Characteristics
This burner has a built-in heat exchanger to utilize exhaust heat for preheating combustion air. Owing to its unique heat exchanging method, this burner has realized a high energy-saving effect. Also, owing to its direct ignition method, this burner has realized the turn-down ratio up to 1:5. Furthermore, this burner is free from ignition failure in the ON-OFF operation. This burner can also be used for indirect heating and direct heating.
