Caterpillar DE13.5E3 13.5 kVA Diesel Generator

The Caterpillar DE13.5E3 is a 13.5 kVA diesel generator set built around the Cat C1.5 engine platform, engineered for robust performance and long‑term reliability. It delivers stable 50 Hz alternating current at 200–400 V, making it suitable for single‑ and three‑phase applications such as small workshops, agricultural operations, construction sites, and emergency backup power for offices or housing.

This generator is designed to ISO 8528‑5 transient‑response requirements, ensuring tight voltage and frequency regulation during load changes for sensitive equipment. The unit typically features a heavy‑duty fabricated‑steel base frame, integrated fuel tank, and a weather‑resistant steel canopy, providing protection in outdoor and semi‑industrial environments. Thanks to its R96/EUIIIa‑equivalent emissions strategy, it is optimized for fuel efficiency and lower particulate and NOx emissions, meeting current on‑site and mobile‑plant regulations.

Key benefits include low‑noise operation for populated areas, easy service access, and compatibility with standard Cat controllers and remote‑monitoring options, allowing for straightforward maintenance and integration into existing power‑management systems.
