Heated Desiccant Dryer

To achieve ultra-dry compressed air and prevent compressed air loss, it is essential to use highly absorbent desiccant materials with strong adsorption activity, especially at low moisture concentrations. Among the available industrial desiccants, molecular sieve and silica gel are considered the most effective options due to their superior moisture adsorption capabilities.

A key point to note is that while these materials are excellent at absorbing moisture, they are also resistant to releasing it. Therefore, the most effective method for fully regenerating these materials is through the application of high temperature during the regeneration process.

This process takes place in heated desiccant dryers, where air is drawn in through an independent blower (eliminating the need to use the compressed air from the package itself) and passed over a heating element. The resulting hot air is then directed through the desiccant material, effectively regenerating (fully drying) it. After the regeneration phase, the heater is deactivated, and once the desiccant is cooled, a small amount of dry air passes through the material to prepare it for the next moisture adsorption cycle.
