Kohler-Built, Through and Through

A generator consists of two main parts: the engine and the alternator. While most brands outsource their engines, Kohler designs and builds both components in-house. Consequently, this unified approach ensures better quality and superior performance. Ultimately, these units offer the exceptional reliability required for demanding marine use.

Quiet Confidence at 1500 RPM

• Low-Tone Operation: Because this generator runs at a steady 1500 rpm, it produces a deep, even rumble rather than a high-pitched whine.
• Constant Speed Efficiency: Diesel engines perform best under a consistent load, which helps prevent cylinder glazing and extends engine life.
• Ideal for Charging: This fixed-speed model is the perfect partner for systems focused on heavy-duty battery charging.
• Lubricated Health: Regular cycles keep internal parts lubricated, ensuring the system remains healthy for every crew member.

Selecting the Right Size for Your Vessel

Kohler provides various sizes, but for a narrowboat, the 5kW or 7kW models are most effective. Your choice usually depends on the available engine room space and the access required for maintenance.

The 5kW model is 10cm shorter, which makes it significantly easier to service in tight spaces. In contrast, the 7kW model offers more power but requires a larger footprint. Therefore, the 5kW unit is often the most practical choice for a Törkmar energy setup. Although it serves as a backup source rather than primary power, its reliability ensures peace of mind for the whole boat.
