30-50KW High Frequency 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.

9. Integrated design with water cooler, inductor, feeding system and three chanel sorting system, infrared sensor,less space for installation.

10. Good reliability, prefect protection system, reliable components, soft switch technology.

11. Customized local input power, 400V+/-10% 50Hz or 600V 60 Hz.

1. Research, design and produced under ISO 9001:2015 by Duolin team, quality and delivery time under control.

2. Machine cabinet sealing,protect the induction heating equipement under complex working environment.

3. Door switch design for safety.

4. Less interference to the power grid, do not need compensation capacitor: High power factor-more than 0.95.

5. Induction heating euipment start under any condition 100%.

6. DSP and HMI technology, display the machine work data and indicate the fault output.
