Cat G3520 Fast Response Natural Gas Generator Set — 2,000–3,120 ekW Standby
Caterpillar G3520 Fast Response natural-gas generator set for sale — a standby-rated gas set of 2,000–3,120 ekW that accepts load in seconds, as a gas alternative to diesel backup.
Caterpillar G3520 Fast Response natural-gas generator set available through Pantheon. Cat rates it for standby duty: at 60 Hz it runs 1,800 rpm and is rated 2,000, 2,500 or 3,120 ekW standby at 0.8 power factor, with the 2,500 ekW set ready to accept load in about 7 seconds and the 3,120 ekW set in about 8 seconds. At 50 Hz it runs 1,500 rpm with 2,600 and 3,120 ekW limited-time ratings. These are standby and limited-time ratings, not continuous ones, so they should not be compared directly with the G3520H or G3520K. The sets are EPA certified, with engine-out NOx selectable from 0.5 to 1.0 g/bhp-hr, generator voltages from 440 V to 13.8 kV, and up to 5% hydrogen in the fuel. Exact rating and configuration confirmed at quote.
