The process of removing the adsorbed water from desiccant media is very costly. Filtered and dried air is an expensive carrier and should therefore be used not only to regenerate the desiccant, but also for other purposes. The desiccant regeneration is facilitated under the conditions of a higher temperature.
For example, at a temperature above 180°C, the regeneration of the desiccant consumes only 50% of the energy required with heatless regeneration.
Heat regenerated adsorption dryers are divided into three groups:
- Dryers with built-in heaters
- Dryers with external heating elements and blowers
- Heat-Of-Compression System, in which the high temperature of the outlet compressed air is used for the desiccant regeneration
- Low costs of operation
- Easy installation and maintenance service
- Compact design
- Stable and constant dew point
- Complete unit includes dryer, inlet filter and dust filter
