Now, there are three common methods for heating engineering workpieces, namely electromagnetic induction heating, ceramic sheet resistance heating, and flame heating (gas). Below, POLARIS-ETeK takes a Φ800X1000mm pipeline as an example. The conditions are: heating from room temperature to 200°C, and detailed analysis of the characteristics of the following three heating processes.

3.Technical advantages of the equipment
Energy-saving and high-efficiency technology leader
Electromagnetic induction heating is internationally recognized as the heating method with the highest conversion efficiency of electric heat.
Novel structure and unique performance
The electromagnetic heater can be reasonably arranged on the workpiece in sections, and the workpiece generates uniform skin effect heat. The two cooperate with each other and supplement together, so that the temperature distribution is uniform and moderate, the heat efficiency is high, and the loss is small.

Complete Computer Control Function
The variable frequency power supply control cabinet adopts full digital automatic control technology with high power factor and stable performance. It has dynamic and arbitrary adjustment settings of on-site power, temperature and frequency, soft start and soft stop functions, and failures such as phase loss, overcurrent, overvoltage, short circuit, etc. Automatically protect and recognize the display.
Reliable quality and durable
Superior structural design, unique high-performance materials, advanced manufacturing technology, and strict testing methods ensure performance quality and service life.
Easy to install and easy to use
The installation of the equipment does not require other auxiliary equipment, ordinary trucks can be transported, on-site operations only need to be connected to three-phase electricity, the electromagnetic wire is wound on the workpiece to be heated, and the temperature curve is set to start heating.
