The Kohler 3250REOZD is a 3250-kilowatt diesel industrial standby generator powered by a Detroit Diesel/MTU 20V4000G83L V20 engine at 1800 RPM. This is the largest model in the REOZ platform, serving the most demanding mission-critical applications. Medium-voltage options (4160V–13800V) are available for utility paralleling and large distribution systems.
OnPoint Generators services Kohler REOZ diesel generators throughout Northern California. Units above 3 MW require the most specialized service capabilities including medium-voltage expertise, MTU V20 engine service, and multi-megawatt load bank testing.
