Air-cooled induction heaters are a type of induction heating machine that uses air as the power source and the cooling medium of the heating station. There is no need to install an additional cooling water system, and it is flexible and easy to use, so it can save users’ initial investment and daily maintenance costs.
KETCHAN induction air-cooled induction heaters are suitable for applications that require low-to-medium power and frequency and can be used to inductively heat inaccessible workpieces in the field without a cooling water source. Such as pre-welding preheating, post-welding heat treatment, and pipeline heating of large and special-shaped metal workpieces; disassembly, installation and maintenance of large electromechanical equipment, etc.

air-cooled induction heater Features
- It use air-cooled induction coils and induction heating power supplies that do not need water cooling systems, which reduces the cost and complexity of installation and maintenance.
- Fast and precise power control, allows for consistent and uniform heating of the workpieces.
- Have advanced and intuitive user interfaces that enable easy programming and monitoring of the heating process.
- Have built-in safety and diagnostic features that protect the equipment and the operators from overheating, overvoltage, overcurrent, and other faults.
- Have a flexible and wide range of load impedance matching, which means they can adapt to different coil designs and workpiece shapes.
- More compact and portable than water-cooled machines, as they do not have bulky water tanks, pumps, and hoses.
- Environmentally friendly, as they do not consume water or produce wastewater.
- Easier to operate and maintain, as they do not require regular cleaning, refilling, or monitoring of the cooling system.
- The heating belt itself does not generate heat, and there will be no scalding accidents caused by the operator’s negligence, and its applicability and safety are higher.
Applications
- Pipeline preheating and post-weld heat treatment: It can be used to preheat large pipes before welding and to perform stress relief or tempering after welding. This can improve the quality and strength of the welds, reduce the risk of cracking, and increase the corrosion resistance of the pipes.
- Pipeline anticorrosive coating: It can be used to heat the pipes before applying a protective coating, such as epoxy or polyethylene. This can enhance the adhesion and durability of the coating, and prevent moisture and oxygen from reaching the metal surface.
- Shrink fitting: It can be used to heat metal parts that need to be fitted into other parts, such as bearings, gears, shafts, and couplings. This can expand the inner part and allow it to slide over the outer part. When the inner part cools down, it contracts and forms a tight fit with the outer part.
- Medium heating: heat transfer oil, industrial water, hot water boiler, chemical reaction kettle, hot air heating, etc.
