Ground Pile Control Systems

We build Ground Pile Control Systems that operate fans to suction the tarp to the grain pile. They use a wind speed sensor input to a micro-controller that runs a VFD controlled fan motor. When the wind is greater than (2) miles per hour the first fan is started. This is ramped up and down with the VFD as the wind speed increases/decreases. Additional fans come on line as the wind speed further accelerates. We also build a skirt control panel mounted at the top platform to position the tarp so it is reliable and keeps the grain dry. All settings are adjustable with set-points for every fan.
