  • Engine shut down protection for overheat and low oil pressure.
  • Entire inside of the covers insulated with special material designed to reduce the noise extremely.
  • Temperature controlled engine cooling fan exchanges air in APU only when required to reduce noise, power consumption and increases heat quickly for optimum efficiency of engine.
  • Provides more heat quicker than any other system on the market.
  • Multi chamber exhaust specially designed to reduce noise.
  • Automatic reset breakers for 110vac built into unit - no getting out to reset.
  • Newage double bearing generator with replaceable components.
