What engine does the PD20-01IT4 use?

The Perkins 404D-22G — a 2.22-liter, four-cylinder naturally aspirated diesel rated for this 17 kWe standby application. The 404D-22G is a mechanically simple engine without turbocharging, which contributes to its reliability and ease of service in light-duty standby applications. It is EPA Tier 4 Interim certified for stationary emergency use.

What controller does the PD20-01IT4 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. It is cULus Listed and CE Approved with IP 65 ingress protection (with supplied gasket).

How does the PD20-01IT4 compare to the PD30-01IT4?

Both models share the same 2.22-liter Perkins 404D platform. The PD20-01IT4 uses the naturally aspirated 404D-22G rated at 17 kWe on a 66×36 in footprint at 1,275 lbs. The PD30-01IT4 steps up to the turbocharged and charge-air-cooled 404D-22TAG, producing 25 kWe on a slightly larger 80×38 in skid at 1,600 lbs. Full-load fuel consumption: 1.81 gph (PD20) vs 2.59 gph (PD30).

What are the ventilation requirements for an indoor PD20-01IT4 installation?

The PD20-01IT4 requires 1,654 CFM of radiator cooling airflow for the standard unit-mounted radiator configuration. Combustion air requirement is 62 CFM. Heat radiated to ambient is 16,500 BTU/hr; the coolant circuit rejects 76,140 BTU/hr through the unit-mounted radiator. Rated power is available up to 1,640 ft elevation at ambient temperatures to 86°F (30°C).

Overview#

The Blue Star PD20-01IT4 is a 17-kilowatt Tier 4 Interim diesel standby generator built around the Perkins 404D-22G, a 2.22-liter naturally aspirated four-cylinder engine. It is the smallest model in Blue Star's Perkins diesel lineup, suited for light-commercial and small-facility standby applications where a compact, quiet footprint matters.

Blue Star Power Systems (North Mankato, Minnesota) pairs the 404D-22G with a Stamford S1L2-J41 alternator and DSE DCP7310 controller. At 66×36 in and 1,275 lbs, the PD20-01IT4 is one of the most compact radiator-cooled standby generators in the Blue Star lineup and is rated for a sound level of 72 dBA at 7 meters — the lowest in the Perkins diesel series.

The 404D-22G at 17 kWe#

The Perkins 404D-22G is a naturally aspirated engine, meaning it has no turbocharger or intercooler. This simplifies the drivetrain, reduces maintenance touchpoints, and makes the engine highly reliable for infrequent-start standby duty cycles. The 2.22-liter displacement is sufficient for 17 kWe at 1800 RPM, and fuel consumption is modest at 1.81 gph at full load.

When to spec the PD20-01IT4#

15–17 kW emergency standby loads on diesel fuel
Small commercial offices, retail units, worship facilities, and telecom enclosures
Sites where Tier 4 Interim certification is required
Locations where the compact 66×36 in footprint and low 72 dBA noise level are decision criteria

Our service experience#

The naturally aspirated 404D-22G requires fewer service touchpoints than turbocharged engines of similar displacement. There is no intercooler hose system or boost pressure to monitor. We recommend load bank testing at commissioning and standard Perkins 404D industrial service intervals. Parts are available through the Perkins dealer network.
