Steel boiler body insulated with 80 mm high-density glass wool and tear-resistant outer covering, ensuring low heat losses.

Design pressure of 6 bar; higher pressures available on request.

Fully cooled pressurized combustion chamber with optimized return water distribution to prevent thermal stress. Offset burner configuration improves flame reversal, reduces flue gas pressure losses, and expands operating range.

Tube bundle positioned above the furnace to maintain high flue gas temperatures and minimize condensate formation.
