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.
