DG450 Compact (3-Phase)

More output from a smaller footprint

The Cat® DG450 Compact gas generator set provides 450 ekW to support standby, demand response and limited-time power applications. Its compact in-line six-engine configuration delivers high power density with improved component accessibility.

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

Equipment Highlights

High power density

The in-line six-engine CG18 design delivers greater output from a smaller engine package, with more power packed into a smaller space.

Improved service access

A roomier enclosure means key components are easily accessible for inspections and maintenance.

Fewer engine components

An in-line six-engine configuration uses fewer parts than comparable V10 and V12 engines, helping simplify maintenance over the generator set lifecycle.

No aftertreatment required

Meeting non-emergency emissions requirements without aftertreatment eliminates associated maintenance and replacement costs.

Ultra-low NOx capability

Very low natural gas inlet pressure capability provides greater flexibility when integrating the generator set.

Expandable system options

Bolt-on attachments allow the generator set to accommodate additional system capabilities as operating needs change.
