There are numerous industrial processes that use heating and many of those applications are well suited to the use of infrared. These range from simple drying processes to more complex forming processes and more. This post discusses industrial infrared heaters, their applications, and the benefits of infrared heating technology compared to other heating technologies.
Infrared heating technology
There are three main forms of heat transfer: conduction, convection and radiation. Infrared heating is a form of radiation heat transfer, meaning it consists of electromagnetic waves traveling from the source to the target. To generate infrared heat, an electric current is passed through a metal heating element. The wavelength of the infrared energy generated depends on the thickness and material of the heating element. This wavelength of infrared energy is measured in microns and heaters are typically manufactured to produce one of three energy ranges:
Benefits of infrared heaters
Below are some benefits of infrared heating compared to other heating technologies:
Because energy is transferred directly from the heater to the target object, infrared heating systems can be more efficient and require less energy to achieve similar results.
Infrared heaters are electrically operated, allowing for controls that respond quickly and accurately. This creates more consistent production and product quality. These heaters can be compactly designed and installed in small spaces.
Maintenance is minimal, reducing long-term maintenance costs.
There is less wasted heat since it is not necessary to preheat the air inside an oven for the process to be effective. Overall, these systems are extremely flexible, can be easily controlled, and help you overcome challenges related to product quality and production time.
Applications of industrial infrared heaters
Some applications where the use of infrared heating has been shown to be beneficial:
- Paint drying and curing
- Heating and shaping of plastics
- Adhesive drying
- Glass manufacturing: laminated, bent and annealed
- Screen printing
- Textile Production
If you are a manufacturer looking to invest in infrared heating, make sure you purchase it from a reliable manufacturer and supplier. Make sure the manufacturer understands your requirements and that the heater fits your application exactly. Casso-Solar Technologies is one of the leading manufacturers of industrial infrared ovens.
