Heatless Desicant Air Dryer - KTA Series
Brand: Zander
Parker Zander KTA Series heatless desiccant air dryers remove water vapor from compressed air through process known as Pressure Swing Adsorption.
A pressure dewpoint of -40°F (-40°C) is 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 separate but identical pressure vessels commonly referred to as “dual” or “twin” towers.
As the saturated compressed air flows up through the “on line” tower, its moisture content adheres to the surface of the desiccant.
The dry compressed air is then discharged from the chamber into the distribution system.
A solid state controller automatically cycles the flow of compressed air between the towers, while the “on line” tower is drying, the “off line” tower is regenerating.
Regeneration, sometimes referred to as purging, is the process by which moisture accumulated during the “on line” cycle is stripped away during the “off line” cycle.
As low pressure dry purge air flows gently through the regenerating bed, it attracts the moisture that had accumulated on the surface of the desiccant during the drying cycle and exhausts it to the atmosphere.
To protect the desiccant bed from excess liquid, all Parker Zander KTA Series Heatless Air Dryers are designed to work with the natural pull of gravity.
By directing the saturated air into the bottom of the “on line” tower and flowing up through the bed, liquid condensate caused by system upset, is kept away from the desiccant and remains at the bottom of the tower where it can be easily exhausted during the regeneration cycle.
Counter flow purging ensures optimum performance by keeping the driest desiccant at the discharge end of the dryer.
Moisture load, velocity, cycle time, and contact time determine tower size and the amount of desiccant.
To ensure design dewpoint, each tower is carefully sized to allow a minimum of 5.5 seconds of contact.
To prevent desiccant dusting and bed fluidization, air flow velocities are kept below 50 feet per minute.
The dryer can cycle for years without changing the desiccant.
Heatless dryers in general are the most reliable and least expensive of all desiccant type dryers.
Parker Zander KTA Series Heatless Desiccant Air Dryers are the most energy efficient thanks to standard features like, “Variable Cycle control”, compressor inter-lock and purge flow regulator.
