Heatless Combined Air Dryer
Product Features
1. Refrigeration system
Adopt internationally famous refrigeration compressor and high performance refrigeration components and other parts, and the system design is perfect.
2. Adsorption system
The tower body is designed and manufactured in accordance with the pressure vessel specification. Selection of domestic famous desiccant, high compressive strength, wear resistance, high temperature resistance, no hydrolysis. Special design is adopted to enable continuous gas supply when the adsorption tower is switched. The slow and safe charging procedure and time-delay switching design eliminates airflow pulsation, prevents the adsorbent from moving and mitigated the impact. Separate filling port and discharge port for easy replacement of adsorbent. Imported pneumatic butterfly valve is selected to ensure the stable operation of equipment.
3. Characteristics of control box
It adopts ATMEL’s high-performance microprocessor chip design. The panel is provided with a clear process flow chart, which can directly display the running state of the equipment. LED display: including operation cycle state, valve switching state and timing selection state display. Highly integrated, high reliability, high cost performance.
Heated Combined Air Dryer – Integrated Refrigerated & Desiccant Two-in-One Compressed Air Dryer
Heatless Combined Air Dryer: All-in-One Refrigeration + Heatless Desiccant Dryer for Versatile Dry Air Demand
Many small and medium-sized manufacturers face dual drying demands: general medium-dry air for regular production and ultra-low dew point air for precision processes. Purchasing separate refrigerated dryers and heatless desiccant dryers leads to extra equipment costs, larger floor occupation and complicated pipeline layout. The Heatless Combined Air Dryer from Sollant integrates refrigeration system and heatless regeneration adsorption tower into a single skid-mounted unit, delivering flexible multi-grade dry air output with simplified operation and lower overall investment.
Core Technical Parameters & Working Principle
This combined dryer adopts two-stage drying logic: the front refrigeration system removes most liquid water, then the rear heatless regeneration adsorption tower deeply removes residual moisture to achieve ≤-40℃ pressure dew point. It uses classic heatless regeneration technology with mature, stable operation logic and fewer heating-related wearing parts.
