  • KOHLER Co. provides one-source responsibility for the generating system and accessories.
  • The generator set and its components are prototype-tested, factory-built, and production-tested.
  • The 60 Hz generator set offers a UL 2200 listing.
  • The 60 Hz generator set meets NFPA 110, Level 1, when equipped with the necessary accessories and installed per NFPA standards.
  • A one-year limited warranty covers all systems and components. Two- and five-year extended warranties are also available.

Alternator features:
  • Kohler's wound field excitation system with it's unique PowerBoost™ design delivers great voltage response and short-circuit capability.
  • The brushless, rotating-field alternator has broad range reconnectability.
  • NEMA MG1, IEEE, and ANSI standards compliance for temperature rise and motor starting.
  • Sustained short-circuit current of up to 300% of the rated current for up to 10 seconds.
  • Sustained short-circuit current enabling down stream circuit breakers to trip without collapsing the alternator field.
  • Self-ventilated and drip-proof construction.
  • Vacuum-impregnated windings with fungus-resistant epoxy varnish for dependability and long life.
  • Superior voltage waveform from a two-thirds pitch stator and skewed rotor.

Engine features:
  • Heavy-duty air cleaner with air restrictor indicator.
  • Uses cooled Exhaust Gas Regeneration (EGR) and diesel oxidation catalyst to meet Tier 4 Final without a Diesel Particulate Filter (DPF).
  • Lockable battery disconnect switch.
  • Electronic isochronous governor.

Other features:
  • Kohler designed controller for guaranteed system integration and remote communication.
  • The low coolant level shutdown prevents overheating (standard on radiator models only).
  • Integral vibration isolation eliminates the need for under-unit vibration spring isolators.
  • Durable steel, sound-attenuating housing with quiet operation of 67 dB(A) @ 7 m (23 ft.) with full load at prime rating.
  • Stainless steel hinges and lockable latches on doors.
