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.
|CAPACITIES/HR||Up to 7,000 bph Dry & Cool @ 5 pt. removal|
|Fuel||LP or Natural Gas|
|Standard Grain Inverters|
|Standard Vacuum Cool Heat Recovery|
Vision controls offer simple operation, with an easy-to-read large color graphical touch display. Located on the dryer or remote with a few wires, these controls are design specifically for GSI grain dryers, giving you unmatched options and settings to get exactly what you need from your dryer control.
Eliminate over-dried grain and maximize drying efficiency and quality by using a GSI’s patented grain inverter. This system inverts all but the outside two inches of grain promoting higher test weights, maximum grain quality, and reduced fuel usage. The outside 2 inches of wet grain is dried using the heat which would have otherwise escaped the dryer, keeping your operation energy efficient. A convenient clean-out door provides easy, quick maintenance.
Improve your accuracy with the new static moisture sampler. Debris Guards ensure a trash-free sample while a SideKick Auger mixes and delivers a uniform representative sample to the test chamber. Get the most accurate results as the moisture reading used to monitor/calculate discharge grain moisture is only taken while the grain is static and not flowing.
One size does not fit all when it comes to drying grain, and that’s why GSI features a complete lineup of grain dryers. With the ability to dry in or out of bin, batch or continuous flow we have the dryer to fit your needs and maximize your profitability.

"I chose the GSI dryer because it’s extremely efficient and the Vision Control System makes it very simple to operate"Carl Ryan
Many years ago Carl Ryan realized that if he started harvest earlier he could bring in more bushels. Today he starts at 30% moisture and intends to be finished by 20%. Having grown up on a farm, he is very familiar with weather and head shatter losses. So it didn’t take him long to figure out that if he finishes harvest by 20% then he doesn’t have to deal with those other losses. “I think 26% is the optimum moisture to harvest. It balances the combine damage at higher moistures and the loss of yield from allowing it to dry in the field,” said Ryan.Full Story
"We decided on the GSI Tower Dryer because we wanted a dryer with the capacity to allow us to start harvest at 30% and get the crop in during good conditions with minimal loss"Craig & Brian Foutch
With big plans to carry on the success of their family farm, the Foutch brothers have always invested in their farm equipment, practices and grain systems. They are firm believers in keeping up with technology and quickly upgraded their combine to monitor their yields and grain moisture. Having this information at their fingertips made the brothers realize one thing; they needed to increase their drying capacity.Full Story
"I harvest early to capture my full yield, eliminate as much loss as possible, and ultimately to maximize profits"Jeff Gehrig - Spoon River Valley Farms
In 2010 Jeff Gehrig upgraded to a GSI T-Series 20100 Tower Dryer. He chose the Tower Dryer because of its efficiency and high capacity. Today, Gehrig approaches harvest with the mindset to start as early as possible and harvest as fast as possible to get the crop out of the field before it drops below 20%. “When my corn is still standing in the field and moisture drops below 20% the invisible, weather and head shatter losses are far more than the drying costs,” said Gehrig.Full Story
