Induction Heating System Overview

Induction Heating Power Supply

Dinghong possesses the core technology of medium frequency power supply. The parameters of the medium frequency power supply calculated and designed by it are more reasonable and reliable in use.

Induction Smelting Furnace

From the induction coil to the shell of our smelting furnace, we have always adhered to our original intention and never cut corners. We safeguard the safety of our customers with integrity.

Industrial Induction Heater

The industrial Induction Heater is deeply loved by customers for its compact size, simple operation and excellent performance. It has improved the working environment and the company's image.

Closed Cooling Tower

Closed cooling towers are the safety guardians in the medium-frequency heating process, and their quality will directly affect the safety and efficiency of the entire production. So it is very important to choose high-quality closed cooling towers.

Induction Furnace Spare Parts

Dinghong integrates upstream and downstream resources to customize and provide a complete set of medium frequency heating solutions for customers based on their specific needs.

TECHNOLOGY

Energy Saving & Power-Supply Technology of Induction Heating System

Proprietary Power Control Technology

We use internally developed series and parallel master control boards with independent intellectual property rights — leading domestic technology not sold externally. Key electrical components come from renowned international and domestic brands. Our self-developed computer smelting management system provides real-time data collection and alarm monitoring for stable, efficient operation.

Optimized Design & Enhanced Reliability

The power cabinet features a closed capacitor design with wide, low-loss output copper bars and premium sandblasted/passivated copper components. Layout and wiring follow strict standards for easy maintenance. All parameters exceed rated power by at least 1.3 times, with quick-blow fuses protecting the power supply and transformer.

Advanced Furnace Safety & Energy-Saving Features

Innovative gap-free rotation technology, goose-tail non-water-cooled magnetic yoke (85% coverage with high-permeability silicon steel), and dual leakage alarm system (DC + AC) prevent accidents. The induction coil uses seamless TU1 oxygen-free copper with 7-11 layers of insulation, integrated water-cooled rings, and Faraday short-circuit rings for uniform heating, longer lining life, and superior overall energy efficiency.
