The dehumidification principle of this kind of dryer is quite same to the heatless regenerative dryer, while the difference is that this kind is used in regenerative drying gas with lower pressure, which first after the receipt, and then into the regenerative tower to dehumidify the desiccant, so the heating device is added to the structure, and working procedures of receipt, cold blowing are added to the regenerative progress. The advantage of this type is that the energy consumption is very little, just be 6%, and the switching period is long, so the parts wear little to improve the reliability of the | The dehumidification principle of this kind of dryer is quite same to the heatless regenerative dryer, while the difference is that this kind is used in regenerative drying gas with lower pressure, which first after the receipt, and then into the regenerative tower to dehumidify the desiccant, so the heating device is added to the structure, and working procedures of receipt, cold blowing are added to the regenerative progress.
