Induction Heating Machines

Sohal Electric Works offers Induction Heating Machines as a solution to wastage of heat in fuel based heating process systems where the medium (air) itself consumes more than 50% of energy. Now replacing conventional technique with induction heating can save energy. Induction is a phenomenon to transfer electrical energy from a coil to another coil. Induction heating uses the same concept, the workpiece acts as another coil and consumes transferred energy itself that heats it up to the desired temperature. These machines are constructed on medium frequency topology. So the components can be heated. Common applications are annealing, hardening, forging of ferrous and non-ferrous metals. This solid state and durable machine is developed by years of hard work. All components and techniques used are up-to-date and tested. The transformer core is low loss soft ferrite and coils are copper wound with H-class covering and an extra insulating wall is provided to isolate output winding. The water-cooled design of transformer makes it more efficient. The inverter section incorporates high quality capacitors which has a Q-factor > 1000. The switching devices used are the fastest devices than their counterparts. To prevent any type of damage two hall sensors, a water sensor, a supply sensor and a saturation sensor is attached to its micro controller powered main board. An interface filter prevents line disturbance. A new type of exclusive circuit removes the MCBs repetitive tripping. Advantages of induction heating: controlled heating, selective heating, non-polluting, energy efficient, no `start up’ time, user friendly, and high speed of production. Salient features: digital display, touch control switches, on screen counter, auto/manual mode, fully solid state, robustly built, 100% duty cycle operation, application specific machines, large variation of load characteristics, controlled heating variable frequency, and load sensing self tuning.
