IGBT Induction Heating Machine

1. Good start up performance: IGBT MF induction power supply apply series resonance technology so it can be starts up 100% under any condition.

2. Less indterface to power grid: Less harmonic current and high power factor, Power factoer remaining 0.95 above during machine running.

3. Low energy consumption: in series resonant circuit,voltage at inductor high and current low so energy loss is very low; Soft switch technology applied then switch loss is very low.

4. Water cooled by heat exchanger: Using distilled water as circulating water to avoid sediment and clog of hose.

5. Good reliability: IGBT is a self turn-off transistor that ensures incersion with suvvess and takes protection instantly; IGBT used form Infineon world-renowned manufacturer.

6. High conversion efficiency more than 97.5%: IGBT(Insulated Gate Bipolar Transistor)inversion technology.

7. Energy saving up to 15%-30% compared with SCR technology induction machine: LC series resonance circuit and voltage feedback design, low energy comsumption.

8. Cooper &stainless steel fasteners and radiator, better cooling and anti-electrolysis.

1: For billet full preheating or local induction heating before hot forging or forming, diameter range wide up to 200mm.

2: Pneumatic pusher, chain delivery system, pick up system three channel and Infrared thermometer system are available.

3: Well designed winding process and high quality copper tube brings result of high efficiency and energy saging.

4: Quick change connection enables replacement heating furnace conveniently.

5: PLC to realize the automatic, save labor and improve the production.
