Atlas Copco Air Dryers

FD refrigeration air dryer series - 60 Hz

QUALITYDRY AIR

YYYYYour manufacturing operation

needs quality dry air to help avoid the

risk of product contamination and to

eliminate damage to the compressed

air system.

WWWWWith the introduction of the latest

Atlas Copco high performance FD

refrigerant dryers, you can be assured

of quality dry air at all times. Further-

more, the advanced technology of the

units with R134a and R404A refriger-

ants ensures they are environmentally

friendly and that they meet all the

current and future international

environmental regulations.

The problem

CCCCCompressed air entering the

airnet is always 100% saturated with

water vapour. When cooling down,

this moisture will condense, causing

damage not only to your compressed

air system, but also to your finished

products.

Without a dryer 90 l of water will enter your air system on an averageday. An Atlas Copco FD dryer removes virtually all of the moisturebefore it reaches your air system.

A typical example

Moisture can seriously harm

your compressed air system...

OOOOOn an average day, with ambient

air at 25°C and relative humidity at

70%, a compressor rated at 200 l/s

will take in about 280 l of water per

day in vapour form alongside the air.

AAAAAfter compression and cooling

the vapour turns to liquid, which will

harm your system if not removed.

Although the aftercooler eliminates

about two-thirds of the moisture

(approximately 190 l), the remaining

one-third flows freely through your

system, still capable of causing severe

damage to the system. The end result

could be high maintenance and repair

costs, as well as spoiled product.

... unless you install

an FD dryer

TTTTTo eliminate the problems caused

by moisture carryover, Atlas Copco

offers a comprehensive new range of

FD refrigerant dryers to precisely

match your installation.

DDDDDry compressed air keeps pneu-

matic systems running smoothly and

production lines rolling. It eliminates

the need for elaborate separator, filter

and condensate drain systems. Dry air

from the FD dryer prevents leaks and

pressure drops due to corrosion, saves

on maintenance and repair costs,

increases the overall efficiency of your

compressed air system and is your

guarantee of manufacturing a quality

end product.

Air circuitAir circuitAir circuitAir circuitAir circuitIncoming compressed air (AAAAA) is precooled in the air-to-air heat

exchanger (BBBBB), passes through the air-to-refrigerant heat exchanger (CCCCC)where it's cooled down to +4°C. The condensate is separated from theair and automatically drained by the water separator (DDDDD). Beforeleaving (EEEEE) the cold dry air passes for a second time through the air-to-air heat exchanger to be reheated.

Refrigerant circuitRefrigerant circuitRefrigerant circuitRefrigerant circuitRefrigerant circuitFrom the compressor (FFFFF) the refrigerant gas comes in the

condenser (GGGGG) where it is cooled by a high volume cooling fan / orcooling water and becomes liquid. A capillary tube or a pressureregulated expansion valve (HHHHH) regulates the flow into the air-to-refrigerant heat exchanger (CCCCC) where the refrigerant evaporates byextracting heat from the compressed air. The refrigerant pressure is thenincreased in the compressor and the cycle starts again.

Obtain the correction factors from the tables:K1 = 1.11 / K2 = 1.15 / K3 = 1.02 / Qnominal for FD40-60Hz = 50 l/s at reference conditions

Qactual = K1 x K2 x K3 x Qnominal
