Optimised combustion chamber
The L series Ygnis boilers design includes optimised combustion chamber dimensions
and design characteristics that ensures the unit meets the strict Swiss standards against pollutants.
NOx levels are below 80mg/kWh for gas and 120mg/kWh for oil.
Fast distribution of gases ensures optimum and balanced heat transfer. The hydraulic design ensures natural circulation of water with no hot spots and no water flow restriction.
