Overview#
The Kohler 300REZXD is a 300-kilowatt LPG industrial standby generator in an enclosed configuration. Rated at 210-300 kW standby depending on voltage, it uses a PSI/Doosan engine paired with a brushless permanent-magnet pilot exciter alternator at 1800 RPM. This unit is EPA certified for both stationary and mobile emergency and non-emergency applications, with hurricane-rated enclosure options featuring 186 mph wind load rating.
Gaseous vs diesel at 300 kW#
At 300 kW, gaseous generators eliminate on-site diesel fuel storage requirements and SPCC compliance. LPG provides clean combustion with lower emissions than diesel and avoids fuel degradation issues. At this power level, propane consumption is significant, so tank sizing and delivery contracts are critical planning considerations for extended outage scenarios.
Our service experience#
PowerGen provides installation, maintenance, and emergency service for Kohler gaseous generators throughout Northern California. The PSI/Doosan engine platform in the larger REZX units is built for the 300+ kW class, and we structure PM programs around annual ignition, fuel system, and coolant inspections with attention to the pilot exciter alternator system.
