Top Features

  • 227 kVA Prime Output

  • Flexible, Reliable, Environmentally Sensitive Power Source

 

The HRNG 230 LPG generator set is powered by a radiator-cooled, industrial PSI-HD gaseous engine, which meets current Environmental Protection Agency (EPA) non-road exhaust emission regulations, driving a single bearing, four-pole, three-phase alternator, with IP23 protection. The Prime Power kVA rating for the HRNG 230 generator set is given with a 125 degree C alternator winding temperature rise.
