What engine does the PD30-01IT4 use?

The Perkins 404D-22TAG — a 2.22-liter, four-cylinder turbocharged and charge-air-cooled (intercooled) diesel rated for this 25 kWe standby application. The TAG designation indicates turbocharging plus charge air cooling, extracting more power from the same 2.22-liter block used in the naturally aspirated PD20-01IT4. It is EPA Tier 4 Interim certified for stationary emergency use. Rated power is available up to 6,562 ft elevation at ambient temperatures to 104°F (40°C).

What controller does the PD30-01IT4 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 PD30-01IT4 compare to the PD20-01IT4 and PD50-01?

All three are compact Perkins-powered standby generators. The PD20-01IT4 uses a naturally aspirated 404D-22G (17 kWe, 66×36 in, 1,275 lbs). The PD30-01IT4 steps up to the turbocharged and intercooled 404D-22TAG (25 kWe, 80×38 in, 1,600 lbs). The PD50-01 moves to the larger 4.4-liter 1104D-44TG1 platform (50 kWe, 80×38 in, 2,225 lbs) at Tier 3. Full-load fuel: 1.81 / 2.59 / 4.42 gph respectively.

What are the ventilation and altitude considerations for the PD30-01IT4?

The PD30-01IT4 requires 2,544 CFM of radiator cooling airflow and 88 CFM combustion air. Heat radiated to ambient is 37,260 BTU/hr; the coolant circuit rejects 129,240 BTU/hr. Exhaust exits at 892°F at 297 CFM. The 404D-22TAG has an excellent altitude rating — rated power is available up to 6,562 ft (2,000 m) at ambient temperatures to 104°F (40°C), making it suitable for high-elevation installations.

Overview#

The Blue Star PD30-01IT4 is a 25-kilowatt Tier 4 Interim diesel standby generator powered by the Perkins 404D-22TAG, a 2.22-liter turbocharged and charge-air-cooled four-cylinder engine. It sits between the naturally aspirated PD20-01IT4 and the 4.4-liter PD50-01, occupying a size class well suited for small commercial and municipal standby loads.

Blue Star Power Systems (North Mankato, Minnesota) pairs the 404D-22TAG with a Stamford S1L2-J41 alternator and DSE DCP7310 controller on a compact 80×38 in skid weighing 1,600 lbs. The 404D-22TAG's excellent altitude capability — rated to 6,562 ft (2,000 m) at 104°F — gives the PD30-01IT4 a meaningful advantage over competing models in mountain and high-elevation installations.

The 404D-22TAG at 25 kWe#

The turbocharged and intercooled 404D-22TAG extracts 25 kWe from the same 2.22-liter block used in the PD20-01IT4's naturally aspirated 404D-22G. The charge air cooling (intercooler) reduces intake charge temperature, allowing denser air/fuel mixtures and better efficiency at altitude. Exhaust temperature at stack is 892°F — moderate for a diesel of this size, which keeps exhaust system requirements straightforward.

When to spec the PD30-01IT4#

20–25 kW emergency standby loads on diesel fuel
Small commercial, telecom, worship, and municipal applications
High-elevation sites where altitude derating would eliminate competing models
Tier 4 Interim required by local air quality regulations

Our service experience#

The 404D-22TAG is a well-proven Perkins engine used broadly in light industrial and generator applications. Service intervals follow the standard Perkins 400D generator series schedule. Parts are available through the Perkins dealer network. Load bank test at commissioning to verify full-load pickup under site conditions, particularly at higher elevations.
