The Caterpillar DE18E3 18 kVA diesel generator set is a compact, rugged standby and prime‑power solution for construction sites, light industrial facilities, and remote locations where stable 50 Hz power is essential.
Built around the proven Cat C2.2 diesel engine, this generator delivers a maximum output of 18 kVA (16.5 kVA minimum) at 50 Hz, with a voltage range of 200–400 V, making it suitable for a wide range of three‑phase and single‑phase loads. The set is designed to ISO 8528‑5 transient‑response standards and can accept a 100% block load in one step, meeting NFPA 110 requirements for critical power applications.
The DE18E3 features USA and EU Stage IIIA / R96‑EUIIIa‑equivalent emissions compliance, turbocharged aspiration, and a cooling system rated for standard ambient temperatures up to 55 °C (131 °F), ensuring reliable operation in harsh environments. It is supplied as a fully assembled, factory‑tested Cat generator‑set package with integrated fuel, control, and mounting components, backed by global Cat dealer support, warranty, and service network coverage.
Typical applications include construction sites, temporary events, small workshops, and backup power for essential loads, where low fuel consumption (around 3.7 L/h at 75% load) and long‑term reliability are key. The unit is designed for easy installation and maintains low vibration and noise levels, making it suitable for both open‑frame and silent‑canopy configurations.
