Hatz: The German Specialist in Reliable Industrial Engines
Hatz: The German Specialist in Reliable Industrial Engines
Guaranteed Performance in the Toughest Conditions
Motorenfabrik Hatz is a renowned German manufacturer that has specialized in designing and producing compact industrial diesel engines for over a hundred years. The Hatz brand is an absolute synonym for reliability and longevity, especially when it comes to its legendary single-cylinder, air-cooled engines. These simple yet extremely durable units power a vast portion of light construction equipment worldwide, operating flawlessly in dust, dirt, and extreme temperatures.
Whether you own a compactor with a classic Hatz engine or a machine with a modern H-series unit, proper service is key to their long-term operation. Our offer includes a full range of spare parts for Hatz engines.
History: 140 Years of Innovation in a Compact Form
- Beginnings (1880): The company was founded by Matthias Hatz as a craft workshop, and in 1904, it began producing internal combustion engines.
- Diesel Pioneer (1918): Hatz was one of the first German manufacturers to bet on the developing diesel engine technology for industrial applications.
- A Revolution in Lightness (1950): Hatz introduced the world's first single-cylinder, air-cooled diesel engine made of light alloy. This innovation revolutionized the small machinery market.
- Common Rail Era (21st Century): To meet the latest stringent emission standards, Hatz developed the modern H-series, bringing Common Rail technology to the smallest industrial engine segment.
Main Hatz Engine Series
Classic Air-Cooled Series: The Job Site Legend
These are the engines that built the Hatz global reputation. Simple, fully mechanical, and extremely resistant to harsh conditions and service neglect.
- B-Series (e.g., 1B20, 1B30, 1B40, 1B50): A more modern generation of single-cylinder "classics." Used in almost every type of light equipment. Their simple design makes them extremely easy to maintain.
- D-Series (e.g., 1D81, 1D90): Nicknamed "SUPRA," these engines feature a single overhead camshaft (OHC) design, offering higher power and smoother operation.
- E-Series (e.g., E75, E79): Historic, incredibly simple, and durable units still found in older but functional machines.
Modern H-Series: Compact Power for the Future
Hatz's answer to Stage V emission standards. They are the world's first compact diesel engines (under 19 kW) with Common Rail injection and turbocharging.
- H50 (e.g., 3H50T, 4H50TIC): 3- and 4-cylinder liquid-cooled engines. They are characterized by compact dimensions, high power, and meet emission standards without needing a DPF, which significantly simplifies operation.
In Which Machines Do Hatz Engines Work?
Hatz engines are the preferred choice for manufacturers of high-quality, light construction equipment. Their design is exceptionally resistant to vibrations and dust.
- Single-direction and reversible plate compactors: Bomag, Wacker Neuson, Weber MT, Ammann.
- Vibratory rammers (jumpers).
- Small rollers, generator sets, and light towers.
- Water and sludge pumps, and concrete and asphalt cutters.
Company Size and Market Position
Hatz is a global leader in the premium segment of industrial diesel engines up to 83 kW. The company produces around 50,000 engines annually. Its position is based not on mass production but on its reputation for delivering the most reliable and long-lasting engines in its class.
Innovation and Future
Hatz's innovation lies in the continuous improvement of compact and reliable solutions.
- Hatz SILENT Technology (1978): The development of sound-dampening enclosures was a revolutionary response to growing noise regulations on job sites.
- The Modern H-Series: Introducing Common Rail technology to the sub-19 kW engine segment combined legendary durability with low emissions, and the absence of a DPF is a huge advantage for operators.
- Digitalization (Hatz Connect): The company is developing telematics systems that allow for remote engine monitoring, service planning, and diagnostics, a step towards modern fleet management.
Interesting Facts
- "Downsizing" before it was cool: From the beginning, Hatz focused on creating the smallest engines with the highest possible power and durability.
- Tested in extremes: Equipment manufacturers choose Hatz engines because they know they will survive the worst treatment from operators.
- German quality from A to Z: The entire process – from design and casting to final assembly – takes place at the Hatz factory in Germany, ensuring the highest quality control.
Is your construction equipment powered by a Hatz engine? That's a guarantee of reliability worth maintaining.
We provide professional support in selecting parts for all Hatz engine models. Our offer includes high-quality REDX filters, complete overhaul kits, and other components to keep your machine running without downtime for years to come. Contact us!
