Main Air Ducts

Challow Crop Dryimng and Storage

Engineer designed and of proven strength and stability, the CHALLOW duct range has the high performance and specification to complement the management potential of the Drive-On Drying Floor with which they are generally but not exclusively installed. The plywood panelling which forms the smooth outer skin is T&G jointed for strength and pressure sealing. Between each gussetted hardwood frame is a slide-controlled port to the floor. The frame legs are bracketed to the level concrete floor and the sides are extended without cross bracings to provide safe unobstructed walkways within and over.

The smooth vertical faces readily allow internal dividing walls.

A variety of sizes are available to give the correct capacity for efficient air flow through the drying system.
