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.

OF THERMOCOUPLE
The control aspects of infra-red heating are essential to the quality and repeatability
of the infra-red process.
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.
