Multi-functional High-Frequency Heating Machine

High-frequency Induction Heating Device

• Adopts Fuji MOSFET tubes and Siemens Opak IGBT power tubes, utilizing the first-generation "single-control series resonance technology", which is simple and reliable.
• Allows adjustment of power and time during the heating and heat preservation process, helping to improve heating quality and repeatability while simplifying 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.

Additional Outstanding Features

• Equipped with all-solid-state IGBT frequency conversion and power adjustment, utilizing the second-generation "dual-regulation series resonance soft-switch control" technology to achieve automatic frequency tracking, ensuring high reliability.
• 100% duty cycle, capable of continuous 24-hour operation at maximum power heating.
• Features constant power and constant current control functions, enabling efficient and rapid heating to the greatest extent and optimizing the heating process of metal workpieces.
• Ultra-fast heating speed: for example, 1kg of platinum can be melted in just 50 seconds (using SL-45KW-B).
• Equipped with frequency modulation, automatic frequency compensation circuit, and digital high-precision power triggering function, significantly improving heating and welding stability. It is more suitable for heat penetration forging forming, quenching, tempering, and other heat treatments of large workpieces.

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.
