What are Quartz Heating Elements?
Infrared radiation is used in radiant heating to warm surfaces directly. Infrared heat, a component of the electromagnetic spectrum with a frequency below visible light, is emitted and absorbed by all objects. More heat will radiate from hotter items. The majority of quartz heaters use this technology as their foundation.
The wavelength of these infrared rays varies depending on the use and the distance. Due to its high heat resistance and low heat absorption, quartz makes for an excellent heating element and electrical insulator.
How Quartz Heaters Work
Optical reflectors are used to focus this energy into precise patterns. Like light, infrared radiates from the heat source and disperses across a considerable area. This type of heating operates similarly to the sun, moving in parallel axes and even having the ability to traverse the vacuum of space. Because of this, quartz heating is unaffected by wind and effective at directly heating both people and things.
These heaters are appropriate for both indoor and outdoor heating, and because of their heat output, they are also quite successful at heating up large spaces.
An infrared heater known as a quartz heater produces heat that is then released from the heater by a heating element that is housed inside a quartz tube. In order to obtain the proper degree of intensity to heat the particular material required, the heating element generates heat at the relevant wavelength.
The tube's dual functions are to safeguard the heating element and to prevent convective heat loss. The way quartz heating works is that once the heating element gets extremely hot, a quick buildup of heat occurs in the quartz tube. The heat is released from the tube after it reaches the proper temperature.
It has been established that the heat produced by this method is of the perfect wavelength for the human body. Due to the infrared spectrum falling almost entirely outside the air's absorption spectrum, the heat from the heater is directly absorbed by nearby persons and objects, while very little heat is absorbed by the air itself.
Types of Quartz Heater Elements
Medium-wavelength tube heaters: Typically consist of a quartz tube with a heating element inside of it. These can be installed in banks to make sizable heating arrays suitable for many drying applications.
Short wavelength tube heaters
Similar to medium wavelength tube heaters, short wavelength tube heaters have an element housed inside a quartz tube. The fact that these components are constructed of tungsten and the quartz tubes are sealed with a noble gas makes a difference. These heaters work wonders for applications involving powder coating and metal.
Quartz panel heaters
The heater has a face made of fused quartz, and there is an embedded heating element slightly below the surface. Compared to tube heaters, these higher mass heaters excel in producing a consistent energy output over a larger surface area.
Surface tube heaters
These heaters are made by encircling a quartz tube with a heating element. The user can benefit from both convection and IR heating by placing the heating element outside rather than within the quartz tube. These heaters work best in furnace situations where a predetermined temperature must be reached in both the surrounding air and the target object.
Quartz lamp
Quartz lamp components have an aluminum casing with a polished reflector. Quartz lamp elements in infrared heaters frequently provide usable infrared light at wavelengths less than five micrometers. In comparison to other open wire-coil sources, tungsten enclosed filaments can run at a temperature of about 2500° K and emit more short wavelength radiation. Quartz lamp elements have a very high watt density and are frequently utilized in high speed production operations.
Quartz tube element
A quartz tube element is often built using a wrapped resistance coil that is passed through a number of parallel quartz tubes and then enclosed in a highly reflecting body, which is frequently constructed of aluminized steel. Quartz tube heating components are frequently utilized for the processing of heat-sensitive materials since they work best in radiant applications.
