Bergen C25:33 generating set
Proven low life-cycle cost for operators.
Reliable power in a compact design
The Rolls-Royce Bergen C-series engine and gensets have a simple and robust design with a reduced number of components. Introduced at 300kW/cyl., it is now rated at 330kW/cyl. and is equally suitable for main propulsion, either with mechanical transmission or in a diesel electric system, or as a marine generating set.
With 6, 8 and 9 cylinders in-line, the C-series has a range of operating speeds from 720rpm to 1,000rpm and can be supplied for powers of 1,920 to 3,000kW.
- Extremely stable electrical frequency, important for frequency sensitive equipment
- Low vibration/structural noise level due to super-resilient mounting
- Certified to meet IMO Tier II requirements
- Competitive fuel and lubricating oil consumption
- No fuel oil leakage into the lubricating oil system due to the Bergen Cofferdam system
- Single-bearing alternator option for reduced genset length, and reduced cost, through elimination of flexible
- Coupling between engine and alternator
- High power to weight ratio
- The liner, piston, (incl. upper con rod) and cylinder head can be replaced as a single unit without disturbing the big end bearing, saving time and money
