You can be confident your small enterprise will operate as normal despite any power interruption with Cat® D20, D25, and D30 diesel generator sets. The new 20 to 30 kW models offer reliable power for small standby applications, such as telecommunications, wastewater, small healthcare facilities, and office buildings as well as commercial business, including gas stations, restaurants, and convenience stores.

Remain Open in any Emergency

Erratic weather patterns, from thunderstorms to hurricanes and tornados, are resulting in increasing outages. Small enterprises need reliable backup power to keep operations running smoothly. Whether keeping customers coming in the door, providing critical medical care at a small healthcare facility, or giving students and families services, operations of all sizes need to have access to dependable and affordable standby power.

Those you serve, as well as your employees, rely on your operation to remain open. An outage can have disastrous results, no matter what your business. Restaurants, convenience stores, schools, and shops can risk food spoilage and loss of product. Telecoms could have critical communications interrupted. Wastewater treatment plants may be unable to provide clean and safe water in the event of a power disruption.

The 20 to 30 kW solutions by Caterpillar ensure that you have adequate power to suit the size of your operation and provide reliable backup power to keep working.
