or for continuous power supply. As a very compact and lightweight solution, the Hatz fiPMG with the single-cylinder engines 1B30E and 1B50E integrates user-friendly into machine design.

Compared to conventional engine-generator units, the Hatz fiPMG design is significantly more compact, shorter, and lighter. The contactless PMG system achieves an efficiency of over 85%, delivering highly efficient and reliable power generation in a space-saving package.
