Split-Type High-Frequency Induction Heating System | GWDL Series Industrial Heating

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

Component	Description
Power Supply Unit	Equipped with high-efficiency IGBT inverter modules (45–160 kW) for stable energy delivery.
Heating Unit (Inductor)	Water-cooled inductor with optimized coil design for rapid, uniform heating.
Control Panel	User-friendly interface with digital display, auto-tuning, power/time adjustment.
Auxiliary Cabinet	Includes control logic, safety interlocks, water circuit, and external IO interface.

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.
