“Direct” Hot Air Generators
They produce hot air with temperatures from 120°C up to 800°C, mixing it with the fuel combustion products. They are equipped with natural gas, LPG, diesel oil, fuel oil burners, modulating or two-stage type of operation for small powers. They can be pressurized or suction depending on the air to heat up is pushed or sucked through the machine. They are made both as autonomous units that heat ambient air, and in the recirculation version to heat already warm air.
Generally the construction foresees the internal lining in refractory material where the burner flame can develop. Between the external structure of the generator and the hearth there is a space for the passage of the process air. The process air also has the function of “cooling” the combustion chamber both internally and externally.
The construction types are customized according to the air temperatures, flow rates and the type of fuel.
