IR Emitter Response

Halogen lamps (T3, Ruby T3, and Rapido™) have the ability to turn on and off almost instantly.  When power is applied, the resulting heat occurs very rapidly. Halogen lamps have a response time of less than three seconds. Compare this to other emitters with response time of minutes and even hours.  Quartz halogen lamps have a similar cool down curve.

The instant on/off feature yields a potential safety benefit to operators and to the product. In continuous applications (web, extrusion, conveyor), conventional hot wall heaters may burn the product in the event of a line stoppage. This is due to the high heat capacity and slow response. In some applications, it is necessary to physically move the heaters out of the way after a line stoppage.  Quartz halogen systems can be controlled to not burn the product in a line shut down situation. Maintenance can also begin within minutes (versus hours) in this system due to the rapid cool down.
