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

Easy to install, operate and maintain

Low noise

Low power consumption

Low maintenance costs

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
