What engine does the PD400-01 use?

The Perkins 2206D-E13TAG3 — a 12.5-liter, six-cylinder turbocharged and charge-air-cooled diesel. The TAG3 calibration of the 2206D-E13 platform produces 400 kWe standby, 50 kWe above the TAG2 calibration (PD350-01) on the same engine architecture and footprint. It carries EPA Tier 3 certification for stationary emergency applications. Rated power is available up to 3,281 ft (1,000 m) at ambient temperatures to 104°F (40°C).

What controller does the PD400-01 use?

The DSE DCP7310 Digital Control Panel, with CAN Bus J1939 engine communication, digital metering, RS-485 interface, 8 programmable contact inputs, 10 contact outputs, and NFPA 110 Level 1 compatibility. The panel is cULus Listed and CE Approved with IP 65 ingress protection (with supplied gasket). A 24V battery system and 24V 5 Amp battery charger are standard.

How does the PD400-01 compare to the PD350-01 and PD450-01?

The PD350-01 (TAG2) and PD400-01 (TAG3) share the same 2206D-E13 engine platform and identical 140×72 in footprint — 300 lbs separate them (7,875 vs 8,175 lbs). Both produce exhaust at 1,256°F and require 27,845 CFM ventilation airflow. The PD450-01 steps to the larger 2506D-E15 platform (15.2L) on a 150×78 in footprint, structural steel base, and Stamford HCI534C alternator — a full platform change with a meaningfully larger footprint.

What are the ventilation and thermal requirements for the PD400-01?

The PD400-01 requires 27,845 CFM of radiator cooling airflow — the same as the PD350-01, since both use the same 2206D-E13 engine and radiator configuration. Combustion air draw is 1,053 CFM. Heat rejected to the coolant circuit is 534,180 BTU/hr; heat radiated to ambient is 484,140 BTU/hr. Exhaust exits at 1,256°F at 3,046 CFM — verify exhaust component ratings. For fuel planning: at full load (26.8 gph), a 1,000-gallon tank provides approximately 37 hours of runtime.

Overview#

The Blue Star PD400-01 is a 400-kilowatt Tier 3 diesel standby generator powered by the Perkins 2206D-E13TAG3 — the higher-output calibration of the 12.5-liter, six-cylinder turbocharged and charge-air-cooled platform. The PD400-01 shares its 140×72 in footprint with the PD350-01, differing in engine calibration (TAG3 vs TAG2), alternator (S4L1D-F41 vs S4L1D-E41), and an additional 300 lbs — making it the highest-output model on the 2206D-E13 platform in Blue Star's lineup.

Blue Star Power Systems (North Mankato, Minnesota) pairs the 2206D-E13TAG3 with a Stamford S4L1D-F41 alternator and DSE DCP7310 controller. At 8,175 lbs, the PD400-01 is the heaviest model in the 140×72 in footprint class. Sound level steps up to 91 dBA at full load. Deration: rated power is available to 3,281 ft (1,000 m) at 104°F (40°C).

The 2206D-E13 at Its Ceiling#

The TAG3 calibration represents the peak output of the 2206D-E13 generator engine family in Blue Star's lineup. At 400 kWe standby, the engine produces 26.8 gph at full load — 11.7% more than the TAG2 at 350 kWe. Ventilation requirements are identical between the PD350 and PD400 (27,845 CFM), and both produce exhaust at 1,256°F, so equipment room infrastructure changes when upgrading from a PD350 are minimal. The PD400 is the last model in Blue Star's lineup with a formed steel base — the PD450 and above use structural steel.

When to spec the PD400-01#

375–400 kW three-phase emergency standby loads at moderate-elevation sites
Facilities where the 140×72 in footprint is established and the PD350 is already installed (same footprint, no room modification)
Commercial, industrial, data center, and municipal applications requiring the 400 kW tier with Tier 3 compliance
The last Blue Star Perkins diesel model before the platform shifts to the 2506D-E15 with structural steel base

Our service experience#

The PD400-01 at 400 kWe is operating at the TAG3 ceiling of the 2206D-E13 platform. Annual full-load load bank testing is strongly recommended. The 1,256°F exhaust temperature is sustained at this output level — inspect exhaust flex connectors, silencer mounting, and heat shielding at every annual service. The ventilation system (27,845 CFM) should be verified during commissioning. Follow the Perkins 2200D generator series maintenance schedule.
