A new drying technology, however, uses structured desiccant
, also known as Cerades™. Instead of many small beads, Cerades consists of solid, ceramic blocks that dry the compressed air as it flows through straight, structured tubes. Because the air flow meets very little resistance, this process is much more energy efficient.
Unlike the tiny beads that bounce around (and into each other) in a traditional adsorption dryer, structured, solid desiccant lasts a long time. This is particularly important because the decaying desiccant beads can negatively impact the dew point and the performance of the dryer. In addition, they produce a fine dust that not only has to be filtered out to maintain a high air quality but can also compromise the environment and the health of dryer operators.
Structured desiccant does not have this problem and delivers its users ISO 8573-1:2010 Class 2 air purity for particles without any extra filtration.
As a solid ceramic block, Cerades also offers greater installation and operational flexibility.
For example, it can be mounted horizontally and is able to handle an inlet temperature of 70°C. This, combined with the fact that it is vibration-resistant and takes up less space, allows a structured desiccant dryer to be used in a wide range of applications, for example in the transportation industry.
