USF Surface Preparation Group

International Surface Preparation offers the Walther Trowal line of mass finishing driers. After the mass finishing process the finished work pieces are typically wet and require drying.

International Surface Preparation offers these three series of Walther Trowal driers:
- G Series - Heated vibratory bowl style driers for stain-free drying and secondary polishing of the processed work pieces with the use of heated media. Click here for more information on the G Series.
- DLT Series - Rotary drum style driers typically used with a heated drying media. Parts are transported continuously through a rotating screen drum. Click here for more information on the DLT Series.
- BF-HL Series - Hot air tunnel belt driers. Processed parts are transported through a drying tunnel on a wire mesh belt as hot air is circulated via a blower fan evenly throughout the drying tunnel.
