Hatz 3H50T – compact power package for Stage V machines

Motorenfabrik Hatz presents the newest member of the H-series with the 3H50T three-cylinder industrial diesel engine. High torque and EU Stage V compliance characterise the compact engine.

Motorenfabrik Hatz introduces its new liquid-cooled three-cylinder diesel 3H50T in the Fan-to-Flywheel version as well as in the OPU (Open Power Unit) variant.

The new engine model in the performance class under 19 kilowatts extends the product range of H-series engines that were specially developed by Hatz for current and future requirements on power, performance, reliability and international exhaust gas standards. With a displacement of only 1.5 litres and a maximum output of 130 Newton metres the Hatz 3H50T is the engine with the highest torque in its class in the market today.

The Hatz 3H50T achieves its output without an intercooler. Its very compact construction without diesel particulate filter (DPF) gives significant benefits particularly for use in compact machines. With its low weight and small installation dimension the performance data of the engine even exceeds many older engines in the 19 to 37 kilowatt class. This gives many machine manufacturers an outstanding alternative for planning their compact machines with small engine compartments and for reasonably upgrading existing machines to EU Stage V – with simultaneous safeguarding of previous investments in design and development.

Stage V also without space-consuming DPF installation

The new Hatz 3H50T engine satisfies current and future emission regulations, also including EU Stage V as well as EPA Tier 4 final. Due to its modern design and construction the engine achieves the specified values even without an additional diesel particulate filter (DPF). This predestines the engine for compact machines with restricted space conditions in which a diesel particulate filter is not possible, for example. The Hatz 3H50T emits an extremely low particle mass that also achieves only a tenth of the limit value without any further exhaust emission after-treatment such as exhaust gas recirculation or diesel oxidation catalyst, for EU Stage V this is 0.4 grams per kilowatt hour.

Turnkey OPU solution

The Hatz 3H50T OPU is a plug and play solution that is the ideal choice particularly for manufacturers of compact machines that need engines fully ready for installation. Major examples of use include lifting platforms, hydraulic systems, drilling machines and stationary applications such as pumps and alternators. With its integrated and optimal design of the radiator, hoses and cabling as well as the electronics, the Hatz OPU concept greatly simplifies design and installation.

Genetically without doubt an H-engine family child

During development of the 3H50T, Hatz consistently followed the H-series engine strategy of rightsizing that incorporates state-of-the-art materials and technologies such as turbochargers and the Bosch common rail system (off-highway version). The result are compact and robust engines that feature high torque at low speed.
