Zimmerman was established in 1963 to build the first modern Tower Dryers. FFI purchased Zimmerman in 1989 and FFI/Zimmerman became a part of GSI in 2001. All FFI Modular Tower Dryers have their roots in the Zimmerman Tower Dryer Design and have been and will continue to be the market leader in grain drying technology alongside the Zimmerman tradition.
The FFI’s Modular Tower Dryer design natively allows for easy heat recovery without the uneven heat issues of other designs, as well as a patented self-cleaning divider floor and quiet operation with the fans located inside the grain column.
In addition to a quality product with exceptional design, GSI has the Dealers and Service Technicians to ensure your dryer works when you need it because we know how important that is; harvest is a short window of time and you depend on your dryer working at peak performance.
