Producing reliable power from 910 kVA to 1500 kVA at 50 Hz, our C32 diesel generator sets are made to meet your mission critical, continuous, standby and prime applications. We've designed each to ISO 8528-5 transient response requirements and to accept 100 percent rated load in one step. Generator sets range from low fuel consumption to low emissions systems. Seismic certification is also available for select models, ensuring you maintain power after unexpected disturbances. Our integrated control system, including ATS and switchgear, protects your power supply and keeps you connected through on-site and remote monitoring options. We offer easy-to-use EMCP control panel options, combining your management and diagnostic tools in one. The EMCP 4.4 controller provides multi-generator set paralleling capability, giving you the ability to add generator sets to match your growing power requirements. Browse a broad range of accessories and bolt-on system expansion attachments. Find flexible packaging to fit unique spatial requirements and environmental conditions. Our C32 generator sets are made for demands, so you can make yours.
