Overview#
The Hipower HRNG-165 is a 131 kW trailer-mounted natural gas generator in Hipower's HRNG mobile series. At 131 kW, the HRNG-165 covers mid-commercial temporary power needs: full essential systems in a commercial building during bypass work, event power at a venue with gas infrastructure, or supplemental power at a construction site with active gas service.
The HRNG series' defining characteristic is its gas supply model: the unit connects to the site's permanent natural gas line rather than carrying on-board diesel. This eliminates fuel delivery, spill risk, and SPCC compliance — at the cost of requiring a confirmed, adequately sized gas supply at the deployment location.
CARB certification makes the HRNG-165 suitable for California temporary standby applications without air district variance. For California construction and event markets where diesel regulations are tightening, gas-fueled towable generators offer a compliant alternative.
PSI Engine Platform#
The HRNG-165 is powered by a PSI natural gas engine running at 1800 RPM. PSI supplies spark-ignited engines to multiple standby generator manufacturers and maintains a broad parts and service network across North America. The specific PSI model for this output class is pending verification from OEM documentation. The spark-ignited platform requires no DPF, no DEF, and no diesel fuel management at the deployment site.
Trailer-Mounted Design#
HRNG units are built on road-legal trailers with tail lights, reflectors, and lockable enclosures. The HRNG-165's trailer allows deployment and relocation between job sites with standard tow vehicles.
CARB-Certified for California#
Hipower's HRNG series holds CARB certification for California temporary natural gas standby. The HRNG-165 qualifies for permit-by-rule in California air districts.
