Thermair, hot air generators consist of a shell and tube type heat exchanger which is duly insulated to prevent radiation losses. The ventilation blower fitted alongside blows fresh air over the combustion chamber and the set of smoke tubes. In oil / gas fired options, an imported mono-block type fully automatic burner is provided for combustion of fuel.

Thermair can also be offered in solid fuel firing options. A dust-proof, pre-wired control panel is also supplied as a standard supply to control the operation of the unit based on customer requirements.
