What engine does the Generac SDMD2750 use?

The SDMD2750 uses a Baudouin 16M55 87.5-liter V16 turbocharged and aftercooled diesel engine running at 1800 RPM. The Baudouin M55 platform features a bore of 7.08 inches (180 mm), stroke of 8.46 inches (215 mm), and high-pressure common rail fuel injection. This is the same engine platform used in the SD3000/MD3000 and SD3250/MD3250, rated here at 2750 kW. The engine is EPA Certified for Stationary Emergency applications.

What is the fuel consumption of the Generac SDMD2750?

At standby rating on ultra-low-sulfur diesel, the SDMD2750 consumes approximately 192.5 gallons per hour at 100% load, 148 gph at 75% load, and 107 gph at 50% load. At 75% load, a 48-hour runtime requires over 7,100 gallons of fuel, demanding substantial bulk fuel storage and reliable supply logistics.

What voltages are available for the SDMD2750?

The SDMD2750 is available in two three-phase configurations: 277/480 VAC (approximately 4,140 amps) and 346/600 VAC, both at 0.8 power factor. The standard alternator is a Marathon DataMAX unit purpose-built for data center applications with low reactance for superior motor starting performance.

Overview#

The Generac SD2750/MD2750 is a 2,750-kilowatt industrial diesel generator powered by a Baudouin 16M55 87.5-liter V16 turbocharged and aftercooled diesel engine. This unit is EPA Certified for Stationary Emergency applications and is part of Generac's newest generation of large-frame diesel generators designed specifically for hyperscale data center and mission-critical applications. The SDMD2750 uses the same Baudouin V16 engine platform as the SD3000 and SD3250, with bore and stroke dimensions of 180 mm x 215 mm identical across the range.

Generac pairs the Baudouin engine with a Marathon DataMAX alternator purpose-built for data center applications, emphasizing reliability and low reactance. The Deep Sea Electronics G8601 controller provides comprehensive generator management with advanced PLC functionality, SNMP integration, and IP65-rated display. A redundant starting system with isolated battery banks is available to eliminate single points of failure.

Our Service Experience#

The SDMD2750 is a major infrastructure installation typically specified for hyperscale data centers and large campus microgrids. The Baudouin 87.5L V16 platform shares the same cylinder architecture (bore, stroke, piston, liner) as the SD3000 and SD3250, which means common spare parts and service procedures across the lineup. The high-pressure common rail injection system requires ultra-clean fuel, and we strongly recommend duplex fuel-water separators and regular fuel quality testing for standby applications. The dual-circuit coolant system (high-temperature and low-temperature loops) adds complexity compared to single-circuit designs but provides better thermal management at this power level.
