Beko ACC 4 Heatless Desiccant Dryer

DRYPOINT^® XC | Heatless Desiccant Dryers

Regenerative desiccant dryers are frequently found in industrial applications around the world. These dryers use a desiccant material, which adsorbs the water vapor in the air stream. Heatless desiccant dryers utilize a small amount of dried air to regenerate the desiccant in one tower while the other tower dries the compressed air. DRYPOINT^® XC Series heatless desiccant dryers provide very low dew points, are designed around reducing energy and process waste, and provide a very user friendly interface.

Features & Benefits

How it works

Warm, moisture saturated air enters the dryer through the open inlet valve, a required coalescing pre-filter (not pictured) is installed before entering the drying tower . Air flows upward through the tower where the desiccant extracts and retains water vapor, thereby lowering the dew point, before exiting the top of the tower. The dry air passes through the outlet check valve and passes through the particulate post-filter (not pictured) before exiting the dryer to the air distribution system . A small amount of dry air is diverted from the outlet flow of the drying tower to be used in regenerating the other tower. This diverted air is controlled by the adjustable purge valve and exits into the regenerating tower at near atmospheric pressure. This dry air flows downward through the tower , absorbing water from the moisture laden desiccant, before exiting near the bottom of the tower. This moist purge air passes through the purge exhaust valve and is vented to open atmosphere through the muffler. After a set amount of time the air flow through the dryer will reverse, turning the drying tower into the regenerating tower.
