Wherever you go in the world, whatever application you look at, you will find Atlas Copco dryers in silent operation around the clock. Industry leading companies invest in dry quality air,because they know it’s the best solution for a long term, trouble-free operation. Why shouldn’t you follow their example? No shop is too small, no air requirement too low to benefit from what FX dryers have to offer: simple and reliable operation, excellent pro-tection of your products and systems against damage or corrosion. Size doesn’t matter, results do.

Why invest in dry quality air?

Air treatment –a smart investment

When the air that surrounds us is compressed, its vapor and particle concentration increases dramatically. The compression process causes the oil and water vapors to condense into drop-lets, and then mix with the high concentration of particles. The resulting mixture is an abrasive oily sludge that in many cases is also acidic. Without air treatment equipment, much of this cor-rosive sludge will enter the compressed air system, corroding the pipe work, damaging pneumatic tools and equipment as well as potentially compromising final product quality.

The hidden danger of untreated air

Protect your pipes.Protect your production.Protect your reputation.

Good air quality saves money.The Atlas Copco FX dryer is the smart choice.

FX dryers – the smart choice

Poor air quality costs you money

If the corrosive sludge is allowed to enter the compressed air system, it will not be long before problems start. These are some of the most common, and most expensive:

Tools and equipment break down more regularly, experi-ence a shorter lifetime and reduced power. The end product, or other materials that come into contact with the contaminated air, can suffer spoilage and quality degradation.The compressed air pipe work will corrode, leading to leaks and a loss of valuable compressed air/energy.

As an example, a small leak of just 1/8 inch is roughly equivalent to wasting 3.7 kW of electricity. In a year, this would cost around

The benefits add up

Adding filtration to the installation will further increase the quality of the air. This results in even a lesser chance that tools and machines will be damaged or final product quality compromised.

No installation is complete without filtration

1 The prefilter will protect the dryer, and also remove free water, particles to 1 micron and oil to .1 ppm.

2 The final filter removes particles to 0.01 micron and oil to .01 ppm.

3 The final result is dry clean air, which allows you to concentrate on your business, without problems.

4 Fan control pressure switch(only FX13-15)

5 Condenser fan

6 CondenserCools the refrigerant slightly so that it changes from gas toliquid; refrigerant is more effective in the liquid state.

7 Capillary filterProtects the expansion device from harmful particles.

8 Capillary tubeReduces the refrigerant’s pressure, thereby lowering itstemperature and increasing its cooling capacity; the refrig-erant is now almost all liquid, with some residual gas.

9 Hot gass bypassRegulates the amount of refrigerant passing throughthe air-to-refrigerant heat exchanger, ensuring a stablepressure dewpoint, and eliminating the chance of thecondensate freezing.

Refrigerant circuit

10 Air inlet Hot saturated air enters the dryer and is cooled by the out going air via the air-to-air heat exchanger Reducing the temperature of the inlet air reduces the load on the refrigerant circuit.

11 Air-to-refrigerant heat exchanger Transfers heat from the compressed air to the cold

refrigerant, forcing water vapor in the compressed air to condense. The more effective the heat transfer, the cooler the air becomes and the more water vapor condenses.

12 Air/air heat exchanger

13 Water separatorCollects and drains off condensate from the cooled air

flow. The more efficient the separation, the better the pressure dewpoint. Droplets which are not collected revaporise and degrade the pressure dewpoint. The collected droplets are reliably evacuated from the separator through an electronic drain.

14 Automatic drainA

15 Air outlet Re-heats the outgoing air and prevents condensation on the factory’s pipework.
