GSI Fans and Heaters GSI manufactures a complete line of aeration and grain conditioning systems to help maintain grain quality. Choose from a variety of high efficiency vane axial, centifugal and inline centrifugal fans and heaters all with features designed to reduce cost and boost performance.		Fan Specifications -------------------- Bin Flooring Transitions Transitions are available to connect GSI fans to bins, aeration ducts or concrete entrance ways Control Boxes Control boxes are weather resistant with heavy duty start and stop switches. Centrifugal fans utilize NEMA 4X fiberglass enclosures.. Heavy Duty Motors GSI uses super heavy-duty motors to withstand the years of use in a variety of climates and conditions. All GSI Heaters Include: Quad Pipe Train and Burner Design to allow the heater to work HI-temp or LOW-temp (down to 10 degree temp rise). Patented blue-burn optimizer on propane models. Transition high limit switch. Liquid filled pressure gauge. Automatic ignition shutoff after proof of flame for extended igniter life. Standard Heaters Features: Mechanical, normally closed, flame switch with time delay reset button. Deluxe Heaters Features: Solid-state flame sensing using flame conduction. Self-Diagnosing Smart Board with a 3-year warranty. 10 second purge delay. Large easy access door with clear view window. TopDry Series 2000 Fan and Heater The drying force behind our Top Dry system, this fan and heater combination features state-of-the-art controls for convenient and simple operation.

	Inline Centrifugal Fans Specifications Delicate drying jobs, such as milo, wheat or rape seed require special consideration. Aerating tall hopper tanks can be another challenge. The inline centrifugal fan is designed to handle both these applications effectively. Suited for high static pressures beyond the performance range of vane-axial fans, the inline centrifugal fan offers the same characteristics of a regular centrifugal fan, however it is much more economical. Sizes range from 1-1/2 HP to 15 HP, 18" through 28" diameters.

Vane-Axial Fans Specifications For applications requiring high airflow at low static pressures, GSI offers vane-axial fans in 12" dia. (3/4 HP) through 42" dia. (40 HP). The 12" through 28" (15 HP) units feature a 3450 RPM motor for increased fan performance and energy efficiency. Close fan blade tip clearance and stator vanes provide maximum air flow and reduced turbulence ensuring smooth consistent airflow. All 24" and larger vane axial fans include an inlet venturi which funnels air more efficiently into the fan.

	1750 RPM Centrifugal Fans Specifications GSI's 1750 RPM Centrifugal fans are built with a heavy galvanized steel, scroll-type housing and inverted inlet venturi. A non-overloading backward inclined aerofoil wheel provides high airflow with a long motor life. These fans operate at a reduced noise level and are designed to accommodate a variety of gas or electric heaters for use on drying bins where higher capacities are required. Models are available from 5-40 HP with static pressures up to 11". GSI also manufactures a 3500 RPM centrifugal fan designed to operate in static pressures up to 22" and is mostly used with tall tanks or small grains tanks with high resistance to airflow.

Vane-Axial Heaters Specifications Whether you're natural air drying or heat drying grain, all GSI drying fans give you the option of adding a heater if the need arises. With capacities up to 2.7 million BTU/hr., our vane axial fan and heater combination provide the best in high capacity grain drying. Vane axial heaters are available in 18" through 28" diameter, liquid propane, propane vapor or natural gas.

	"Chi-town" Style Heaters GSI's "Chi-town" heater is a low to medium temperature grain drying system typically used with GSI's centrifugal fans or the 26" vane axial fan. Capable of .3 to 1.1 million BTU/hr., and available in propane vapor or natural gas, "Chi-town" is perfect for the drying/aeration of rice, corn or other select grains.

Downwind Centrifugal Heaters Specifications GSI's downwind centrifugal burner is a high efficiency option to compliment our high capacity centrifugal fans. Specially designed burners are adjustible for uniform heating temperatures with your choice of liquid propane, propane vapor or natural gas. Available for GSI's 1750 RPM (10-40 HP) centrifugal models, the downwind centrifugal burner is capable of capacities up to 4.0 million BTU/hr.

	Electric Heaters The GSI electric heater is designed for low temperature drying and air dehumidification. It uses a three-stage, hi-low heat process with capacities up to 18kW. The electric heater is available for use on vane-axial and centrifugal fans and comes in 230 volt or 440 volt. It is ideal for conditioning wheat or other food grains, where low temperature and grain quality are crucial.

GSI also manufactures several flooring designs
to fit your particular aeration system and grain type.
