Blue Star PD200-01

Overview#

The Blue Star PD200-01 is a 200-kilowatt Tier 3 diesel standby generator powered by the Perkins 1106D-E70TAG5, the highest-output calibration of the 7.01-liter six-cylinder platform in Blue Star's lineup. The TAG5 engine delivers 200 kWe from the same 110×54 in footprint shared with the PD125-01 through PD180-01 — enabling four power levels from 125 to 200 kW without a change in equipment room size.

Blue Star Power Systems (North Mankato, Minnesota) pairs the 1106D-E70TAG5 with a Stamford UCI274H alternator and DSE DCP7310 controller. At 4,150 lbs, the PD200-01 is 225 lbs heavier than the PD180-01, with the difference primarily in the larger UCI274H alternator frame. The radiator cooling airflow requirement steps up substantially to 10,161 CFM — verify adequate louver and ventilation sizing when upgrading from a PD180-01 in an existing equipment room.

The 1106D-E70TAG5 at Its Ceiling#

The TAG5 represents the peak output calibration of the 1106D-E70 generator engine family. At 200 kWe standby, the engine is running at its rated maximum — reflected in the tighter altitude/temperature deration (1,640 ft / 122°F vs 3,281 ft / 104°F for the TAG4). The exhaust temperature climbs to 1,027°F and ventilation airflow jumps to 10,161 CFM. These are the most demanding thermal conditions in the Perkins PD series. Both the altitude restriction and the elevated thermal load make the PD200-01 more site-sensitive than lower-output models.

When to spec the PD200-01#

• 175–200 kW emergency standby loads on diesel fuel at lower-elevation, moderate-temperature sites
• Commercial, light-industrial, and multi-family applications where 200 kW fits the 110×54 in footprint
• Sites upgrading from a 150–180 kW PD model without equipment room expansion
• Competitive bids where Tier 3 compliance is acceptable and the 200 kW output tier is required

Our service experience#

The 1106D-E70TAG5 at 200 kWe is operating at its peak rated output. Load bank testing at commissioning is essential, and annual full-load verification is strongly recommended. The elevated exhaust temperature (1,027°F) requires careful attention to exhaust system component ratings and vibration isolation. Inspect the intercooler and charge air piping annually. For sites at or near the altitude/temperature limits, consider specifying the next-size-up model to maintain adequate deration margin. Follow the Perkins 1100D generator series service schedule; the TAG5 calibration warrants adhering strictly to oil change intervals.
