ZMA Modular Heatless Desiccant Dryers use desiccant media in a twin-column design and a process of heatless desiccant regeneration to make available very dry air for critical applications Proprietary shuttle valves alternate flow between the two columns for simultaneous drying and desiccant regeneration delivering a continuous supply of dry Mar 01 2018There are four different ways to regenerate the desiccant material and the method used determines the type of adsorption dryer Here are the four types of adsorption dryers: Heatless-type dryers These dryers are best suited for smaller air flow rates high

Heatless Compressed Air Desiccant Dryer Calculation

The stored heat of adsorption is consumed during the regeneration process to remove moisture from the desiccant to provide continuous service If the heat is lost prematurely such as by excessive flow rates the heatless dryer cannot regenerate and the system fails requiring priming at minimal flow for an extended period of time before continuing

Adsorption Dryers A18TXA - A157TXA with activated carbon stage Adsorption dryers of the Series A_TXA as unit with activated carbon stage constitute a reliable purification unit which meets extreme requirements when the compressed air must not only be dried but also be odourless and free from oil † Heatless Regeneration-Pressure-Swing Adsorption

Purge regenerated adsorption dryers (heatless-type dryers) These dryers are best suited for smaller air flow rates The regeneration process takes place with the help of expanded compressed air (purged) and requires approx 15–20% of the dryer's nominal capacity at 7 bar(e) working pressure

Jul 23 2020The desiccant used most often in the heatless regenerative air dryer is activated alumina It is the desiccant of choice due to the following reasons: 1 Economical 2 High affinity for water 3 High abrasion resistance 4 Good adsorptive capacity (at higher RH) 5 High crush strength 6 Resistance to degradation by liquid water

Kaeser Adsorptive Desiccant dryers (KAD Series) employ a heatless regenerative design to produce pressure dew points as low as -100F Solid-state controls with adjustable cycle timers allow KAD Series dryers to be easily adapted to user requirements

Heatless regenerated desiccant dryers from 1 17 to 154 53

Desiccant dryers from the DC 12 model and higher feature extremely low regeneration air requirements – thanks to optimal flow dynamics through the high-quality desiccant Moreover the resulting heat from the adsorption process is channelled into the regeneration process Energy-saving intelligent control:

Heatless-regenerated Adsorption Dryers Rev 01_0520 adsorption regeneration and pressure build-up) requires less regeneration energy than dryers with shorter cycles and protects the adsorbents due to the lower number of load cycles The possibility of individual time setting creates further desiccant vessel adsorption phase

The HLP Series of high-pressure heatless adsorption dryers is a complete purification package and includes high efficiency pre?filter and after-filter as well as a condensate drain The Ultrapac™ Smart heatless regenerated adsorption dryer is equipped with a

46 6 cfm heatless regenerative desiccant air dryer for pneumatic automation system Adsorption takes place under pressure in first column while second column regenerates with a portion of already dried compressed air at ambient pressure A dryer consists of two columns filled with desiccant beads controller with LCD dicplay valves

Kaeser Heatless Desiccant Dryers (KAD) (Table 1) Note 1: KAD dryer inlet flow capacities are established in accordance with CAGI (Compressed Air and Gas Institute) Standard ADF-200: Inlet air pressure 100 psig inlet air temperature 100F saturated Note 2: The purge flow rate of any pressure swing (heatless) desiccant dryer is not constant throughout the purge cycle

The desiccant used in adsorption dryers binds water molecules and completely separates the moisture from the compressed air Pressure dew-points down to -70C can be achieved by using adsorption dryers Adsorption dryers are suitable for continuous operation and are available for all volume flow and pressure ranges

GDX series of heatless regenerative dryers

The Gardner Denver GDX series of heatless regenerative dryers are the ideal solution for many thousands of compressed air users worldwide in a wide variety of industries Compressed air purification equipment must deliver uncompromising performance and reliability whilst providing the right balance of air quality with the lowest cost of operation

Beneficially a pressure dew point of -15F (-26C) or better will not only prevent corrosion but will also inhibit microorganisms within the compressed air system Heatless adsorption or desiccant dryers remove moisture by passing air over a regenerative adsorbent material

The desiccant used in adsorption dryers binds water molecules and completely separates the moisture from the compressed air Pressure dew-points down to -70C can be achieved by using adsorption dryers Adsorption dryers are suitable for continuous operation and are available for all volume flow and pressure ranges

This is made possible with an adsorption dryer with a pressure dew point of -40C (-70C optional) Take advantage of BOGE's DAZ Series heatless adsorption dryer which regenerates a partial stream of dry compressed air parallel to the adsorption of the desiccant Product Adsorption dryers heatless regeneration
