DHX01 Series Electric Hot Air Heater

The DHX01 Series is a high-temperature electric hot air heater capable of producing hot air up to 700 °C for industrial heating, drying, and thermal processing applications.


Electric Hot Air Heater with Continuous Operation up to 700 °C



  • Electric hot air heater capable of producing continuous hot air up to 700 °C.
  • Operation can be stopped without a cooling cycle.
  • By using a dedicated control panel, hot-start operation is available to shorten startup time.
    (Power consumption during hot-start is minimal.)



電気ヒータで連続使用最高熱風温度700℃



◆連続使用最高700℃の熱風を吐出できる電気式熱風発生用ヒータです。



◆冷却運転なしで運転停止できます。



◆専用制御盤をご使用いただくことで、立上り時間を短縮できるホットスタート運転がご使用いただけます。

 (ホットスタート時の消費電力はわずかです。)
