The Gillette SPHD-9000 is a 900-kilowatt stationary diesel standby generator on Hyundai's DP222CCS V12 — the only Hyundai-powered model in Gillette's diesel lineup. At 21.9L displacement producing 900 kW (1,334 bhp), the Hyundai DP222 achieves remarkably high power density compared to the Mitsubishi S-series. Stamford S6DD311 alternator with shunt excitation, DSE 7420 MKII controller.
The SPHD-9000 fills a unique 900 kW output point between the SPMI-8000 (800 kW Mitsubishi) and SPMI-1M (1,000 kW Mitsubishi), offering a lighter and more compact alternative at a specific output tier.
The most notable characteristic of the SPHD-9000 is its power density:

The Hyundai V12 delivers 100 kW more output from 35% less displacement at half the weight. The tradeoff: higher specific loading per liter means the engine operates at higher thermal and mechanical stress.
The SPHD-9000 differs from the SPMI series in several certification areas:
No UL 2200 — carries UL 1446 and UL 508, but not the UL 2200 generator set listing that many commercial specs mandate
Shunt excitation (not PMG) — the Stamford S6DD311 uses conventional shunt excitation, which may have slower voltage recovery under severe transients compared to PMG
ASCE 7-05 at 180 MPH — the older wind load standard vs. ASCE 7-22 at 200 MPH on the SPMI series
For projects requiring UL 2200, PMG excitation, or current wind load certification, the SPMI-8000 or SPMI-1M are the appropriate alternatives despite the weight penalty.
The Hyundai DP222 is less common in our territory than Mitsubishi S-series or Caterpillar 3500 series engines at this power class. Hyundai's parts availability in North America is growing but not as established as Mitsubishi's network. For clients considering the SPHD-9000, we recommend confirming local parts availability and stocking critical spares on-site (filters, belts, turbocharger components) to ensure rapid response during service events.

Frequently Asked Questions
What engine does the SPHD-9000 use?
Hyundai DP222CCS — a 21.9L turbocharged and water-to-air aftercooled V12 diesel producing 1,334 bhp at standby. Hyundai's industrial diesel engines are less common in the North American generator market than Mitsubishi, but the DP222 is a well-proven platform used in power generation globally.
How does the SPHD-9000 compare to the SPMI-8000?
The SPHD-9000 (900 kW, Hyundai 21.9L V12, 9,764 lbs) is significantly lighter than the SPMI-8000 (800 kW, Mitsubishi 33.9L V12, 18,950 lbs) — nearly half the weight for 100 kW more output. The Hyundai achieves this with higher power density from less displacement. However, the SPHD-9000 uses shunt excitation (not PMG), has UL 1446 but NOT UL 2200, and has the older ASCE 7-05 wind rating at 180 MPH vs 200 MPH on the SPMI series.
Why doesn't the SPHD-9000 have UL 2200?
The SPHD-9000 carries UL 1446 and UL 508 but not UL 2200. For applications requiring UL 2200 listed equipment (many commercial and institutional specifications mandate it), the SPMI-8000 or SPMI-1M are the appropriate alternatives. Verify your project's UL listing requirements before specifying.
What are the voltage options?
480V and 600V three-phase only — the same limitation as the SPMI-1.5M and SPMI-2M. At 900 kW, lower voltages produce impractical current levels.
