Everything You Need to Know About Desiccant

Everything You Need to Know About Desiccant Drying If you work in the plastic processing industry, you know resin can begin to absorb moisture from the atmosphere throughout the procedures. Although non-hygroscopic resins such as PVC, polystyrene, polyethylene and polypropylene can contain moisture only on the surface, most engineering plastics are more or less hygroscopic.

Desiccant Air Dryer System | Quincy Compressor

Desiccant air dryers work in conjunction with an industrial air compressor. Their dual tower design allows you to time drying operations to a standard NEMA cycle, in which the one tower regenerates (purges) while the other performs the drying function. This prolongs desiccant life and allows for continuous operation for extended periods.

Regenerative Desiccant Compressed Air Dryers

Compressed air is dried to prevent condensation and corrosion which can disrupt manufacturing processes and contaminate products. Water is the primary promotor of chemical reactions and physical erosion in compressed air systems. 1 A myriad of desiccant dryer designs have been devised to provide "commercially dry" air, air having a dew point of -40°F or less, to prevent corrosion. 2

Tips on Choosing the Right Compressed Air

Heatless desiccant dryers use the dry air generated by the dryer to remove water vapor from the desiccant material. The major advantage of this technology is the reduced dependence on excessive outside services (e.g., steam, electricity, or gas) for heat. A regenerative desiccant dryer can be conveniently located near the point-of-use to deliver dry compressed air at dew points to -100°F (-73

Air dryer types: Refrigerated, desiccant, and

Desiccant air dryers work on a different principle—they adsorb moisture from the air stream and onto a desiccant material in a reversible process. They produce low dew points, so they are a good choice in subfreezing conditions or when processes require extremely dry air. Two types are heatless and heated.

How a Compressed Air Desiccant Dryer Works. Innovative Compressed Air Desiccant Dryers. The term desiccant dryer can refer to a broad range of compressed air dryers which are also known as heat regenerative dryer, twin tower dryers or adsorption dryers. The compressed air is passed through a pressure vessel with two towers or chambers in a modular dryer. These are filled with a media such

Resin Dryers: What do they do, and how do

In desiccant dryers made by Conair, desiccant is formed into the shape of a continuously rotating wheel. A closed loop of air moves from the dryer, through the hopper to collect moisture, then back through the desiccant wheel, which removes the moisture, leaving the air stream dry and ready to recirculate. The wheel rotates constantly so that, while one part of it is removing moisture from

Desiccant dryer: It may be costing you more

Desiccant units will consume about 2 to 3 kW of energy for every 100 cfm of dryer rating, compared to about 0.8 kW per 100 cfm for refrigerated dryers—almost 4 times as much! But if you have a desiccant style air dryer in lightly loaded conditions, it may be costing you more than you think.

How the Bendix AD-9 Works: AnythingTruck.com,

With an AD-9 air dryer installed, contaminants enter the supply port of the air dryer end cover. As the compressed air travels through the end cover assembly, its direction of flow changes several times causing contaminants to condense and drop to the bottom of the air dryer end cover. The compressed air exits the end cover and flows into the desiccant cartridge where it flows through an oil

Instrument Air Dryer Types – How Industrial Air

Heatless Air Dryer Working Principle. Heatless desiccant air dryers use a desiccant in twin towers – one for drying, and the other for regeneration. Wet compressed air enters the drying tower and passes over the desiccant which adsorbs it and exits as dry air (dew point between –40 and –100° F). The regenerating tower recovers the

Compressed air dryer - Wikipedia

Compressed air dryers are special types of filter systems that are specifically designed to remove the water that is inherent in compressed air. The process of compressing air raises its temperature and concentrates atmospheric contaminants, primarily water vapor. Consequently, the compressed air is generally at an elevated temperature and relative humidity.

How Does an Air Dryer Work? | Generon

How does a refrigerated air dryer work? Refrigerant types work on the principle of reducing moisture by cooling the air and condensing the moisture. The condensed moisture is then drained off. The cooled, dry air is then blown out while the warmer, moist air is pre-cooled and taken into the system. In this case, the air is cooled by coolants that run continuously to keep the system at a

Types of Compressed Air Dryers | Quincy

Desiccant dryers get their name from the hygroscopic drying agent contained within. Basically, a desiccant dryer works as follows: Compressed air is sent through a vessel that contains a pair of towers, both of which are filled with a certain drying agent, such as silica gel or activated alumina.

Types of Compressed Air Dryers Part 2:

In externally heated regenerative desiccant dryers, the purge air is heated to an elevated temperature and then passes through the desiccant bed. The amount of purge air is approximately 5-10% of the air flow through the dryer. The purge air from the compressed air system can be eliminated if a blower is used for the circulation of heated atmospheric air through the desiccant bed. To protect

Energy Savings Result from Compressed Air

Desiccant dryers, which provide air with a pressure dew point ranging from -40 to -100 degrees F, use two towers, each filled with desiccant material. While one tower adsorbs the moisture and dries the air, the second tower is regenerated. By alternating tower functions, desiccant dryers provide a constant stream of very dry air.
