SPH Small Induction Heater
SPH small induction heater features an electromagnetic induction coil mounted on an external column, capable of heating bearings weighing up to 40kg. The heater includes overheat protection, reducing the risk of damage to the electromagnetic induction coil and electronic components. In addition to temperature-controlled heating, a time-controlled heating mode is available for heating other ferromagnetic metal parts.
Product Details
A. The induction coil is located on the outer column of the heater, resulting in shorter heating time and lower energy consumption.
B. Foldable legs facilitate heating of bearings with larger diameters.
C. A magnetic temperature probe monitors the heating temperature in real time, preventing bearing overheating.
D. Easy-to-use control keys and an LED display are integrated into a movable control panel.
E. All three yokes are stored in a storage space within the heater base, reducing the risk of yoke damage or loss.
F. An integrated handle with the heater base facilitates transport.
Advantages of SPH Small Induction Heater:
- Compact and lightweight design: Weighing only 20.9kg, it is portable.
- Two-stage heating power settings and a small magnetic yoke enable safer and more energy-efficient heating of small bearings.
- Heating a 28kg bearing can be completed in 20 minutes.
- The preset heating target temperature is 110°C to prevent bearing overheating.
- Automatic demagnetization function.
Note: Our factory can provide customized induction heating machine solutions according to your specific requirements.
