600 kW standby / 570 kW prime Tier 4 Final diesel generator from Blue Star Power Systems. Volvo Penta TWD1683GE 16.12L inline-six with SCR/DPF/DOC, DSE DCP7310 controller, three-phase 208-600V.
The Blue Star VD600-04FT4 is a 600-kilowatt standby / 570-kilowatt prime EPA Tier 4 Final / EU Stage 5 diesel generator — the highest-output model in the Blue Star Tier 4 Final lineup. It is built around the Volvo Penta TWD1683GE, a 16.12-liter inline-six with water-cooled charge-air cooling rated 932 HP at 1800 RPM. This is a current-production active model.
The VD600-04FT4 shares its footprint and basic architecture with the VD550-04FT4, with key distinctions: structural steel base frame (vs formed steel), voltage-dependent alternator selection, and a 5,000W 240V jacket water heater (the largest in the T4F lineup).
The TWD1683GE shares its service platform with the TWD1682GE (VD550): same engine family, similar fluid capacities and filter cross-references, with the primary differences being output calibration and the structural steel base requiring different lifting and mounting procedures. The 5,000W jacket water heater requires 240V facility power for cold-weather standby readiness — verify the electrical supply plan during site design. The voltage-dependent alternator selection (HCI534F vs S6L1D-C) must be confirmed at order time; alternator changes post-delivery are impractical. The 40.0 in H2O maximum exhaust back-pressure post-catalyst is the tightest restriction in the T4F lineup — verify the exhaust system design early in the project.#

Frequently Asked Questions
What engine is in the VD600-04FT4?
The Volvo Penta TWD1683GE — a 16.12-liter inline-six turbocharged diesel with water-cooled charge-air cooler (H2O-to-Air CAC), rated 932 HP (695 kWm) at 1800 RPM. It is the higher-output variant of the TWD1682GE used in the VD550-04FT4, sharing the same 16.12L displacement. EPA Tier 4 Final and EU Stage 5 certified with SCR/DPF/DOC triple aftertreatment.
What alternator does the VD600-04FT4 use?
The alternator selection is voltage-dependent. The Stamford HCI534F is used for 480V and 600V configurations. The Stamford S6L1D-C is used for 120/208V three-phase configurations. Both provide ±0.50% voltage regulation. Confirm the required alternator with Blue Star at order time based on the site voltage requirement.
Does the VD600-04FT4 require DEF?
Yes. DEF consumption is approximately 6.00% of fuel consumption. The 52.8-gallon integrated DEF tank provides extended runtime — at full standby load (39.6 gph fuel), DEF consumption is approximately 2.38 gph, giving approximately 22 hours of full-load operation before DEF refill.
How does the VD600-04FT4 differ from the VD550-04FT4?
Both use the same 16.12L Volvo Penta TWD platform and share the same 160 x 84 x 118 in footprint. The TWD1683GE (VD600) is the higher-output variant producing 600 kWe standby / 570 kWe prime versus 550/500 for the VD550's TWD1682GE. The VD600 is 325 lbs heavier (13,425 vs 13,100 lbs), uses a structural steel base frame (vs formed steel on the VD550), and requires a voltage-dependent alternator selection between HCI534F and S6L1D-C.
What is the exhaust restriction specification for the VD600-04FT4?
The maximum allowable exhaust back-pressure post-catalyst is 40.0 in H2O. This is a critical installation parameter — exceeding this restriction affects engine performance and aftertreatment function. Verify exhaust system design against this limit before finalizing the installation.
