Nitrogen Protection Electric Drying Tunnel

The nitrogen protection electric drying tunnel comprises of housing, working chamber, heating system, gas pressure reducing control valve, and exhaust port, etc. Thin steel sheets are welded together into the housing, and the inner wall of working chamber is made of high-quality stainless steel sheets. Aluminum silicate is filled between the housing and the working chamber as a thermal insulation layer. Combined with the insulation sealing strip on the housing door and the outer frame of working chamber (with pinch device), the sealing property of the housing is certainly excellent. The working chamber is equipped with withdrawable three level screens.

The drying tunnel has digital display temperature control system installed on left top of the housing. It provides clear reading, easy adjustment, high controlling accuracy, simple structure, and safe and reliable operation. There are air inlet and exhaust port with control valve on the right side of housing to facilitate the adjustment of the flow of protective gas. The uniformity of temperature is ensured by the horizontal supplying strong blast circulation system.

  • Electrothermal Tunnel Drying LineThe electrothermal tunnel drying line is mainly used in food, chemical, electric, glass industries. It can use electrothermal heater or hot blast heater to dehydrate and dry workpiece at the maximum temperature of 300℃. The furnace is equipped with hydrofuge system and hot air circulation system, so continuous production can be realized.
  • Hot Blast Circulation Electrothermal Drying TunnelThe drying box is made up with A3 cold pressing carbon steel sheet and drawing or mirror stainless steel board. Aluminum silicate is filled between housing and working chamber. The far infrared heating tubes are installed at the bottom of drying box or in the air ducts on box sides. At the bottom mounted iron feet or pulleys (according to customers' requirements).
