The PR series is prime-rated gas power — 80 kW to 540 kW on natural gas, engineered for the conditions of remote oil and gas operations where the generator is the power source rather than the backup. PSI prime movers drive Stamford generator ends, the pairing Gillette uses across its prime lineup.
Features and benefits
- Built for continuous duty. Prime rating means sustained running and repeated load cycling, not occasional exercise and the rare outage.
- PSI prime movers. Gas engines selected for prime service rather than a standby engine pressed into continuous duty.
- Stamford generator ends. The alternator brand most commonly specified on industrial sets, and widely supported for parts and service.
- Wellhead and remote site duty. Engineered for the difficult conditions of remote oil and gas operations, including demand response work.
- Runs on field gas or pipeline gas. Useful where fuel is available on site and hauling diesel is the expensive part.
- Seven models, 80-540 kW. Sized to the site rather than the catalog.
Prime rated. Unlike a standby set, this one is built to run as the site's regular power source, for long hours and repeated duty cycles. That means heavier-duty engine selection and cooling than a comparable standby machine.
About Gillette
Gillette has been building industrial generator systems in Elkhart, Indiana for more than 60 years, from 25 kW to 2 MW. Every set is UL 2200 certified and 100% load tested before it ships, and the company holds a 99% on-time delivery record — which matters when a set is tied to a construction schedule or a code-required inspection date.
