With HRS dryers, the desorption and cooling in the system variation is accomplished with the ambient air drawn in by the blower.

Compressed air will not be used during the desorption or the cooling phase. Since the desorption occurs in counter current flow, low energy consumption is required. The HRS is therefore the most energy efficient option.
