Traditional adsorption dryers require the direct discharge of moisture-laden air generated during the purge regeneration stage. This gas loss is typically factored into the cost of the final dried air, leading to increased expenses. Additionally, the waste heat released during the compression stage is not effectively utilized, resulting in significant energy waste.
In response to the call for energy conservation and emission reduction, waste heat regeneration zero purge dryers have been increasingly adopted. However, to fully leverage the advantages of these dryers, higher demands are placed on the performance of the adsorbent. Traditional adsorbents, due to their limited capabilities, often lead to unstable dew points in the final product air, with their limitations becoming particularly pronounced in low-temperature operating environments.
Shanghai Jiuzhou‘s high-adsorption Activated Alumina JZ-K2 offers significant advantages over traditional activated alumina. Its specific surface area is more than 20% higher, providing stronger adsorption performance. Additionally, the regeneration temperature of Activated Alumina JZ-K2 is lower, allowing for sufficient regeneration using only compression waste heat. As a result, it exhibits higher adsorption capacity over its service life and a longer cycle lifespan.
Through extensive testing and application across multiple machine models, Shanghai Jiuzhou’s high-adsorption Activated Alumina JZ-K2 is suitable for both waste heat zero purge dryers and blower-type heated regeneration zero purge dryers, capable of consistently delivering product air with lower dew points.
For over 30 years,Joozeo has been engaged in the research, development, and production of adsorbent products, including activated alumina, molecular sieves, and carbon molecular sieves. The company is committed to the innovation and development of high-performance adsorbent materials, providing reliable support for advancing the industry’s green transformation.
