Heatless Desiccant Dryer
The Airpol heatless desiccant dryer is designed for installations that require extremely dry compressed air or where there is a risk of pipework freezing. It is used, among others, in the electronics, chemical, food, and pharmaceutical industries, as well as in instrument air systems.
The dryer achieves a pressure dew point down to −70°C, effectively separating moisture from the compressed air. Built-in filters additionally remove solid particles and oil from the air, ensuring a safe medium for demanding process applications.
Very Low Dew Point
The dryer achieves a pressure dew point of −20°C, −40°C, or even −70°C, depending on the selected device series.
Continuous Two-Column Operation
Two columns filled with a sorbent bed operate alternately. While one column dries the compressed air, the other undergoes regeneration, ensuring an uninterrupted supply of dry air.
Air Purification
Integrated compressed air filters remove solid particles and oil, improving the quality of the medium and the safety of the installation's operation.
Low Pressure Drops
Large-capacity air receivers and large-diameter manifolds limit the flow velocity of the compressed air, helping to reduce pressure drops in the system.
Energy-Efficient Control
In versions with dew point measurement, the controller adjusts the length and frequency of the cycles to actual operating conditions. This helps reduce the consumption of dried air needed to regenerate the sorbent bed.
Simple Operation
The dryer's design is simple to operate and suited for continuous operation, allowing it to provide a stable supply of dry compressed air in demanding installations.
