CPCB-IV+▪ Thermal Management

Exhaust Heater

PWM-controlled electric exhaust heater that keeps DOC, DPF and SCR in their working window at light load. One-box design with built-in diagnostics and protection, no relays or fuses needed.

Where it is used

  • Low-load gensets
  • Cold starts
  • SCR light-off
  • DPF regeneration support
