DG450 Compact (3-Phase)

DG 450, Cat® CG18 In-line 6, 4-cycle Natural Gas, Generator Set

Single

DESCRIPTION

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.Caterpillar is leading the power generation marketplace with Power Solutions engineered to deliver unmatched flexibility, expandability, reliability, and cost-effectiveness.Electric Power
