The units are powered by the high-efficiency KD83V16 engine, which has been optimized through modifications to the engine control unit software. This innovative approach has resulted in best-in-class power density and NOx emissions in a compact footprint.
Design features include a rigid chassis that integrates a mechanically driven fan, in line with a global design strategy for key markets, including EMEA and the United States. Cooling with a mechanical fan instead of an electric one eliminates the need for a motor and step-down transformer, reducing the size, weight, and complexity of the components.
The KD3750 is offered in two variants—the KD3750-F and the KD3750-E—with design temperatures of 50 and 40 degrees Celsius, respectively. These options provide end users with fuel- and emissions-optimized configurations to meet the requirements of their local markets.
The best-in-class power density is 150kVA/m², while NOx emissions are <2000mg/Nm3@5%O2 up to prime power.
The KD3750 is suitable for use with conventional diesel and renewable fuels, including hydrogen-treated vegetable oil (HVO). HVO, approved according to EN15940, is derived entirely from waste products and is up to 90% carbon neutral. It can be mixed directly in the generator's tanks with conventional diesel without any issues.
“The launch of the KD3750 generator series further strengthens our product range for mission-critical applications,” says Pierre Adrien Bel, Product Manager for Large Generators at Kohler Power Systems EMEA. “The units are highly optimized and customizable, delivering excellent power density in a compact design. And with HVO compatibility, the KD3750 also significantly advances sustainability for mission-critical applications such as data centers.”
