Electric heater Hypersonic

Gas heaters do not turn on/off and warm up with the same efficiency and rapidness as electric heating solutions. These extreme high temperature applications are largely for R&D research projects. Electric heaters have many advantages that researchers benefit from including the ability to ramp up the temperature of the air stream very quickly. Gas heaters put undesirable byproducts into the air stream. Burn a gas and you turn it into carbon dioxide and water vapor. A few other things burn that are not too attractive. If you’re running a sensitive test then you probably don’t want those contaminants in your airstream. You can use a heat exchange but then that represents another barrier to rapid temperature ramp. If your test can’t accept the products of combustion and you need a rapid temperature ramp then gas is not for you.
