25KW Annealing Aluminum Welding CNC Intelligent Small Industrial High-Frequency Heating Machine

Product Overview

The GWDL Series is a split-type, intelligent high-frequency induction heating system designed for demanding industrial heating applications. Powered by dual-regulated IGBT/MOSFET frequency and power control, the system ensures automatic frequency tracking, precise temperature control, and 100% continuous duty operation.

Its modular (split) configuration separates the power supply unit and heating unit, allowing flexible installation, easier maintenance, and higher adaptability to various process layouts.

System Composition

Working Principle

• Electromagnetic Induction:
  High-frequency alternating current generates an oscillating magnetic field via the inductor.
  Conductive metal parts within this field produce eddy currents, generating heat internally and rapidly.
• Dual-Regulated Control:
  The system automatically adjusts both frequency (30–80 kHz) and power output to track load changes in real time, ensuring thermal stability even under fluctuating working conditions.
• Split-Type Advantage:
  Separates the control/power module from the heating head, minimizing electromagnetic interference and reducing space requirements at the work site.

Core Product Advantages

Outstanding Features:

• Adopts Fuji MOSFET tubes and Siemens Opak IGBT power tubes, and utilizes the first-generation "single-control series resonance technology", which is simple and reliable.
• The power and time of the heating and heat preservation process can be adjusted, which helps to improve heating quality and repeatability, and simplifies workers' operations and technical requirements.
• Easy installation: simply connect to a single-phase 220V or three-phase 380V power supply, and connect the water inlet and outlet. It can be completed within a few minutes.
• Extremely small footprint, simple operation, and can be learned in a few minutes. It is particularly safe, with an output voltage lower than 36V to eliminate the risk of high-voltage electric shock.
• No open flame, making it safer. It uses eddy currents to generate electromagnetic induction, heating only metal objects.
