Adsorption Dryer Housings

Description

Our ADS (Adsorption Housing Series) dryer housings are a robust and flexible solution for point-of-use air purification. Available across our product line, nearly all standard housings can be configured as ADS units—complete with integrated filter pads and desiccant media.

The ADS Series expands on the proven performance of our Disposable In-Line Adsorbers (DIA) and In-Line Column Assemblies (IACH/IAAH), offering enhanced serviceability, increased desiccant life, and superior media contact time—all while maintaining low pressure drop.

Key Features

• Easy desiccant replacement
• Longer service life and high adsorption efficiency
• Minimal pressure drop
• Compatible with pleated 3-micron post-filters for critical applications
• Standard housings with modified internals for loose-fill desiccant
• T-type design allows for easy installation and filter series integration
• Simple and cost-effective servicing

Desiccant Options

(See last page for full list of available adsorbents)

Silica Gel – We utilize an indicating silica gel which goes from a blue to pink when spent.  It provides maximum moisture adsorption and dew points down to -40°F when sized properly.

Molecular Sieve – Are crystalline, metallic aluminum silicates.  The type 4A offer exceptional water vapor adsorption characteristics.  Dewpoints are attainable to -40°F.

Carbon – We utilize coconut carbon which has high fiber content and surface area for added oil vapor adsorption efficiency.

Design:

ADS Series housings use a modified internal layout within our standard housings to accommodate loose-fill desiccant. Wet gas enters the housing and is directed down a central hollow stack to the base, where it is diffused evenly through a 25-micron stainless steel frit. The gas then flows upward through the desiccant bed, where moisture or oil vapor is adsorbed.  Before exiting the housing, the treated gas passes through a 5-micron filter pad with a support disc, minimizing the risk of desiccant media migration into downstream equipment.

The T-type configuration of the ADS Series simplifies installation, enabling easy integration with pre-filters and post-filters in a single footprint. This design streamlines servicing, making desiccant change-outs fast, convenient, and economical.

Nylon / Polycarbonate Version for Visual Monitoring

The nylon/poly version offers reliable performance in a compact and durable design. Clear bowls allow for effortless visual monitoring of desiccant color changes, taking the guesswork out of media life and ensuring timely replacement.

Key Features:

• Compact Design – Saves space and fits easily into tight installations
• Clear Bowls – Quick, visual indication of desiccant status
• Easy Mounting – Simplifies installation and maintenance

Perfect for environments where precision and reliability are essential.
