Quartz Heaters
Quartz heaters and ceramic heaters generate hot air by blowing or pulling air over a heated surface. Using quartz or ceramic as a heated surface, hot air up to 1500 deg F can be produced. The quartz tube air heater is mainly for industrial heating applications, while a ceramic air heater is also used for non-industrial heating applications (like comfort heating). In a quartz air heater, the resistance wire is mounted into a glass (quartz) tube, while a ceramic air heater is a resistance wire embedded into layers of ceramic fiber insulation. We do recommand a SCR for power switching, a PID controller (example: ETR 9090 from Ogden), and a flow / pressure controller to use with this quartz ceramic air heaters. The most common failures of these heaters occur because of insufficient air flow or because the process temperatures sensor is located too far downstream.
Quartz Tube Air Heater are manufactured in two versions; open or nozzled. A nozzled heater can be used for smaller wattage but the heat can be directed to a smaller target. For small target application like soldering (example: medical device packaging), the nozzle diameter can be as small as .065" for airflows of less than 25 SCFH.
