Adsorption Air Dryer

As quality air from an oil-free air compressor is the
requirement for your application,dry air is equally desirable.
Air dryers are designed for offering dry air.For a quality
end product and reliable production process,DeWATE
offers the unique range of adsorption air dryer.The
heatless adsorption air dryer is energy-saving,compact,
lightweight,easy to install,and steady-function.Due to
its limitation on the water-elimination principle, it is
commonly used as the pre-processor of the regeneration
dryer.The desiccant can adsorb the water in the
compressed air selectively,which principle the regeneration
dryer used;thus,to dry the compressed air,compared with
the refrigeration compressed air dryer of ideal pressure
dew point -2°C~-10°C,the heatless adsorption air dryer
can reach the pressure dew point of -20°C~-40°C and
even -70°C if specially designed.The DeWATE series
heatless adsorption air dryer has a twin-tower structure,
and offers steady function,cost-saving and easy installation.

  • Quality Guarantee
  • 1: Strictly designed and tested according to the industry
    standard and ISO9001-2000 and CE system.
  • 2: Protection measurements in design
    Patent design of the regeneration tower: It adopts the
    reasonable air flow distribution and those support small
    balls to guarantee a steady outlet dew point.
    Good-quality pneumatic valve/butter fly valve and control
    valve are used to ensure the steady and reliable performance.
    The reasonable structure is designed to lessen the pressure
    drop and save the cost
    The advanced and thorough control measurement can
    guarantee the steady outlet dew point and also can save
    the total energy-cost
  • 3:Promise on production and test
    The working flow quality
    and the product quality of the adsorption air dryer are
    strictly controlled.
