Turbulator® Tube Bars

Turbulator® Tube™ Bars
Turbulator Tube bars increase the drying rate and decrease the cross-machine temperature variation of dryers.

The patented design induces turbulence in the rimming layer of condensate for increased heat transfer, and the axial configuration delivers uniform drying across the machine.

US Patent Nos. 7,028,756 and 7,673395

Optimizing Performance

Turbulator Tube bars deliver the best performance when the condensate layer is at its optimum thickness. Kadant Johnson R&D has conducted exhaustive testing to determine the optimal syphon configuration and height for different applications. Operating with the right bar and syphon combination maximizes the operating range, capacity, and uniformity of dryer heat transfer.
