HBP Series - Blower Purge Regenerative Desiccant Dryer
Class 2 (-40°F/-40°C) Dew Point Performance
HBP Series blower purge regenerative dryers are economical & reliable
HBP 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/-40°C) dew point performance
is guaranteed. HBP 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. These 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).
