Centrifugal Fans

Sioux Steel′s centrifugal fan housings are manufactured with heavy duty 11 gauge sides resulting in significantly less vibration for a more stable platform. This adds longevity to the life of the fan.

All centrifugal fans are bench-tested prior to shipping in order to ensure that our customers are getting a high quality product that works properly from day one.

• 5 - 50 HP standard low-speed fans, with or without controls.
• Fan blades are solid welded, not stitched for longer life.
• Adjustable legs on fans allow easy leveling and support while giving more flexibility for adjusting to inconsistencies in a concrete pad.
• Special airfoil blades move more air due to the backward curved, non-overloading design.
• Fan wheels are statically and dynamically balanced for smooth, trouble-free operation.

Heater Options for Centrifugal Fans

Axial Fans

Sioux Steel′s axial fans cast aluminum airfoil blade ensures economical maximum airflow at lower static pressures. The hub on the blade prevents backflow air leakage at higher static pressures. The housing is designed with close tip clearance for maximum airflow. Airflow is increased by not allowing air to blow back through the blade and the housing for greater efficiency providing the most efficient axial fan on the market today.

• Plated screen guard is bolted over the air intake for safety.
• High quality motors for heavy duty dependable fan operation.
• 2 year warranty.

• 2 year limited warranty on all fans and heaters. This warranty comes standard on every fan and heater; there is no additional cost for this benefit. No matter the size, Sioux fans and heaters stand out as the best performing products in the industry!
• Sioux Axial Fans are engineered for grain drying at lower static pressures. Our fans easily adapt to heaters or can be used alone for natural air drying or for pressure aeration.

Heater Options for Axial Fans

High-Speed Centrifugal Fans

These fans use an inventive design to increase airflow which boosts fan performance, as well as saves time and money. The specialized design of high-speed centrifugal fans make them ideal for small grain aeration, deep grain depths, in situations with high static pressure, tall tanks and in small tanks with high resistance to airflow.

• 20 - 50 HP high-speed 3 phase fans.
• Enclosed motor.
• 3500 RPM
• Optimal for use on small grains, such as canola, wheat, popcorn, millet, rice, milo & sunflowers and situations where static pressure is high.

Ultra-Low EQM Heater

The Ultra-Low EQM Heater is available for 7.5-25hp Centrifugal Fans & 7.5-10hp Triumph Fans. The heaters are capable of a 1-10 degree temperature rise!

What does it do?

Equilibrium Moisture (EQM) is the temperature and humidity combination needed to bring or keep grain at a specific moisture. The Ultra-Low EQM Heater supplies EQM air, driving the grain moisture to the desired target moisture.

How does it work?

The Ultra-Low EQM Heater senses the temperature and relative humidity of the air being delivered to the bin, working to keep grain at the target moisture level.

• If the air is too wet, it raises the temperature of that air by 1 to 10 degrees to achieve Target Equilibrium Moisture (EQM).
• If the air is at target, it adds no heat.
• If the air is too dry, it reduces the amount of air delivered to the grain.

What are the safeguards?
To ensure the reliability of single phase motors when not using a VFD, the operator can limit the numbers of starts and stops of the motor. Limits can be set for the maximum and minimum allowable temperature, humidity, and equilibrium moisture.

How do you know what it's doing?
The Ultra-Low EQM control produces its own WiFi to interface to any smart phone, tablet, or computer. Your device will display the current conditions with gauges as well as graph conditions over a user selected timeframe.

Can I use the Ultra-Low EQM Heater with my bin fan?
The heater can be attached to Sioux Steel fans as well as competitor′s fans as a retrofit kit.

Can I use the Ultra-Low EQM Heater with a VFD?
The preferred equipment is with a VFD which enables slowing down the fan when the outside air is too dry. This prevents over-drying and stagnation of the drying front. If there is no VFD, the fan stops and starts to reduce the amount of air when the air is too dry.

Can I add moisture with the EQM Heater?
Moisture can be added over time. However, it takes much longer to add moisture than to remove moisture for most grains.
