ACCD Series

ALMiG ACCD Series dryers protect air systems exposed to temperatures below freezing, produces low pressure dew points and supplies the ultra-dry air that is necessary for your most critical applications. Minimum purge air usage saves the heat of adsorption, maximizing the moisture holding capacity of the purge air which minimizes the amount required. Standard 10 minute cycle gives increased desiccant life over units operating on shorter cycles. ACCD Series dryers allow the off-stream tower to fully repressurize before going on-stream preventing bed movement and loss of pressure downstream.

AWDB Series

AWDB Series dryers improve air system efficiency by the use of a dedicated axial blower, instead of a percentage of dehydrated purge air, to regenerate the off-line desiccant tower. ISO 8573.1 Class 2 (-40°F) dew point performance is guaranteed. AWDB Series compressed air dryers will produce the design dew point while operating continuously at maximum rated flow (100% duty cycle) at CAGI ADF 200 inlet standards of 100°F inlet temperature and 100% relative humidity at 100 psig.

Blower purge type regenerative compressed air dryers are an economical and reliable way to dry compressed air to dew points below the freezing point of water. Desiccant dryers lower the dew point of compressed air by adsorbing the water vapor present in the compressed air onto the surface of the desiccant. Adsorption continues until equilibrium is reached between the partial pressure of the water vapor in the air and that on the surface of the desiccant. AWDB dryers continuously process compressed air by using two identical towers, each containing a desiccant bed. While one tower is on-stream drying, the other tower is off-stream being regenerated (reactivated, i.e. dried out). The towers are alternated on- and off-stream so that dry desiccant is always in contact with the wet compressed air. In this way a continuous supply of dry air down stream of the dryer is possible. The switching from one tower to the other is controlled by a solid-state controller on either a fixed time basis (standard) or a demand basis (optional).

AWD Series

AWD Series dryers will produce the design dew point while operating continuously at maximum rated flow (100% duty cycle) at CAGI ADF 200 inlet standards of 100°F inlet temperature and 100% relative humidity at 100 psig.

Standard AWD Series (Heated Purge Desiccant) Compressed Air Dryers: -4°F to -40°F Pressure Dew Points

The standard design delivers ISO 8573.1 dew points between Class 2 and Class 3 automatically. Class 2 (–40°F) dew points protect against freezing during low ambient conditions and Class 3 (–4°F) dew points keep your air system bone dry during the heat of summer.

An AWD Series dryer with an EMS package may enable the use of a smaller air compressor. Total system efficiency would then be superior due to the linear energy-saving potential of the dryer.

ACDS, ACDL & ACDE Series

Heatless Regenerative Desiccant Dryers

Since 1923, sensitive applications requiring clean, dry, compressed air have turned to ALMiG for the optimal solution. Utilizing twin towers filled with premium grade activated alumina, ALMiG Heatless dryers are available with 3 application specific control systems to meet the needs of industry with economy and performance. ALMiG ACDL, ACDS or ACDE Series heatless desiccant dryers provide consistent outlet pressure dew points to -100°F (73°C).

Microelectronics, food packaging, paper, glass, pharmaceutical, powder painting, hospital laboratories represent a small sample of industries that use desiccant dryers.
