What are the desiccants of the adsorption dryer?

Adsorption dryer generally use silica gel, activated alumina, molecular sieve as a desiccant.

What are the characteristics of various desiccants?

Silicone is more susceptible to moisture deliquescence.

Activated alumina adsorption performance is very strong, very stable, encountered moisture is not deliquescence, and has high crushing strength and abrasion resistance, a wider range of applications.

Molecular sieves have a better drying performance due to a relative humidity of less than 20%, often only as a deep dry desiccant.
