Mass Finishing Driers - Belt


Surface Preparation features a complete line of hot air belt driers. Belt driers are ideal for large and bulky parts, delicate parts that must not impinge each other and for components with difficult to reach cavities where drying media may lodge.

Hot air belt driers are designed to complete the finishing process by offering an effective means of drying wet components by passing them through a hot air tunnel. The drying takes place with hot air which is constantly circulated with a blower fan, uniformly heating the drying tunnel.

Key features of hot air belt driers include:

  • Operating temperature adjustable up to 280° F.
  • Speed of the belt drive is adjustable from 19 to 118 inches per minute
  • Units are heavily insulated resulting in energy savings
