Overview#

The Kohler KD2000 is a 2000-kilowatt diesel industrial standby generator from Kohler's KD Series platform. At over 2.0 MW, it serves multi-megawatt data center campuses, large hospital systems, and heavy industrial facilities. The KD2000 and larger KD models feature sound aluminum enclosures rated for 186 mph wind loads. The KD Series uses Kohler-designed engines and permanent-magnet pilot exciter alternators.

KD Series platform#

The KD Series is Kohler's large industrial diesel generator line, covering 800 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. The larger KD models (2000 kW and above) use sound aluminum enclosures with 186 mph wind load ratings.

Our service experience#

Estimate runtime on this tank

Estimated runtime

1.7 hours(0.1 days)

Fuel consumption ≈ 115.02 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.
