Vision Control System
The GSI Vision dryer control system features a wide array of settings that offers unparalleled options and control. Boasting a 10.4" TFT color touch screen with easy-to-use controls, the Vision can be remote-mounted, via a simple seven wire harness, up to 1000 feet away from the dryer.
Because safety and dependability are paramount for all GSI products, the Vision system features a low voltage safety circuit and a safety disconnect on every dryer. Each safety is monitored individually and its status displayed on-screen.
With no moving parts – timers, time delays, thermostats, etc. – the Vision system is less prone to wear-and-tear that leads to costly repairs and downtime. Plenum and grain temperatures can be modified on-screen. You can also change from High/Low to On/Off fire mode which allows plenum operation down to 5 degrees above ambient with a simple software switch.
The Vision also puts help at your fingertips when you need it most. Owner’s Manuals are available on-demand and on-screen at the control box. GSI Vision allows users to track the dryer’s history. All shut downs are logged with time and date information. This data can be saved to a flash memory card (via USB) for use on a home computer.
WatchDog System
WatchDog works with the GSI Vision dryer control system to allow remote monitoring of various dryer functions, such as moisture, temperature and dryer status, all from the convenience of a home or office computer. WatchDog is fully web-based capable, giving users the ability to monitor their dryers from anywhere with internet capabilities. Device can be controlled from a smart phone, tablet, laptop...
GSI/DMC Stir-Ator
GSI’s Stir-Ator machines provide the most thorough, systematic, and timetested stirring pattern on the market. Whether purchasing a new bin or updating present storage for drying, a Stir-Ator can cut drying time by 50% in a low temperature bin. A Stir-Ator can also help store grain by serving as a management tool for grain conditioning.
