16 Compact Equipment JULY/AUGUST 2018 benefit for small machines. Still, compactness and low weight are main features for all of our products." In 1976, Hatz developed its unique silent package, still available today, featuring insulation specially developed for reducing noise emissions by 60 percent in some cases (despite cooling fans). And now, in 2018, Hatz is marking another milestone. "Our new H-Series engines combine all of these components and technologies that we have devel- oped over the years," said Richter-Schützeneder "and it's the first of our downsizing engines." Hatz invited Compact Equipment to its German home to debut its compact H-Series family of off-highway diesel engines and also to talk emissions strategy, its Hatz Smart Parts system and its increasing interest in the North Amer- ican construction equipment marketplace. I toured its extensive factory in Ruhstorf, enjoyed some informative presentations, eked out a little operation time and even drank beer and schnapps with Wolfram Hatz, majority shareholder and chairman of the advisory board at Hatz (also, all-around nice guy). On this side of the pond, Hatz Diesel has been repre- sented in North America since 1969. Today, Hatz Diesel of America Inc. operates sales, engineering, service and engine testing facilities in Waukesha, Wis. Leading these operations is Hatz American president and CEO Mike Har- toonian, and he's looking for more machine makers to em- ploy these H-Series beauties. "The H-Series of engines brings Hatz to markets and applications that we just didn't reach with our previous product offerings," said Hartoonian. "We're approving new applications every day really. We've always been big in the concrete and compact construction equipment businesses, but we are of course looking to expand the types of markets we serve." The H-Series boasts some impressive features to help sell these power plants — higher power output, efficiency and torque from a smaller engine capacity, along with lower weight, lower fuel consumption and lower emissions. Diesel engine manufacturers across the industry are all fo- cusing on getting more power and cleaner power out of a smaller physical package, avoiding aftertreatment as much as possible. And while some of its engines might be getting smaller, the options at Hatz are not. "The power and torque-to-weight ratio are big things we like to talk about but also flexibility," explained Har- toonian. "The flexibility of installation into the applica- tion. Because of the size, because of the weight and be- cause we offer different packages, we can offer different versions, different Tiers, different emissions levels and even enclosed power units. These are all based on the same platform, so we can deliver quickly to an OEM in the con- figuration that will meet their exact specification." The latest arrival in the Hatz H-Series family is the three- cylinder 3H50TIC. This unit's power range extends from 24 to 56 hp (18.4 to 42 kW). In comparison, the four-cyl - inder H-Series 4H50TIC engine, which started production in 2014, has a power range of 49 to 74 hp (37 to 55 kW). Both engines are also available in TI variants (one going up to 83 hp) as a less expensive version without exhaust gas recirculation and diesel oxidation catalytic converters for sales in countries with less stringent emissions regulations. For markets with new and stricter emissions regulations, such as EU Stage V in Europe (we're only Tier 4 Final here in America), Hatz has designed the 3H50TICD and the 4H50TICD. Both these engines are equipped with a diesel particulate filter or DPF (all off-highway diesels require a DPF for Stage V but not for U.S.'s Tier 4), with power out- put figures identical to those of the TIC engine versions.
