Now, electromagnetic heaters are widely used in the heating industry. However, how effective are they in saving electricity? This remains a concern for many companies and users. When we talk about the electricity-saving capabilities of electromagnetic heaters, we are referring to the reduction in waste compared to traditional resistance wire or quartz heating. To understand how effective electromagnetic heaters are in saving electricity, we need to be clear about the amount of electricity wasted by traditional resistance wire/quartz heating and why it is wasteful. Additionally, we must explain why electromagnetic heaters can save electricity.

Why Resistance Wire Heating Wastes Electrical Energy

In the traditional heating industry, resistance wire and quartz heating methods are commonly used. However, these traditional heating methods have low thermal efficiency. Resistance wire and quartz primarily heat up upon electrical activation, then transfer the heat to the barrel, thereby heating the material. The heat utilization rate of this heating process is only around 50%, with the other 50% dissipating into the air. The electrical energy loss in all traditional resistance wire heating methods is over 50%.

The Reasons and Benefits of Energy-Saving with Electromagnetic Heating

The principle of electromagnetic heaters is based on electromagnetic induction heating, which utilizes an internal heating method, meaning it heats the material itself rather than transferring heat. It achieves the heating of materials through the conversion of energy among electricity, magnetism, and heat. Additionally, the cylinder containing the material is wrapped with 20mm of insulation, which can be said to significantly reduce heat loss during the electromagnetic induction heating process, with a thermal energy utilization rate of over 98%.
