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.
Vane Axial Fans
For application requiring high airflow at static pressures below 6”, 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 maximum air flow and reduced
turbulence to ensure smooth and consistent airflow.
All 24” and 28” vane axial fans also include an inlet venturi which
funnels air more efficiently into the fan. Venturis and grill guards are
corrosion-resistant painted for longer life.
Specifications
Inline Centrifugal Fans
Aeration jobs at high static such as with milo, wheat or rape seed
require special consideration. Aerating tall hopper tanks presents
another challenge. The inline centrifugal fan is designed to handle both
of these applications effectively.
Suited for higher static pressures, beyond the performance range of
vane axial fans, the inline centrifugal fan offers higher static
pressure capabilities to a 1750 rpm centrifugal fan at a lower cost.
Inline centrifugal fans make less noise than vane axial fans, and 1750 rpm centrifugal fans are even quieter.
Inline centrifugals can not be used with heaters due to their design.
Specifications
Centrifugal Fans
1750 RPM Centrifugal Fan
Built with a heavy galvanized steel, scroll-type housing and inverted
inlet venturi. A non-overloading
backward-inclined airfoil wheel provides high airflow with a long motor
life. These fans operate at a very low noise level and are designed to
accommodate a variety of heaters for use on drying bins where higher
capacities are required. Models are available from 5 - 50 HP with static
pressures up to 11”.
3500 RPM Centrifugal Fan
GSI also manufactures a 3500 RPM centrifugal fan designed to operate
in static pressures up to 22”. These fans are used primarily with tall
tanks or small grains tanks with high resistance to airflow.
Specifications
Vane Axial Downstream Heaters
Whether natural air-drying grain or heat drying, all GSI "drying" fans
have the option of adding a heater. 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” through 28” diameter, liquid propane, propane vapor or natural gas
models.
Specifications
Chi-Town Upstream Heaters
GSI's "Chi-Town" heater is a low to medium temperature grain drying
system that is typically used with GSI's centrifugal fans. 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.
Specifications
Centrifugal Downstream Heaters
GSI's downwind centrifugal burner is a high efficiency option to
compliment our high capacity centrifugal fans. Specially designed
burners are adjustable for uniform heating temperatures with a 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 4.2 million BTU/hr.
