Adsorption dryer

How does an adsorption dryer work?

The humid air passes through a compound that is called desiccant, meaning moisture absorber. Once this is saturated with water, it is necessary to dry this desiccant.

The column containing the moisture absorber is depressurized and the accumulated water is drained. After this operation the regeneration method depends on the type of adsorption dryer. 

There are two techniques:

• Heatless dryers
• Heat regeneration dryers

Each of these products has advantages and disadvantages that must be known to ensure the best effectiveness.

Adsorption dryers with regeneration without heat input

The special feature of a heatless adsorption dryer is that a part of the dried compressed air stream is taken and used for regeneration purposes, which considerably reduces the compressed air loss and the operating costs.

Adsorption dryers with heat regeneration

In the context of an adsorption dryer with regeneration by heat input operating according to the dynamic adsorption principle. As with any adsorption dryer the wet compressed air flows through a desiccant bed. The moisture is then retained. 

In this context, the use of two parallel adsorption columns with alternating functions guarantees a permanent supply of dry air. An adsorber is always available to dry the compressed air. The second adsorber is regenerated at the same time.

The advantages of using an adsorption dryer

Superior reliability

Adsorption dryers have the ability to remove moisture from compressed air at a pressure dew point of up to -40°C/-40°F. This prevents the formation of condensation and protects your machines.

A formidable efficiency

In this type of dryer, the adapted size of the pipes and valves guarantees a limited pressure drop.This system allows to increase the efficiency of the system while reducing the energy consumption, different options are available.

Low maintenance

The dryers we offer have a limited footprint thanks to their "all-in-one" design. Delivered ready to use, they are quick to install to minimize production downtime. All internal components are easily accessible for easy maintenance. An interval of three years is the minimum between each maintenance.
