Where does the advantage come from?
The energy consumption of a refrigeration dryer (pressure dewpoint +3°C) is about 2,5% compared to the power consumption of the compressor. The refrigeration dryer removes about 85% of the water load of the compressed air.
The energy consumption of a heated adsorption dryer is about 8,5% (pressure dewpoint -40°C). The adsorption dryer removes 14,9% of the remaining humidity in the compressed air.
The SPX Flow‚ HybriDryer is the logical combination of refrigeration- and adsorption technology and uses about 4% energy.
