working principle

According to pressure swing adsorption principle, CNH refrigerated dryer is a compressed air drying device. Adsorption compressed air under pressure in the water, the compressed air to give a dry, purged with a portion of dry compressed air at reduced pressure adsorbents, the adsorbent is regenerated, the two towers alternating with each other, resulting in the drying cycle using compressed air, the compressed air pressure dew point is different, choose different adsorbents, commonly used adsorbents have activated alumina, molecular sieve.


reasonable adsorption tower structural design, with Lens function, intuitive use of the adsorbent work to ensure supply quality.

Set up automatic filling pressure equalizing process steps, reducing airflow impact on the adsorbent, the adsorbent will not pulverized.

Adopt imported PLC program controller, LCD, user-friendly design, touch keys, and automatic temperature control module, and work adjustment based on working time and the heating temperature regeneration
