| ZERO PURGE-TYPE, CDA Zero Purge Dryer |
| Features: |
| 1. Zero CDA lose in the procedure of regeneration, and non-moisture contamination. |
| 2. Adsorption downstream. |
| 3. Procedures of adsorption and regeneration in reverse direction |
| 4. Procedures of heating and cooling in same direction (upstream) |
| 5. Patent device for energy saving by utilizing of internal waste energy. |
| 6. Stable running performance, high dew point, replacing water-cooled type directly |
| Description: |
| 1. Zero CDA lose in the procedure of regeneration, and non-moisture contamination. |
| External air was used to heat the desiccant to 200℃ for desorption procedure and then, CDA was used to cool the desiccant. The CDA would be recycled back to the system. |
| 2. Adsorption downstream |
| The compressed air made the desiccant tight by flowing downstream during adsorption procedure. This would be able to promote the adsorption efficiency as well as the dew point performance at outlet. |
| 3. Procedure of adsorption and regeneration in reverse direction |
| To ensure there was no repeated adsorption and heating was not a waste of power. |
| 4. Procedure of heating and cooling in same direction(upstream) |
| To ensure there was no moisture contamination and no adsorption in advance during cooling procedure so that adsorption efficiency can be enhanced substantially 20% or more. |
| 5. Patent device for energy saving by reuse of internal waste energy |
| The heating stop was advanced by temperature control. Heating and cooling procedures in the same direction so that, during the cooling procedure, it synchronized to raise and reuse the internal waste heat produced during the heating procedure. A part of heating time would be replaced by 60% of cooling time to shorten 20% or more, and energy saving was 20% or more as well. |
| 6. Stable running performance, high dew point, and replacing water-cooled type directly |
| Traditional water-cooled dryers had serious problems with moisture contamination, and the quality of dew point was not stable. Zero Lose Dryer series type features:no contamination, stable dew point and more efficient on energy saving, so that it could replace the water-cooled dryer(general type-zero air consumption dryer) directly. |
