The Problem with Conventional Drying: Traditional dual tank drying systems cycle between adsorption and regeneration every four hours – causing flow and temperature swings, dew point drift, valve wear, and constant operator attention.   WEIXIAN's Answer: Unit 22. A single, continuously rotating silica gel bed that eliminates switching entirely. A World First from WEIXIAN.   Key Advantages   8,000 hours/year continuous operation – no 4 hour tank switching   Stable air flow and temperature – no switching transients   Constant dew point at –65 °C ± 3 °C   Better, more consistent product quality   15–20+kWh lower plant overall power consumption   Simpler, more convenient operation
