What is the difference between an infrared heater and a quartz heater?
Actually, they are both infrared heaters, except quartz heaters emit higher temperatures with resistance wire inside a quartz tube. A quartz heater can reach the temperature for which it is designed in less that a second, however this time and temperature can be hard to control. A quartz heater can flash an ink impression in 1 to 3 seconds and be instantly off. Quartz heaters are most often used in automatic presses. An infrared panel heater is constantly on at somewhat lower temperatures, but can still flash plastisol in 4-8 seconds. Infrared panel heaters are used in both manual and automatic presses.
