20KW Hi-Frequency Split Induction Heater w/ Timers 80-250KHz

Note: This model is 380-415 volt three phase.

IHG series 100 kHz to 1100 kHz high frequency induction heaters are among the latest products developed by Across International. They can quickly heat most metals that other frequencies can not heat efficiently, like aluminum and metal powders. And uniquely they can heat parts from a distance. These heaters are the ideal tools for fine steel wires (such as those used in dentistry) annealing, small precision shaft quenching, hard alloy saw blade brazing and metal powders melting.

Main Features

• Specially designed for heating and welding thin metal parts, blades and melting of small quantity of metallic materials, ultra fast.
• Ease of use: just plug in the power and connect the water cooling system, our simple instruction allows you to use the heater in 15 minutes.
• Precise control with digital output, frequency and current displays.
• Remote foot switch for safer operation.
• Dual automatic and manual modes.
• Optional graphite, MgO and SiO₂ crucibles available. (melting material decides crucible type, weight and size of the material decide crucible size)
• Frequency is non-adjustable, it depends on the coil design (diameter of turns, numbers of turns, copper tubing diameter and total length).
  
• ISO 9001:2008 registered manufacturer.

Safety Features

• Overvoltage protection: machine shuts down when input voltage is over 500V. Overvoltage light will turn on and buzzer will sound continuously. Alarm and light shut off automatically when voltage goes below 500V.
  
• Overheat protection: if sensor detects heat radiator temperature is over 55°C, machine will shut down, overheat light will turn on and buzzer will sound continuously. Increase water pressure or lower water temperature until alarm goes off itself.
  
• Overcurrent/malfunction protections: machine will shut down, indicator light turned on and buzzer sounds continuously if one of these situations occurs:
• One of the machine parts becomes overheated
• Interfering signal detected
• Short circuit between work pieces and induction coils
• Machine malfunctions
• Induction coils touching each other
• Input voltage is too low
  
• Low water pressure protection: if water pressure goes below 29 PSI, machine will shut down, water protection light will turn on and buzzer will sound continuously.

IMPORTANT!!

• Always wear protective gear and goggles when operating the machine. Crucibles must be covered all the time during operation. Across International is not responsible for any damage caused by misuse.
• Do not run no-load operation for a long period of time, it might cause damage to the machine.
• Circulating water must be pure, clean and below 45°C.
• Machine must be grounded properly all the time during operation.
• Do NOT use single-turn coil if coil diameter is smaller than 100 mm, it will cause high frequency damage to the machine.
• Thread tape (or related material) is absolutely prohibited during installation of induction coils.
