Overview#

The Kohler KD700 is a 700-kilowatt diesel industrial standby generator from Kohler's KD Series platform. Powered by the Kohler KD18L06 — a 17.96-litre six-cylinder inline diesel engine rated at 1053 BHP — the KD700 serves data centers, healthcare facilities, and commercial buildings requiring reliable large-scale backup power. The engine is compatible with HVO (hydrotreated vegetable oil) renewable diesel. The KD Series uses Kohler-designed engines and permanent-magnet pilot exciter alternators for sub-3% total harmonic distortion.

KD Series platform#

The KD Series is Kohler's large industrial diesel generator line, covering 700 to 4000 kW. Designed for mission-critical facilities, every KD Series unit carries UL 2200 listing and meets NFPA 110 Level 1 requirements when equipped with the necessary accessories. Hurricane-rated enclosures with 186 mph wind load ratings are available across the platform.

Our service experience#

OnPoint Generators provides installation, maintenance, and emergency service for Kohler KD Series generators throughout Northern California. Our technicians are experienced with large diesel platforms in the megawatt class, including load bank testing, fuel system maintenance, and cooling system service for high-capacity industrial units.

Fuel consumption ≈ 37.11 GPH at 75% load. Estimate based on industry-typical 1800 RPM standby curves (≈0.07 GPH/kW at full load). Actual consumption varies by engine, ambient temperature, fuel quality, and tuning.

Service intervals

Manufacturer-recommended intervals for the Kohler KD700 under standby duty. Field intervals may differ based on load profile, ambient conditions, and fuel quality.

Oil & filter: Every 500 hours or 12 months
Coolant change: Every 6000 hours
Air filter: Every 1000 hours
Fuel filter: Every 500 hours
Major overhaul: ≈ 20,000 hours
Load bank test: Every 12 months

Common failure modes
