Gas generator sets
DG450 Compact (3-Phase)
The Cat® spark-ignited rich burn gas generator set can be used for emergency standby, prime, demand response and limited time power (LTP) applications. It also offers a reliable power with superior fuel efficiency, lower footprint and cleaner exhausts with ultra-low-NOx capability. With dual fuel kit option, automatic transition to propane from natural gas delivers uninterrupted operation. This also comes with an optional paralleling configuration up to 4 units in conjunction with a switchgear built on a Distributed Energy Resources (DERs) technology platform. The DERs technology continuously monitors, analyses and controls multiple energy sources.
