Chillers for Induction Heating
Induction heating is a quick and precise process that allows intense heat to be applied selectively to parts of the workpiece where heat treatment is desired. Induction heating is generally suitable for all electrically conductive materials. A refrigerant based air cooled chiller is ideal for removal of concentrated heat from your process equipment. Our Koolant Koolers chiller systems work well with many applications including heat treating, heat induction and plasma spray torches. Since the chiller must operate in dusty and high ambient temperature environments, our chillers are ideal for these challenging applications.
Induction Heating – an efficient way to accurately heat metals
The laws of induction are the basis for all induction heating processes such as: induction hardening, induction tempering, induction annealing, induction brazing, and other hot forming technologies. Reliable water chilling equipment is required to maintain equipment component life in many different applications.
How does Induction Heating work?
During induction heating eddy currents are induced in an electrically conductive metallic workpiece by an alternating electromagnetic field. These currents are converted into heat by magnetic loss – or, simply put, the metal heats up due to the current flow produced in the workpiece. This enables induction heating to introduce heat directly into the workpiece rather than through connection from an external source, such as heating with a flame or in a furnace. This process thus achieves a high degree of energy efficiency. Additionally, heating can be accomplished by passing through non-conductive materials. The surrounding area is only heated indirectly.
Influences on Induction Heating
The depth of heating in the workpiece depends on the material properties of the workpiece. The frequency of the current supplied by the generator also has a significant influence on the depth of heating. Higher frequencies are particularly suitable for heating contours very accurately at a low depth of penetration in the workpiece. Lower frequencies are suitable for a higher depth of penetration.
Depending on the task, a detailed analysis must be performed in order to select the optimal generator for the induction heating task. Electric frequency being one of the key criteria for the success of induction heating process. However, the material, heating temperature, and production batch sizes also have a significant influence on the design of an induction heating solution. Next to the inductor, the correct water chiller is one of the most important system components to maintain long life for all work cell components. Our thermal engineers can work with you to properly size and recommend the Koolant Koolers model best suited for your application.
