Sullair Industrial Compressed Air Desiccant Dryers

Uses approximately 15 % of the process air during the regeneration process.

Dryers without heat input divert a small amount of dry process air from the drying vessel to regenerate the opposite vessel.

Uses approximately 7 % of the process air during the regeneration process.

Heated dryers use an additional heat source, which reduces the loss of process air during the regeneration process.

The additional heat source helps to improve the drying and regeneration process while saving energy.

Uses approximately 0 to 3 % of the process air during the regeneration process.

Blower purge and heated dryers use a combination of an additional heat source, air from a blower and little or no process air.

The three-tier method helps optimize drying and regeneration processes while reducing energy consumption, maximizing life-cycle energy cost savings.

Compressed, saturated air passes through vessel one, where the desiccant adsorbs moisture, lowering the dew point to expel dry compressed air.

Once vessel one reaches a set level of saturation, the air changes to pass through vessel two.

As the air passes through vessel two, vessel one dries and regenerates the desiccant material.

When vessel two reaches a set level of saturation, the air changes to pass through vessel one.
