New Tier 4 Kohler generators ... robust.

Kohler Power Systems has added two new models to its robust line of diesel-powered mobile generators designed to offer flexible options to meet end users’ needs while delivering the company’s quality and reliability.

The 90REOZT4 and 120REOZT4 are Tier 4 Final generator models and are built to withstand the elements, run long hours in prime and standby applications, and meet all EPA (Environmental Protection Agency) emission standards.

“The 90REOZT4 and 120REOZT4 offer quiet and reliable operation while delivering dependable power wherever it’s needed,” says Anne Feudner, product manager for Kohler Power Systems.

“Backed by our premium three-year warranty, the two new models are the sixth and seventh option within our award-winning Tier 4 Final diesel and gaseous mobile generator line-up. And, like all previous models, they’re compatible with our recently launched mobile parallelling box.”

Both the 90REOZT4 and 120REOZT4 are EPA emission certified for non-road use and are equipped with a rugged DOT (US Department of Transport)-certified trailer and patented durable enclosure for easy maintenance. Nothing is attached to the enclosure; all wiring and connections are through the back of the unit, making it easy to remove the entire enclosure for fast engine access. 

Both units use John Deere Tier 4 Final 4.5L engines that help lower operating costs with efficient performance and fuel savings. Kohler’s complete diesel mobile generator line will feature nine models, with the remaining two scheduled to launch later this year.

The 90REOZT4 is capable of a 78 to 85 kW standby rating, 70 to 76 kW prime rating and 62 to 69 kW continuous rating. The 120REOZT4 achieves a 95 to 105 kW standby rating, 90 to 96 kW prime rating and 79 to 89 kW continuous rating.

Both generator models integrate user-friendly features to deliver straightforward operation and dependable performance in the field, which include:
