  • low frequency induction heating equipment

    low frequency induction heating equipment

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

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

    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

  • 250KW induction heater

    250KW induction heater

    250KW induction heating equipment with low frequency is good for big diameter billet heating and deep surface hardening.

    Drive board and IGBT connected directly, shorten signal transfer to reduce failure rate

    All fasteners are copper &stainless steel

    More water temperature&pressure monitoring,copper radiator for better cooling and anti-electrolysis

  • Integrated Induction Power Unit

    Integrated Induction Power Unit

    Good reliability: Perfect protection system, reliable components, soft switch technology

    Easy to operate and maintain: Module design and simple circuit construction

    Application in Forging,Heat treatment,Pipe bending,Hot extrusion,Braing,Shrink-fittin,Hardening etc

    Produced under ISO9001:2015 and CE certificate

    Integrated design, less installation space

  • 100-160KW low frequency induction heating generator

    100-160KW low frequency induction heating generator

    Duolin engineer team research and design separately. Machine can be used for hot forging,induction soldering, hardening and other metal related induction heating.

    Easy operate work panel to show the induction equipment work condition.

    LED lights to show the PCB board work,easy to find the problem and repair.
