SPONSORED White paper: Hybrid Refrigerated/Desiccant Compressed Air Dryers
Kaeser Compressors’ whitepaper, "Hybrid Refrigerated/Desiccant Compressed Air Dryers" by compressed air experts Wayne Perry and David Phillips, explains how a hybrid dryer can reduce energy costs for large systems needing extremely dry air.
For those relatively few, but general large compressed air applications that need extremely dry air (down to -40 degrees Fahrenheit), there are several types of desiccant dyers to do the job. In many cases, the most effective and least costly to operate wil be a hybrid dryer system. The hybrid solution includes both refrigerated and desiccant systems in series. Refrigeration will typically remove 85% to 88% of the total amount of water, and the desiccant dryer is challenged with only the remaining 12% to 15% of the total water removal.
