Q1.How much is the regeneration temperature of molecular sieve , activated alumina , silica alumina gel and silica alumina gel (water resistant)? (air dryer)
A1：Activated alumina :160℃-190℃
Molecular sieve :200℃-250℃
Silica alumina gel:120℃-150℃
The dew point pressure can reach -60℃ in normal condition with silica alumina gel.
Q2：In addition to the quality of the product, what are the reason for the break ball in the air dryer?
A2：① Desiccant expose in liquid water, lower crush strength , incorrect filling way.
②Without voltage-sharing or blocked , overimpact.
③Crush strength is effected by the stirring bar while filling.
Q3.What is the dew point of using the activated alumina JZ-K1 in the air dryer?
A3：Dew point -30℃ to -40℃(dew point)
Dew point -20℃ C to -30℃C (pressure dew point)
Q4：What is the dew point of using the activated alumina JZ-K2 in the air dryer?
A4：Dew point -55℃ (dew point)
Dew point -45℃ (pressure dew point)
Q5:What products can reach the dew point-70℃ ?
A5: Molecuar sieve 13X or molecuar Sieve 13X plus activated alumina ( the activated alumina could protect the molecular sieve and dry).
Add: The dew point is -70 ℃, how to filling the molecular sieve, activated alumina and silica gel?
A:Bottom of bed：activated alumina；
middle of bed： silica alumina gel；
top of bed：molecular sieve.
Q6:Why the dew point is plummted after using the product for a while?
A6: Regeneration isn’t completely .
Q7: What the normal size of activated alumina could be used for the air dryer ?
A7: 3-5mm、4-6mm、5-7mm.
