New way to dry and aerate grain
"Our new system reduces static pressure by up to 2 in., resulting in up to 50% less drying time compared to conventional duct systems," says Herb Anderson, co-owner.
The Helfer System consists of a horizontal, Y-shaped duct positioned above the bin floor (the optional "Suspend-Air" mounting system lifts the duct high enough to allow a sweep unloading auger to operate underneath), and a vertical center section 6 to 10 ft. tall, depending on bin size. The circular ducts (horizontal and vertical) are 15 in. in dia. and made of expanded metal.
Cost to equip a 19 ft. dia. bin, for ex-ample, is $500. "One man working alone can install a complete above-floor system in less than an hour," says Anderson. "In bins already equipped with a perforated false drying floor, we suggest adding only the vertical Helfer duct at a cost of about $170."
For large bins, Grain Guard offers vertical "wall wings" to ensure rapid, uniform drying of grain in the lower part of the bin along the outside wall.
A "wall wing" consists of a louvered 8 ft. high duct with a solid back, a self-cleaning peaked cap, and an open bottom. It ties into a single port on back side which exhausts air through bin wall and outside. From 3 to 6 "wall wings" are attached to inside wall of large bins, depending on diameter.
Grain Guard offers an open core, double walled vertical "Rocket Duct" aerator for hopper-bottom bins with up to 10,000 bu. capacity. It's 100% self-cleaning ù the screen louvers face downward so seeds don't get caught in perforations. Self-leveling legs allow the Rocket Duct to adapt to any slope hopper. Available in 30 or 45 in. dia., and in 4, 6 or 8 ft. heights.
