Supportati da oltre 50 anni di esperienza, i motori a gas Siemens forniscono soluzioni energetiche che vanno dal semplice motore a un impianto di generazione completo. I motori a gas Siemens sono progettati e costruiti per fornire potenza continua altamente efficiente per applicazioni di co- e tri-generazione. La serie Siemens H Engine rappresenta uno dei modi migliori per ridurre i costi energetici.

Benefici:

  • Incorpora il nuovo sistema di controllo integrato GCS-E
  • Combustione ad alta efficienza Miller Cycle
  • Basso costo del ciclo di vita
  • Progettato per un uso intensivo e continuo
  • Alta disponibilità
  • Parti motore standard e intercambiabili (testate, valvole, ecc.)
  • Flessibilità del carburante leader del settore
  • Ingombro compatto
  • Eccellente efficienza globale/termica
  • Basse emissioni
Caratteristiche del motore:

  • Ustione magra
  • Miller Cycle, quattro tempi
  • Collettori di scarico a secco
  • Turbocharged
  • Intercooler a due stadi
