The induction heating equipment including:

1. Induction heating power

2. Induction coil (Clamp induction coil) or (Soft induction coil)

3. Temperature recorder

4. Thermocouple

5. Insulation Blanket

6. And other part.

Advantages:

1. Air cooling: Not water cooling, Convenience to install.

2. Temperature recorder: Record the whole heating curve

3. Flexible induction coil: Easy to wind on different working piece.

4. Temperature Controller: Keep the heating process same with PWHT requirement .

5. PLC touching screen: Intuitive to see and easy to operate.

6. Induction heating power: High heating speed and heating efficiency, energy Saving.
