The
domnick hunter
range of desiccant air dryers is designed to remove moisture from compressed air by utilising
the most up to date technology to achieve pressure dewpoints of -40°C and by appropriate flow de-rating, -70°C.
The Desiccant Air Dryers comprise of aluminium columns each containing twin chambers filled with desiccant material
which dries the compressed air as it passes through. One chamber is operational (drying), whilst the opposite
chamber is regenerating by either Pressure Swing Adsorption (PSA) or Thermal Swing Adsorption (TSA) depending
upon the model.
PRESSURE SWING ADSORPTION (PSA) - HEATLESS DX MODELS
A small amount of the dried compressed air is used to regenerate the saturated desiccant bed by expanding dried air
from line pressure to atmospheric pressure, "stripping off" the moisture adsorbed by the desiccant material, and
therefore effecting regeneration.
THERMAL SWING ADSORPTION (TSA) - HEAT REGENERATIVE DH MODELS
Regeneration of the saturated desiccant bed is achieved by using a combination of heat and a smaller amount of
dried compressed air than used with the PSA technique. By contacting the desiccant with the heated purge air, the
moisture evaporates, thus regenerating the desiccant bed.
MODULAR CONSTRUCTION
By simply adding further modules (banks) of PNEUDRI , the operational capacity of the dryer can be increased to
precisely match any system demand. Addition of further dryer banks also allows the dryer capacity to be extended to
cater for any plant expansion, or a standby capacity.
PNEUDRI haS been designed to make maintenance requirements minimal, and because of its compact size, can be
installed virtually anywhere within a factory.
