Product Overview
The BetaSet / BetaGen 25/2 is a compact, Kubota‑based diesel generator engineered for marine use. With continuous outputs ranging from 14.8–31 kVA depending on operating voltage and frequency, and fixed speeds of 3000 rpm (50 Hz) or 3600 rpm (60 Hz), it delivers reliable power up to 31 kVA in a compact footprint. Supplied with heat exchanger, keel cooling, or radiator options, it’s optimized for craft under 20 m or 100 m³, meeting CCNR Stage IIIA emission standards for inland waterways.
Key Features
- Versatile Output & Speed: 14.8–31 kVA @ 3000 rpm (50 Hz) or 3600 rpm (60 Hz)
- Choice of Cooling Systems: Heat exchanger, keel, or radiator cooling to suit vessel needs
