The Gillette PR-2400 is a 240-kilowatt prime-rated natural gas generator on PSI's 14.6L turbocharged V8 — the same engine platform as the SP-3500 standby (350 kW). At 240 kW prime (362 bhp), the engine operates well within its thermal design limits for unlimited continuous duty. Three-phase only, Stamford S4L1DD alternator, DSE 7420 MKII controller.
Standby to prime: the SP-3500 and PR-2400 relationship#
The PSI 14.6L V8 demonstrates the standby-to-prime derating pattern:
PR-2400: 240 kW prime (362 bhp) — unlimited continuous duty
The 31% derating ensures engine longevity under sustained load. For facilities that need continuous power at 200+ kW on natural gas, the PR-2400 is the appropriate specification.
The PSI 14.6L at continuous duty requires 8-cylinder ignition service at 1000-hour intervals — approximately every 6 weeks at 24/7 operation. We structure PR-2400 maintenance as multi-technician service events to complete the 8-cylinder ignition, oil, and air filter service efficiently within a planned maintenance window.

Estimate runtime on this tank
Fuel demand at 75% load
2,520,000 BTU/hr≈ 2520.0 cf/min @ 1,000 BTU/cf
On utility natural gas the runtime is generally unlimited provided the supply line and meter can deliver this BTU/hr at the engine's required inlet pressure (typically 5–14" WC residential, up to 5 psi commercial). Confirm against the OEM's published fuel-pressure spec.

Frequently Asked Questions
Is this the same 14.6L V8 as the SP-3500 standby?
Yes — same PSI 14.6L V8 TCAC engine block. The SP-3500 is rated at 350 kW standby; the PR-2400 is rated at 240 kW prime. The 31% lower prime rating ensures the engine operates within thermal limits for unlimited continuous duty hours.
What fuel consumption at 240 kW prime?
3,086 ft3/hr NG at full load. At 75%: 2,292 ft3/hr. At 50%: 1,610 ft3/hr. At continuous duty, this is a significant sustained gas demand requiring a dedicated commercial gas service.
200 kW natural gas stationary standby generator. Made-in-USA commercial unit with PSI 8.8L high-output turbocharged V8, Stamford alternator, and DSE 7420 MKII controller. NG only.
