เครื่องทำลมแห้ง (Air Dryer) แบบดูดความชื้น

เครื่องทำลมแห้งแบบดูดความชื้น ใช้ลมอัดผ่านห้องที่เต็มไปด้วยสารดูดความชื้นมักจะเปิดใช้งานอลูมินาหรือตะแกรงโมเลกุล สารดูดความชื้นดูดซับความชื้นในรูขุมขนนับล้านเพื่อดักจับมัน เครื่องเป่าลมกำลังใช้ตัวควบคุมอัจฉริยะและอากาศอัดจะเปลี่ยนการควบคุมห้องโดยการตั้งเวลาที่ปรับได้ในแผงควบคุม สารดูดความชื้นแบบเปียกนั้นถูกสร้างใหม่และทำให้แห้งโดยการเป่าลมร้อนอัดอากาศ

KXR Series

Working Principle

Heated regenerating desiccant dryers are adopted with techniques of twin tower variable pressure absorbing and heating regeneration. During the regeneration progress, the depressurized expanded dry air is heated to a certain degree to enable it with more absorbing capability while reducing the use of regenerated air compressed air is dried through one tower while the other desiccant tower is being regenerated. The principle of the heated regenerating desiccant dryer is: One absorbing tower performs absorbing under working pressure while another one distills some of the compressed air from the main pipe then depressurizes and heats is for regenerated use. The heated regenerated desiccant contains less water and improves the absorbing capability.

KXD Series

Working Principle  

The heatless regenerating dryer utilizes the desiccant selectable feature absorbing the water in the compressed air to dry the air. Because the desiccant will reach saturation after using for a certain time, it has to be regenerated by the dry air to restore its drying capability. The adsorption principle used in this design is simple, robust and flexible. Continuous drying is accomplished by the operation of two desiccant towers. Compressed air is dried through one tower while the other desiccant tower is being regenerated by using itself dried air decompresses to normal pressure. Two towers will switch their functions by a certain switch cycle to enable it’s continuous supplying dry air.

Technical Specification

   The large-capacity design ensures a stable outlet dew point that can be adapted to the aging of the desiccant and the load changes.
   Main parts use famous brands to guarantee the stability of the system.
   The integrated product enables the installation to be very easy.
