AERATION AND GRAIN CONDITIONING

PROVEN & DEPENDABLE The demands of farming are never-ending. Maintaining consistent grain quality is essential to long-term profitability and viability. GSI manufactures a complete line of aeration and grain-conditioning systems to help maintain grain quality in any operation. Never satisfied with the status quo, for over 40 years we have been driven to provide top-of-the-line products that will protect, condition and move the grain you work so hard to produce. As the pioneers in grain conditioning, we've set the industry standard with forward-thinking solutions designed to make you more...

CHOOSING THE RIGHT AERATION SYSTEM Having the right size of fan and drying system for your specific operation is key. Too much airflow can be as bad - sometimes even worse - than too little airflow. GSI manufactures a complete line of rugged aeration and grain conditioning systems to help maintain grain quality. Choose from a variety of high efficiency vane axial, centrifugal, and inline centrifugal fans and heaters, all with features designed to reduce costs and boost performance. No matter the fan size or type, our network of experienced dealers is the most knowledgeable in the field to...

AERATION FANS VANE AXIAL FANS For application requiring high airflow at static pressures below 6” (depending on bin diameter), GSI offers vane axial fans in 12” diameter (1 HP) through 28” diameter (15 HP). Vane axial fans 18” and smaller use cast aluminum blades. Vane axial fans 24” through 28” use durable composite airfoil blades that are lightweight for easy starting and function well in this type of environment. The 12” through 28” (1-15 HP) units feature a 3450 RPM motor for increased fan performance and energy efficiency. Close fan blade tip clearance and straightening vanes provide...

VANE AXIAL FANS - 3450 RPM GSI fans are engineered for the highest level of performance, durability, and energy efficiency Each fan is factory tested for optimal operation. Charts: cfm @ static pressure in inches.

CENTRIFUGAL DOWNSTREAM HEATERS VANE AXIAL CHI-TOWNDOWNSTREAM HEATERS UPSTREAM HEATERS For use as a medium to high temperature downstream on axial fans or with deluxe models as a low temperature, equilibrium or medium temperature burner on 1750 RPM centrifugal fans. With capacities up to 3.0 million BTU/hr., our vane axial fan and heater combination provides the very best in high capacity grain drying. Vane axial heaters are available in 18” to 28” dia., liquid propane, propane vapor or natural gas models. GSI's “Chi-Town” heater is a low or medium temperature burner for use only...

COMPLETE YOUR GSI SYSTEM MATERIAL HANDLING When determining the best system for your operation, we know that what is protected inside the bin is what counts the most. Every product we design, engineer and build is based on this foundation. Grain in the overhead chamber is dried by a large fan and heater then dumped to a holding area below. An aeration fan below captures heat from this previously dried grain, and pushes it upward to help dry the next load. This recycling of heat increases efficiency, which greatly reduces drying costs. GSI’s material handling line includes bucket elevators,...
