Desiccant dryers are critical components of compressed air purification systems. Their core function is to remove moisture from the air using adsorbents, which serve as the key material in the drying process. The performance of the adsorbent directly determines the adsorption efficiency and cost-effectiveness of the equipment.
Currently, commonly used adsorbents in desiccant dryers include activated alumina, molecular sieves, and silica gel. Depending on the required level of air dryness—often referred to as the dew point requirement—several key indicators must be considered when selecting an adsorbent: water adsorption capacity, crush strength, attrition rate, and bulk density.
• Water Adsorption Capacity: This refers to the amount of water an adsorbent can retain. It can be divided into static and dynamic adsorption capacity. The higher the value, the stronger the adsorption performance.
• Crush Strength: This indicates the pressure an adsorbent can withstand per unit area. Higher crush strength means the adsorbent is less likely to break under mechanical stress.
• Attrition Rate: Typically, the attrition rate should be below 0.3%. A high attrition rate can generate excessive dust, which may negatively impact the quality of the treated air.
• Bulk Density: This refers to the weight of the adsorbent per unit volume and is essential for calculating the required amount of adsorbent for a given system.
The JOOZEO Dynamic Data Center utilizes key technical indicators to select the most suitable adsorbents. By analyzing customers’ specific operating conditions and process requirements, we provide customized adsorbent solutions to enhance production efficiency.
