Zimmerman was established in 1963 to build the first modern Tower Dryers, joining the FFI family in 1989, and then joining GSI Group, LLC in 2001. The Zimmerman Tower Design is a part of all GSI Tower Dryers, continuing the legacy of market leading technology.
GSI’s T-Series Tower Dryer design natively allows for easy heat recovery without the uneven heat issues of other designs, patented self-cleaning divider floor and quiet operation with the fans located inside the grain column, along with great service to back it up.
