Caterpillar makes a very good generator with great reviews. Cat is famous for manufacturing some of the finest power generators and industrial engines on the market today. With clean diesel engines designed to last for thousands of hours before any maintenance is required, you can rest easy knowing your Cat genset will be there to provide the standby emergency or prime power when you need it most.

US Power & Environment specializes in low-hour used generators from 50 kW to 3000 kW. We offer diesel, natural gas, propane, and electric power continuous and emergency standby generators.
