20kW Generator Rental (25kVA)

Prime Power Rentals 20kW generator rental (25kVA) provides reliable power to meet the most demanding requirements. They are designed and built to withstand harsh environments at construction sites and provide dependable temporary power at entertainment venues and disaster recovery operations. And to safeguard the environment, the 20kW generator features an integrated 24-hour fuel tank with a fluid containment system.

The 20kW / 25kVA diesel generator offers a prime rating of 20kW (three phase), 14kW (single Phase), and a standby rating of 22kW (three phase), 16kW (single Phase). Output voltages of Three phase (120/208V, 277/480V) and Single Phase (120/240V) are all available. An electronic governor maintains frequency to ± 0.25% from no load to full load. It features an auto start stop that allows the generator to start from a remote location. The unit features an e-coat and powder-coated, weatherproof steel housing that allows a substantially low operating noise level of 65 dB(A). A comprehensive analog & digital control panel provides instrumentation including AC ammeter, AC voltmeter, frequency meter, AC circuit breaker, engine gauges, and much more.
