  • WHY DRY AIR ?

    The air given off by any compressor always contains water

    vapour, the amount of which depends on the temperature and

    the relative degree of humidity.

    When the air is compressed, the volume decreases

    proportionately, but the exhaust water vapour still remains in

    the air. When temperature deceases and reaches a value at

    which the air becomes saturated, the water vapour in the air

    begins to condense. This is called DEW POINT. With an

    appropriate aftercooling unit which reduces the temperature of

    the air produced by the compressor, approximately 60 70% of

    the water gets condensed.

    FUNCTIONING PRINCIPLE

    The UE / UR series dryers are basically made of two different circuits a

    compressed air circuit, divided into two heat exchangers and a

    refrigerating circuit. The hot and humid inlet compressed air passes

    through the air air heat exchanger and then reaches the evaporator

    (airfreon heat exchanger), where it is cooled by the refrigerating

    circuit until it reaches the preset dew point, thus condensing the

    moisture it contains. In the separator the condensed moisture is then

    separated and removed.

    The advantages of such a system are essentially two, first of all the inlet

    air is precooled, so the refrigerating system can be sized in order to

    guarantee a more limited thermal jump, with an energy saving of about

    4050%, and secondly no cold air is conveyed through the compressed

    air line, thus preventing the overall formation of condensate on the

    external surface of the piping.

    DAMAGES CAUSED BY THE CONDENSATE

    Condensate corrodes piping, solenoid valve

    and pneumatic tooling, forcing the user to

    withstand expensive repair interventions,

    especially the expensive downtime heavy

    Costs which Cannot be easily controlled.

    When compressed air is used as process air

    for paint ing equipment, in chemical

    industries, food processing industries, glass

    factories and in plants for conveying and

    handling hygroscopic raw materials, the

    installation of ultrafilter dryer is essential to

    eliminate the condensate which pollutes the

    production cycle.

    FEATURES

    Noncyclic operation

    Constant Pressure Dew Point 3C

    Hot gas bypass valve for freeze protection

    High efficiency centrifugal moisture separator with timer controlled electronic auto drain to remove condensate

    Easy to install, operate and maintain

    Low noise

    Low power consumption

    Low maintenance costs

    In addition to the above ultrafilter India also supplies controller with multiple temperature displays and controllers upon request, for dryer models UE/UR 1000 & Above.

    For an optimal operation of its dryers, ultrafilter (india)

    provide reliable and stateoftheart microprocessor

    based controllers to monitor and control the operation of

    the dryers.

    ELECTRONIC CONTROLS

    Following are the different functions of the dryer controllers:

    Display of dew point temperature

    Operation of hot gas bypass valve

    Operation of condensate drain valve

    URD2 Controller also controls the operation of condenser fan motor
