In its simplest form the DryAir system consists of the following:
The Central Heating Unit (1) uses either a diesel, propane or natural gas fired hydronic water heater (2), pump (2) and controls (3).
The water heater (2) heats a glycol solution. The pump then circulates the heated fluid to the remote heat coils (8) at the bins.
Heat is transferred as intake air (12) is drawn through the heat coil (8) by the aeration fan (10). The heated, “desert-dry” air then continues to the bin via the flexible air tube (9) and aeration fan (10).
Air diffusion within the bin is accomplished using the existing aeration ducting (11). The heated air (13) absorbs moisture as it passes through the grain and exits as saturated air (14) through the top of the bin.
Setting of the flowrate of the heated fluid through the heat coil (8) establishes the desired heated air temperature (13) which can be entered into the DryAir calculator to determine an accurate timeline of when the drying process will be complete.
