How to choose, refrigeration dryer or adsorption dryer?
Refrigeration dryer
Refrigeration dryer is based on the physical properties of wet air, making use of refrigeration technology to compress the compressed air and force cool the required dew point temperature below, which will turn the water vapor mist into liquid droplets, it will be drained to outside by the automatic drainage machine.
It easily block pipeline of water freezing, then compressed air can not pass, if evaporation temperature of the refrigerant is lower than zero, due to compressed air contains a lot of water, so the refrigerant evaporation temperature can only be set at more than zero, usually 3-5 ℃, so compressed air dew point after treating can not reach below zero , it can not meet requirements for vast majority of industries on the compressed air quality. what kind of hazard will bring when using refrigeration dryer for enterprises?
1. Unqualified compressed air to cause the defective products.
2. High energy consumption.
It would up to 10% energy consumption when the compressed air quality at class 5（-7℃). However，the PDP of existing refrigerated air dryer is above +20℃，thus it can hardly make profits for enterprise.
3. High loss.
Increasing equipment failure, maintain cost and defective products caused by the unqualified compressed air would result in high economy lost for company.
Adsorption dryer
Adsorption dryer can be divided into traditional twin towers adsorption dryer, module adsorption dryer and the modular-units adsorption dryer, modular-units is upgrading version of the module. therefore, here mainly analyze the principle and advantages&disadvantages between twin towers and modular-units.
Twin towers dryer
Twin towers adsorption dryer use two pressure vessel tank filled with adsorbent as working group. using water absorption of adsorbent characteristics, a working group absorb moisture under pressure, the other working group analytically regenerate under low pressure , and mutual switch when adsorption is saturated, finally cycle work. generally entering into the air from the bottom of the tank, outlet from upper end, it mainly use alumina as adsorbent. What are the shortcomings for using twin towers?
1. Unstable PDP
1.1 Unbalanced air flow cause to blind area availability of adsorbent；
1.2 Short-cut of air flow caused by the unbalanced，loose air flow；
1.3 “Tunnel effect” to cause the failure of adsorbent powder；
2. High energy consumption（above 15%）
2.1 Adsorbent requires 30% more ；
2.2 High pressure lost and energy consumption；
2.3 Low instantaneous desorption capacity but high air purge consumption；
3. Difficult maintenance
3.1 Clogged pipe，filter and silencer by powder；
3.2 Unexpected effects on the post machine by powder；
3.3 Difficult to replace the adsorbent.
Modular-units dryer
Biteman modular-units dryer uses two columns& multi-column modular-units as working group and absorption characteristics, a working group adsorb water content under pressure, another working group analytically regenerate under low pressure, then mutual switch when adsorption is saturated, finally cycle work. it main use molecular sieve as adsorbent, modular-units can be replaced independently. Its inlet from the back-end of equipment as adding intake buffer chamber and outlet pressure chamber. So, what is the different using modular-units dryer?

No matter what will be use for refrigeration dryer, twin tower dryer or modular-units dryer, enterprises ultimate goal is solve the problem of compressed air quality. However different industry has different requirements, so you should choose as the actual situation when choosing compressed air purification equipment. Of course, some companies have had compressed air treatment equipment, and then no longer need other equipments. In fact, this just like upgraded smart phone, constantly updated system , why not choose better one if there are better products, equipment, systems?
