Burners that use premix technology in combination with a high efficiency boiler maximize the efficiency of the heat cell and limit their emission of NOx, CO and CO2. With the recent enforcement of new emission standards for gas boilers in Europe, the US and Asia, premix technology offers the perfect solution to manufacturers who need to conform to the new regulations.
Combined with gas adaptive control electronics, premix burners offer the highest efficiency at lowest emissions. premix burners support high modulation ranges. Innovative features in the burner provide a stable flame signal, even at very low outputs.
