Air-Cooled 40KW IGBT Induction heating machine for Heat treatment / Post Welding /Shrink Fitting

Heat Treatment PWHT Machine Post Welding Shrink Fitting Heating

Product Description:

The Air-Cooled Induction Heating Machine is an advanced electromagnetic heating system designed to eliminate the need for traditional water-cooling infrastructure. By utilizing a highly efficient forced-air cooling system, this equipment provides a flexible, portable, and maintenance-free heating solution for industrial applications where water sources are unavailable, restricted, or impractical. It delivers the same precise, rapid, and energy-efficient heating performance as conventional systems but with significantly reduced setup complexity.

Key advantages

Don't need Water Dependency: Completely removes the need for cooling towers, chillers, water pumps, or plumbing. Ideal for remote field operations, outdoor construction sites, and facilities with strict water usage regulations.
Rapid Deployment & Portability: Lightweight and compact design allows for quick installation and easy relocation. Simply plug in and start heating in minutes.
Low Maintenance & High Reliability: Eliminates common water-cooling issues such as scaling, clogging, corrosion, and freezing. No water filters or chemical treatments are required, drastically reducing downtime and maintenance costs.
Energy Efficient & Eco-Friendly: Converts electrical energy directly into heat within the workpiece with minimal loss. The closed-loop air cooling system prevents water waste and environmental contamination.
Precise Digital Control: Features a fully digital embedded control system with an intuitive Human-Machine Interface (HMI). Supports manual, automatic, and closed-loop temperature control modes for consistent, repeatable results.

Features:

Advanced Cooling System: High-performance air-cooled power modules and inductors ensure stable operation under continuous heavy loads.
Wide Frequency & Power Range: Available in various power outputs (e.g., 20kW to 200kW+) and frequency bands (e.g., 800Hz to 30kHz) to accommodate different workpiece sizes and heating depths.
Intelligent Protection: Built-in comprehensive alarm system monitors for over-current, over-voltage, phase loss, overheating, and abnormal loads to protect both the equipment and the operator.
Flexible Inductors: Compatible with soft cables, clamp-on coils, and custom-designed air-cooled inductors to easily adapt to complex geometries, pipes, and large structural components.
Data Recording & Integration: Optional multi-channel temperature recorders and PLC/RS-485 communication interfaces allow for real-time curve tracking, process documentation, and seamless integration into automated production lines.

Technical Parameters: DSP-40KW air cooled induction heating machine

Applications:

1. Welding & Construction Industry
This is one of the most common applications for portable air-cooled units, especially for field work where water is scarce.
Weld Preheating & Post-Weld Heat Treatment (PWHT):
Application: Preheating pipes, pressure vessels, and structural steel before welding to prevent cracking, and stress-relieving after welding.
Air-Cooled Advantage: In outdoor construction sites, pipelines, or shipyards, accessing water for traditional cooling is difficult. Air-cooled cables and blankets allow workers to simply plug in and start heating without carrying heavy water tanks or chillers.
Hydrogen Bake-Out:
Application: Heating welded areas to diffuse trapped hydrogen, preventing delayed cracking in high-strength steels.
Key Feature: Precise temperature control (up to 400°F/204°C for air-cooled cables) ensures safety compliance without the risk of water leaks near electrical welding equipment.
️ 2. Mechanical Maintenance & Assembly (MRO)
For maintenance teams in factories, mines, and power plants, air-cooled induction is a game-changer for heavy machinery.
Shrink Fitting (Thermal Assembly):
Application: Heating gears, bearings, couplings, or rotors so they expand and can be easily slipped onto a shaft. As they cool, they create a tight, interference fit.
Air-Cooled Advantage: Portable units can be brought directly to the machine. The rapid heating saves hours compared to using an oven or torch, and the lack of water means no mess in the workshop.
Bearing & Gear Removal (Disassembly):
Application: Quickly heating a seized bearing or gear to expand it for removal.
Key Feature: Induction heating targets the metal part specifically, leaving the shaft cool. This prevents damage to the shaft and avoids the use of dangerous open flames or sledgehammers.
3. Automotive & Manufacturing
In a production environment, air-cooled systems offer cleanliness and efficiency.
Brazing & Soldering:
Application: Joining metal parts (like AC compressor components, brake lines, or motor windings) using a filler metal.
Air-Cooled Advantage: Air-cooled inductors are often lighter and easier to integrate into robotic arms or automated assembly lines. They eliminate the risk of water leaks damaging sensitive electronic components or product surfaces.
Hot Forming & Straightening:
Application: Localized heating of metal bars or sheets to make them pliable for bending or straightening (e.g., correcting distorted shafts).
Key Feature: Fast cycle times increase throughput. The "water-free" aspect keeps the factory floor dry and safe for operators.
️ 4. Aerospace & Energy
High-value industries that require strict process control and safety.
Composite Curing & Bonding:
Application: Curing adhesives and composite materials used in aircraft structures.
Air-Cooled Advantage: Uniform heating without hot spots ensures the structural integrity of expensive aerospace materials. Air-cooled blankets are flexible and conform to complex curved surfaces (like fuselage sections).
Turbine Blade Repair:
Application: Heating turbine blades for coating removal or repair brazing.
Key Feature: Precision heating prevents warping of delicate, high-cost components.
