Product Overview
The BetaSet / BetaGen 22/2 is a compact, marine-grade generator set delivering up to 23 kVA. Built around a 4‑cylinder Kubota-based engine with either 3000 rpm (50 Hz) or 3600 rpm (60 Hz) operation, it’s available with heat exchanger, keel, or radiator cooling. This model is ideal for vessels under 20 m or 100 m³ and meets CCNR Stage IIIA emission requirements.
Key Features
- Max Output: 11.1–23 kVA depending on voltage and frequency
- Versatile Operation: 230 V 1ph or 400 V 3ph @ 50 Hz | 120/240 V 1ph or 440 V 3ph @ 60 Hz
- Kubota-Based Engine: 4‑cylinder, 1,498 cc diesel, naturally aspirated and mechanically governed
- Cooling Options: Heat exchanger, keel, or radiator cooling for flexible installation
- Low Fuel Consumption: Only 4.5–4.8 litres/hour depending on operating frequency
- CCNR Compliant: Suitable for commercial & recreational craft under 20 m (except Lake Constance)
