Overview#
The Blue Star PD600-01 is a 600-kilowatt EPA Tier 2 diesel standby generator powered by the Perkins 2806C-E18TAG3 — an 18.1-liter, six-cylinder turbocharged and charge-air-cooled engine. The PD600-01 marks the transition to Perkins' largest six-cylinder generator platform in this lineup, stepping from the 2506C (15.2L) used in the PD500 and PD550 to the 2806C-E18 (18.1L). Despite the platform change, the 150×78 in base footprint is maintained, though the OPU enclosure grows to 103 inches tall.
Blue Star Power Systems (North Mankato, Minnesota) pairs the 2806C-E18TAG3 with a Stamford HCI534E alternator — the same alternator model as the PD550-01 at 480V — and DSE DCP7310 controller. At 10,625 lbs, the PD600-01 is 750 lbs heavier than the PD550-01. The altitude deration improves to 3,281 ft (1,000 m) at 86°F (30°C), recovering from the PD550's restrictive 1,640 ft limit. The heat radiated to ambient (714,120 BTU/hr) exceeds the coolant heat rejection (627,420 BTU/hr) — an unusual thermal profile that warrants careful equipment room heat management planning.
Platform Change: The 2806C-E18 at 600 kW#
The 2806C-E18 displaces 18.1 liters from the same six-cylinder architecture as the 2506C, with a longer stroke and larger bore. At the TAG3 calibration, it produces 600 kWe standby with a significantly lower specific output than the ceiling-stressed 2506C-E15TAG4 — which is reflected in the improved altitude deration. The exhaust temperature (1,029°F) is lower than the 1,256°F seen on the 2206D-E13 models, and the combustion air requirement (1,837 CFM) is higher, consistent with the larger displacement.
When to spec the PD600-01#
- 575–600 kW three-phase emergency standby loads on diesel fuel at moderate-elevation sites
- Projects requiring 600 kW output with improved altitude headroom compared to the PD550
- Facilities where the 150×78 in footprint is established from prior models (no footprint change from PD450–PD550)
- Healthcare, data center, industrial, and municipal applications requiring the 600 kW tier with Tier 2 compliance
Our service experience#
The 2806C-E18TAG3 introduces a new engine platform with different service parts than the 2506C series. Confirm parts inventory and service documentation coverage at commissioning. The unusually high heat-radiated-to-ambient value (714,120 BTU/hr vs 627,420 BTU/hr coolant rejection) means the equipment room will experience more radiant heat than at similar output levels — verify HVAC load calculations account for this. The HCI534E alternator is shared with the PD550-01, simplifying service across both models. Follow the Perkins 2800C generator series maintenance schedule.
