Reduced commissioning and maintenance costs thanks to fewer burners, plus built‑in redundancy on twin‑burner models for added reliability and flexibility.

    Independent valves & sensors

    Allows each heat exchanger to be isolated for easier servicing and uninterrupted operation.

      Low NOx burners

      Compliant with emissions regulations for cleaner, future‑proof performance.

        High efficiency modulating pumps (ErP A)

        Improves efficiency and temperature control while reducing energy use.

          Multi‑line graphical display

          Clear access to live data and settings for simple system control.

            BMS‑ready via Modbus
