CONDENSATE DRAIN

Compressed air is cooled at 30°C and condensed water vapour is separated, while 2.8 gr of water for every Nm3 of air
that condense can remain in the air (compressed at 10 bar as in the example) in vapour form.

In the event of particularly rapid expansion and/or particular ambient conditions, compressed air for the application may
be cooled to such an extent that the temperature drops below its dew point.

If the temperature falls below its dew point (*), further condensation takes place resulting in separation of humidity and
formation of condensate.
(*) The Dew Point is the value of the temperature when we have the max. water vapour concentration in the air, at one specific pressure.

Over time, this may lead to:

- serious damage to the distribution network, the machines using the compressed air and the final product.
- plugs of ice forming in the tubing in certain situations.

The cooling process does not allow the temperature to fall below 0°C (solidification of water).
However, specific applications or particular ambient conditions require dew point temperatures of below 0°C.

Only adsorption dryers can achieve this, because condensate separation takes place WITHOUT lowering the
temperature of the compressed air or gas.

Principle
Drying phase:
Wet air from the compressors passes
through inlet filter 1 which removes the
oil and enters in to tower A.
The desiccant contained in it adsorbs
the water vapor molecules. *APF
After a fixed (STD) or variable time (CD)
the 3 way valve 2 deviates the airflow
from tower A to tower B and it becomes

HAD 650-1300 STD: electronic timer control - CD: control dew point
Developed with high quality components, HAD dryers guarantee a stable dew point of -40°C. The use of an optimized desiccant
volume and a wide vessel, ensure a low air speed and a longer contact time.

Purge phases are controlled by an electronic timer on the standard (HAD/STD). There is also control dew point phase is dew point

How to decrease your consumption?

The electronic Pressure Dew Point control (CD) extends the
drying phase of the dryer’s cycle. It is done by measuring
PDP of compressed air on the dryer outlet and only switching
the columns when desiccant in the active tower is saturated.
The regeneration part of the cycle stays fixed.
As most of the time compressor and dryer runs < 100% load,
this results in a significant extension of the drying time and a
reduction in purge air consumption.
Typically the extra investment in a Pressure Dew Point control
is paid back in a few months by savings made on dryer
running costs.
