IL Air Direct-Combustion Heating Burner Linear Burner Gas Burner
Product Description
IL Air Direct-combustion Heating Burner
IL series burners are designed by Comtherm (U.K) to heat fresh air, medium & low-temperature air (direct combustion). They are used for processes such as heating, drying or curing for the environment or objects in medical, food and chemical industries. The burners may also be installed at the lower section of the steam or hot-water preheating section to ensure higher heating temperature.
Product Features
Designed for direct-combustion air heating and medium/low temperature drying;Low CO, NOx emissions;Modular design for power (rated power: 240kW/ft);Short flame length (max. length: 700mm);Burners meet ANSI/SCA standards;Regulation ratio of the burner is up to 30:1.
