MDX Refrigerant Type Dryers

The compressed air produced by the compressor contains a certain
amount of relative humidity that could still condense.

To eliminate the damage produced by condensate without wasting
compressed air, a series of MDX with ECD dryers has been developed
conforming with environmental needs to European standards.


On intake, the saturated compressed air undergoes an initial cooling in
the air-air exchanger by means of cold dried air. The second cooling
phase takes place inside the evaporator where the air reaches the
preset dew point. All the condensate separated during the cooling
phase is treated and discharged automatically by a system of level
sensors. The output compressed air is adequately dried and suitable for
the majority of industrial uses.

MARK is one of the world’s leading manufacturers of dryers and is the
only air compressor manufacturer that designs and produces all the
dyers they use for their range of compressors in their own factories.

Range: 12.4CFM – 2472CFM


No CFC = No impact on the ozone layer.

CDX 4 ÷ 18: R 134a

CDX 24 ÷ 700: R404A


No wasted of compressed air because of the intelligent automatic
discharge of condensate.

Discharges only water, NOT COMPRESSED AIR

Energy Saving
Noise-free, no acoustic impact.

Refrigerated Air Dryers

The need for compressed air with lower dew points with respect to drying or refrigeration
plants finds a response in adsorption drying systems. These systems primarily consist of
two (EEC standard) filters, each containing a charge of adsorbent material, an automatic
regulations system and, with pre and post filters.



Wet Air from the compressors passes through inlet filter (1) which removes
the oil and enters in to tower A.
The dessicant contained in it adsorbs the water vapour molecules. After a fixed (STD) or
variable time (CD) the way valve (2) deviates the airflow from tower A to tower B and it
the operation tower.


During the drying phase in the tower A, some dry air is deviated into the top of tower B,
extracting the trapped water vapour from the dessicant material.

During this phase, tower B is open to the atmosphere, allowing the purge air to expand.
The silencers (3) on the outlet ensure quiet operation PRESSURIZATION PHASE: Once
regeneration has taken place and tower B is pressurized, the way valve (2) changes air
flow again.

ADS 1–10 STD:

Compact and versatile Installation with multiport system. The inlet pre-filter is delivered
loose with the dryer but it can be directly fixed on ADS. The post-filter are integrated in the
dryer. Electronic Automatic Control(STD).

ADS 20–80 STD:

Floor mounted kit as standard. The inlet pre-filter and the outlet post-filter have to
mounted on air distribution line. Electronic Automatic Control (STD) as standard, control
dew point as option (CD).

ADS 110–215 STD:

Robust frame. Wide vessels for optimum air speed and reliable drying. The filters have to
be mounted on air distribution line. Control (STD) as standard, control dew point as option

Energy Saving Control Dew Point – a small investment.
The ES-CDP is an advanced control system that regulates the operating cycle of
adsorption air dryers. The system automatically lengthens and/or reduces the drying cycle
according to the delivery dew point temperature whilst other functions remain unchanged.
This reduces the average consumption of purified air and leads to a significant reduction
in-operating costs. The ES-CPD is available for the range of ADS 20÷215 dryers.
