2500REOZDB Industrial – Kohler® Diesel Generator


  • 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 generator set accepts rated load in one step.
  • 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-, five-, and ten-year extended warranties are also available.

Alternator Features:

  • The pilot-excited, permanent-magnet (PM) alternator provides superior short-circuit capability.
  • The brushless, rotating-field alternator has broad range reconnectability.
  • Additional alternator voltages are available including 12.47 kV, 13.2 kV, and 13.8 kV medium voltages. Contact your local distributor for details.
  • 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.
  • Superior voltage waveform from a two-thirds pitch stator and skewed rotor.
  • Digital solid-state, volts-per-hertz voltage regulator with ±0.25% no-load to full-load regulation.
  • Brushless alternator with brushless pilot exciter for excellent load response.

Other Features:

  • Kohler designed controllers for guaranteed system integration and remote communication.
  • The low coolant level shutdown prevents overheating (standard on radiator models only).
  • An electronic, isochronous governor delivers precise frequency regulation.
  • Multiple circuit breaker configurations.
