Compressed Air - The 4th Utility Compressed air is a safe and reliable power source that is widely used throughout industry. Approximately 90% of all companies use compressed air in some aspect of their operations, however unlike gas, water and electricity, compressed air is generated on-site, giving the user responsibility for air quality and operational costs. Without proper treatment, compressed air systems suffer from performance and reliability issues. Almost all of these issues can be directly attributed to contamination, the main sources of which are: Water Vapor Condensed Water...

What is adsorption drying? Drying compressed air through adsorption represents a purely physical process in which water vapor (adsorbate) is bound to the drying medium (adsorbent) through binding forces of molecular adhesion. Adsorbents are solids in spherical and granular form which are permeated by an array of pores. The water vapor is deposited onto the internal and external surface of the adsorption medium, without the formation of chemical compounds taking place, therefore the adsorption medium does not have to be replenished but only periodically regenerated. Heatless The layout of...

Behind the scenes of a DTA Series Heatless Adsorption Dryer domnick hunter DTA Series Heatless Adsorption Dryers remove water vapor from compressed air through a process known as Pressure Swing Adsorption (PSA). Pressure dewpoints ranging from -40°F to -100°F are attained by directing the flow of saturated compressed air over a bed of desiccant. The most commonly used desiccant is activated alumina, a spherical shaped, hygroscopic material, selected for its consistent size, shape and extreme surface to mass ratio. This physically tough and chemically inert material is contained in two...

Operational status Sequence annunciator domnick hunter’s sequence annunciator is a solid state visual display panel that shows exactly what is happening in the dryer. The panel lights signal which tower is “on-line” drying, and whether the “off-line” tower is purging, repressurizing or in Dewpoint Dependent Switching (DDS) mode. It will also annunciate optional equipment operation and function alarms. The panel is integral with the NEMA 4X Master Control and is conveniently mounted for easy monitoring. Variable cycle control Additional energy savings can be achieved by adjusting the amount...

An overview The adsorption capacity of the desiccant within the dryer is essentially constant whereas the moisture loading and the air flow through the dryer are continuously varying as ambient and plant conditions change. In order to maintain the specified air quality downstream of the dryer, it has to be sized for the worst case conditions, namely the lowest pressure, highest flow and highest inlet t e m p e r a t u r e . These conditions may only occur for a small part of the service life of the dryer, for example, the highest inlet temperatures may only be present during the summer...
