A compressor that operates in an ambient

temperature of 20°C and 70% relative
humidity, takes in 12 gr of water for every
Nm3 of air.

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.

Filtered compressed air is no longer sufficient. Modern industries
require compressed air that is increasingly filtered with low dew
point and condensate.

Maintaining the correct dew point for compressed air ensures

correct operation throughout the production process.

MARK has over 30 years’ experience in drying compressed air, and

offers the optimum solution to satisfy any demand.

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:
*FPRE
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.
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
the operative tower. P max P max

A B
Regeneration phase:
atm. atm.

During the drying phase in the tower A, some dry air is

deviated into the top of tower B, extracting the trapped
1
water vapor from the desiccant material. During this
phase, tower B is open to the atmosphere, allowing the 2
purge air to expand. **FMO FMM
The silencers 3 on the outlet ensure quiet operation.

Pressurization phase:
Once regeneration has taken place and tower B is Adsorbent material

pressurized, the 3 way valve 2 changes air flow again.

STD: electronic timer control
CD: control dew point
Developed with high quality components,
ADS 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 models
(ADS/STD).
There is also control dew point
version (ADS/CD) where the drying
phase is dew point dependent and is
controlled by our electronic dew point
management system.
The two inlet prefilters FMO-FMM and the
outlet postfilter FPRE have to be mounted
on the air distribution line. The filters are
ADS/STD included but not pre-mounted.

 CONTROL DEW POINT - CD
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.
