Built to Perform
Easy to Operate
Touch Screen Controls
Dryer operation is performed with an Allen-Bradley CompactLogix™ Programmable Logic Controller (PLC). This provides a complete safety monitoring and trouble-shooting menu, and performs system verification and operator prompts during start-up and operation.
A large Allen-Bradley PanelView™ Plus 1000 touch screen controls all dryer functions and self-diagnoses dryer problems, eliminating the guesswork associated with traditional controllers. Zimmerman’s intuitive PLC design means that facility employees can be brought up to speed on how to operate the dryer quickly and efficiently.
Patented
Grain Inverters
Eliminate over-dried grain and maximize drying efficiency and quality. This patented system inverts all but the outside 2″ (50.8 mm) of grain promoting higher test weights, maximum grain quality, and reduced fuel usage. The outside layer 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.
High-Volume Airflow
Mixed-Flow Blowers
Zimmerman Tower Dryers are optimized to provide just the right amount of airflow. Too little airflow adversely affects capacity, too much airflow adversely affects the efficiency. Internally mounted,
these in-line mixed flow blowers operate at slow speeds, which means low noise levels, low electrical usage and long life.
Airflow from the blower is ducted across a Maxon Low Emission line burner, eliminating hot spots and achieving optimal efficiency with airflow and heat distribution.
Static Moisture Sampler
Improve your accuracy with the static moisture sampler. Debris guards ensure a trash-free sample and delivers a uniform representative sample to the test chamber. A blower system gently moves the grain out of the chamber, cleaning it each cycle. 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.

1 – Dimensions exclude outside catwalk, See models below for diameter with catwalk.
2 – Overall height includes 60″ discharge height but not include the 20″ inlet spout.
3 – Capacities listed are wet bushels/tonnes, for mature #2 shelled dent corn at listed moisture content and are estimates based on drying principles, field results and computer simulation. Variance may occur due to grain’s physiological factors (kernel size, chemical composition, variety, maturity), excessive fines, adverse weather conditions, etc.
