Overview#

The Kohler 60REOZK is a 60-kilowatt diesel commercial standby generator powered by a Kohler diesel engine at 1800 RPM. It is the largest model in the REOZK series and serves commercial facilities, healthcare, education, and government applications. The unit features a 4-pole rotating-field alternator with Fast-Response permanent magnet excitation, low coolant level shutdown protection, and is available with weather-protective and sound-attenuated enclosures rated for 186 mph wind loads.

Our service experience#

OnPoint services Kohler REOZK diesel generators across Northern California. The 60REOZK is the top of the Kohler-engine REOZK range, and we find it commonly installed in mid-size commercial buildings, schools, and municipal facilities that need reliable diesel standby without stepping up to the larger John Deere-powered REOZJ platform.
