induction heating coils design

MYD series induction heater to compare the resistant heat:

l  Uniform

l  High Speed

l  Energy Saving: 30-80%


l  Air cooling: working well at -10℃-40℃

l  Induction heating power: To heat the work job with insulation blanket around it. High heating speed and heating efficiency with little energy lost.

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

l  Soft induction coil: Easy to wind on different work piece.

l  The Removable opening Induction coil: easy to operate and move.

l  Temperature recorder: Record the whole heating curve and print it at spot.

l  Temperature Controller: Heating according to the heating requirement details with the ±3℃ tolerance.

Applications&using fields

Our MYD series heating system are air-cooled induction heating equipment with DSP system.

Their main applications are pipeline heat, pre-weld heat, post-weld heat treatment, stress relief, injection mold heating, annealing, etc.

l  Pre-heat:for coating, bending, fitting&unfitting, weld and thermal assembly.

l  Post-weld heat treatment: tank, boiler or other metal jobs

l  Heating: mold heating, shipboard, zinc bath, large& irregular metal parts

l  Pipeline heat: pipeline oil, pipeline gas, pipeline water, pipeline petrochemical and other pipeline material

The using fields involved are petrochemical, oil and gas pipelines, aerospace, shipbuilding, steel, tanks, boilers, vessels, pressure vessels, cylinders, metal structure, spatial structure, railway bridges, electricity water, mine construction, vehicle manufacturing, nuclear power, mining, plastics processing, energy saving process, mold, screw barrel industries,etc.
