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
(air‐freon 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 pre‐cooled, so the refrigerating system can be sized in order to
guarantee a more limited thermal jump, with an energy saving of about
40‐50%, 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 “down‐time”‐ 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
Non‐cyclic operation
Constant Pressure Dew Point 3°C
Hot gas by‐pass valve for freeze protection
High efficiency centrifugal moisture separator with timer controlled electronic auto drain to remove condensate

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 state‐of‐the‐art 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
