Difference between revisions of "Tubular Heaters"

These type of heaters are used for comfort heating, drying,  in ripening rooms, forced air dryers, recirculating ovens and heating  of cryogenic exhaust gases. The maximum sheath temperature is 850 deg F,  but the airflow will cool down the outlet air temperature to max. 500  deg F. If higher temperatures are required, a tubular heater with no  fins or a quartz / ceramic air heater is the choice. The outlet temperature can be as high as 1200 deg F and  the airflow is typically from 240 - 2200 FPM. These types of heaters are  used for recirculating ovens, drying or curing ovens, heat treating,  annealing or dehumidification. Heaters installed in a forced air duct,  are commonly known as duct heaters.
