Desiccant dryers work on the principle of moisture always migrating to the driest medium possible. Therefore, water vapour is removed from compressed air by passing it over an adsorbent desiccant material. In the above shown CompAir air treatment product family image, the desiccant dryer is shown in the centre by the twin towers & these types of air dryers can cater for larger airflow volumes. The full range of desiccant dryers is shown below.
As the air contacts the adsorbent material, water vapour transfers from the wet air to the dry desiccant, however, adsorbent materials have a fixed adsorption capacity and once this capacity is reached, they must be regenerated or replaced.
Therefore, to provide a continuous supply of clean, dry compressed air, adsorbent dryers utilise two chambers of desiccant material and at any one time, whilst one chamber is on-line, drying the incoming compressed air, the other is either off-line, being regenerated or is re-pressurised, ready to come on-line.
All desiccant dryers remove water in this manner. The energy consumed by a desiccant dryer can be directly attributed to the method used to regenerate the adsorbent material. CompAir offer a comprehensive range using the latest technology to provide an energy efficient solution at the lowest life cycle costs. Our complete dryer range is produced in-house so the same quality, performance and efficiency standards delivered by our compressor ranges can now be enjoyed from the air treatment range, including the below advantages:
