Power units, also known as diesel power units, engine power packs, skid mounted engines, or prime power units, are self contained systems built around an industrial engine designed to deliver reliable mechanical or hydraulic power. These units are commonly used to power pumps, compressors, generators, drilling equipment, conveyors, and other industrial machinery where a standalone power source is required.
