Why
Compressed Air Purification? |
|
|
|
In
most manufacturing and service industries compressed air is an absolute
essential utility and
process medium. The compressor draws in ambient air, which is contaminated
with pollutants, particles and water, At compression stage contaminated
air is in addition exposed to high temperature and subsequent thermal
reactions. The compressed air leaving a compressor contains considerable
quantities of water vapour, oil and dirt-supplied untreated into
the distribution lines. The moisture would condense to liquid water
as it cooled, causing corrosion and considerable damage to the equipment
using the air. |

HEATLESS
DRYERS |
|
|
|
Features
and Benefits: |
|
 |
Compact,
occupies very less floor area. |
|
|
|
The
Electronic Control logic, Prefilter, Microfilter, Dryer, Dust
Filter(After filter) and silencers are supplied as a complete
package. |
|
|
|
Moisture
Separators (water Separator) also supplied for higher flow rates. |
|
|
|
Ready
to use and only to be connected to the compressed air line and
operates automatically. |
|
|
|
Heatless
method-self regenerative (by recycling of small supply of
the dry air stream through
the adsorption bed), most reliable drying method. |
|
|
|
Can
be adjusted to suit the particular operating conditions, therefore
running costs are saved. |
|
|
|
Can
be custom built, externally protected versions (closed type)
available on request. |
|
|
|
Complete
package serves easy installation, service friendly and safety. |
|
|
|
Constant
pressure dew point ranging from - 20 °C to - 70 °C is
achieved as per requirement. |
|
|
|
The
mixed bed system of dessiccant medium ensures a high level of
water adsorption, hence a long service life and continuous reliablity
are guaranteed. |
|
|
|
In
accordance with ISO/PNEUROP recommendation the dryer achieves
a compressed air quality of Class 2,1 & 1+ as per customer
requirement. |
|
|
|
Dryers
with pressure dew point of - 20 °C are distinguished by
very low requirements of regeneation air, thus low operating
cost. |
|
|
|

Pure
and dry compressed air is absolutely essential for the following areas
of application: |

Functioning
principle of the dryer: |
|
|
|
The
dryers of the PRD series are basically made by two different circuits.
A compressed air circuit,divided into two heat exchangers and a
refrigerating circuit. The hot and humid input compressed air passes
through the air-air exchanger and then reaches the evaporator (air-freon
exchanger), where it is cooled by the refrigerating circuit until
it reaches the present dew point, thus condensing the humidity it
contains. In the moisture separator the condensed humidity is then
separated and removed by auto drain. |
|
|
|
The
advantages of such a system are essentialy two, first of all the
air input 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 overall the formation of
condensate on the external surface of the piping. |
