The Kohler 10REOZDC is a 10-kilowatt diesel commercial standby generator powered by a Yanmar engine at 1800 RPM. It is the smallest unit in the REOZ diesel lineup, designed for small commercial facilities, retail locations, and light institutional applications where diesel fuel independence is required. The unit features a brushless wound-field alternator with PowerBoost excitation and sustained short-circuit capability up to 300% of rated current.
OnPoint services small diesel standby generators across Northern California for commercial customers who need fuel-independent backup power. The compact Yanmar platform in the 10REOZDC is reliable and straightforward to maintain, with standard annual PM covering oil, filters, and coolant inspection.
