Data Sheet 0315 - Vulcan Quartz Infra-Red Emitters Vulcan Quartz Quartz Infra-red Emitter Specifications Operation Quartz emitters use a resistive element positioned within a quartz tube. As current is applied to the element, it heats and emits infrared radiation through the quartz tube. Uniformity The primary output is medium wave infrared, which is augmented by a secondary long wave output from the tubes. 90% of the output is medium wave, which will vary according to the wattage. Power and Voltage Power range available from 250W to 1000W. Voltage range available from 110V to 240V. Quartz Emitter Dimensions Power Range Voltages Q5 123 x 62mm 150W to 500W 110V to 240V Features Thermocouple option Q10 248 x 62mm 250W to 1000W 110 to 240V Section through Q10 Quartz Infrared Emitters Fixings A thermocouple is not fitted as standard.

Accordingly we have developed an option to provide the basis for closed loop temperature control. This utilises a fast response mineral insulated thermocouple which senses the temperature local to the spiral and allows the development of an empirical relationship between indicated temperature and the product temperature. The spacing dimensions given here relate to applications where there is no relative movement between heater and product. The irradiation distance is a variable of 100-200mm. The spacing detail given is only intended as a guideline when designing systems outside these parameters consideration should be given to product temperature, uniformity required, irradiation distance and power intensity required. The thermocouple used is a K type with a maximum temperature capability of 1200 deg.C. The securing olive for the thermocouple is designed to allow adjustment for fine tuning to give exact watts densities at predetermined indicated temperatures. Sheet reflectors may be used in insulated or un-insulated format to support Q5 and Q10 units, however, we do recommend you check with our technical personnel prior to mounting this format.
