The Kohler 100RZGD is a 100-kilowatt LPG industrial standby generator in an open-frame (skid-mounted) configuration. Rated at 73-100 kW standby depending on voltage, it uses a General Motors V8 engine paired with a brushless permanent-magnet alternator at 1800 RPM. The open-frame design is typical for indoor mechanical rooms or locations where a separate enclosure or building houses the generator.
At this capacity, gaseous generators eliminate on-site fuel storage requirements and SPCC compliance obligations. Propane offers clean combustion with lower emissions than diesel, and there is no fuel degradation concern during low-runtime standby duty. The trade-off is dependence on propane delivery infrastructure during extended outages.
OnPoint Generators provides installation, maintenance, and emergency service for Kohler gaseous generators throughout Northern California. The GM V8 platform in the RZG series is well-established with broad parts availability, and we structure PM programs around annual ignition and coolant system inspections.

Frequently Asked Questions
What is the standby rating of the Kohler 100RZGD?
The 100RZGD is rated 73-100 kW standby (73-125 kVA) depending on voltage configuration, operating on LPG at 60 Hz.
What fuel does the Kohler 100RZGD use?
The 100RZGD operates on LPG (propane). Natural gas and dual-fuel variants are also available in the RZG line.
What is the difference between RZX and REZX models?
RZX designates the open-frame (skid-mounted) configuration, while REZX is the enclosed (sound-attenuated or weather-protective) version. Both use the same engine-alternator package; the difference is the enclosure.
