Most flow heater designs are limited to 800°C (1470°F) gas temperature. The unique patented design of the Kanthal Flow Heater therefore allows up to 300°C higher gas outlet temperature than existing conventional technologies. The design gives very good temperature stability (+/- 1°C) and heating efficiency. Other key features are the very compact design and very wide flow range. Compared to gas burners, electrical heaters offer a cleaner work environment, easier installation, and fewer safety risks.
