200 kW Tier 4 Final / Stage 5 diesel generator with Volvo Penta TAD1180VE 10.8L engine. SCR aftertreatment, DEF, Basler DGC-2020 controller. Made in USA.
The Gillette T4D-2000 is a 200-kilowatt Tier 4 Final / EU Stage V dual-certified diesel generator on Volvo's TAD1180VE — a 10.8L turbocharged inline-6 with SCR aftertreatment. Rated at 200 kW for both standby and prime. Stamford HCI434D alternator, Basler DGC-2020 controller.
The TAD1180VE's 10.8L displacement is unique to the T4D Tier 4 Final lineup. It demonstrates how Tier 4 Final engine engineering differs from Tier III: more displacement (10.8L vs. 7.0L Perkins) for the same kW output, running at lower specific loading with better fuel efficiency. The result: 11.6 gal/hr vs. 15.6 gal/hr for the Tier III SPD-2000 at the same 200 kW.
The Volvo TAD1180VE at 200 kW is well within its design envelope. We add DEF system checks to every service visit — DEF quality testing, tank level verification, and SCR catalyst performance monitoring.

Frequently Asked Questions
What engine does the T4D-2000 use?
Volvo Penta TAD1180VE — a 10.8L turbocharged inline-6. This is a displacement unique to the Tier 4 Final lineup (the Tier III SPVD series doesn't use a 10.8L). 320 bhp at standby, 16.9:1 compression. DEF consumption approximately 5.3% of diesel.
How does the T4D-2000 fuel efficiency compare to the Tier III SPD-2000?
The T4D-2000 consumes 11.6 gal/hr at 200 kW vs. the SPD-2000 at 15.6 gal/hr at 200 kW. The Tier 4 Final Volvo engine is significantly more fuel-efficient than the Tier III Perkins — a meaningful operating cost advantage that partially offsets the higher initial cost and DEF expense.
