DRYING MODE THREE:
PRESSURE HEAT- Two Zone
(M, E or A Models)
Pressure Heat - Two Zone (SQM, SQE, and SQA models) is slightly less efficient than regular Full Heat drying, as lower drying temperatures in the bottom Plenum reduce efficiency. The benefit is an improvement to grain quality as the lower- moisture grain in the Lower Plenum is subjected to less heat. An increase in airflow restriction also gives a slight decrease in capacity and efficiency compared to the Modified Full Heat, Single Zone. Rollover info balloon.
