Cat Industrial Engines (OEM)
Cat engines have made a name for themselves in prime and backup power applications, in marine vessels, and in the extensive lineup of Cat machines for the earthmoving sector. In addition to these offerings, Caterpillar also supplies engines for industrial applications in displacements from 0.5 to 32 liters. These engines power everything from commercial lawn mowers to wood chippers, rock crushers to specialized tractors, and dredges to pumps and air compressors.

Conventional vs Green Power
Caterpillar diesel engines have made a name for themselves at sea, on highways, and on the rails. But these powerplants are now offered for a range of alternative fuel sources including hydrogen, natural gas, and biogas (cogen being a primary application). Cat engines can also use biofuels like hydrogenated vegetable oil when available. We even offer microgrids which add solar power to the overall energy mix.

Prime vs Standby Generators
Both standby and prime power generators are designed to give your business needed power in the event of an outage or other emergency, but there are slight differences in the meanings of the terms. A standby-rated unit can provide its nameplate power capacity for the duration of an outage, but load should exceed no more than 70% of the nameplate rating over the total course of use. In addition, a standby unit should not run for more than 500 hours a year.
