Egypt has extreme heat during summer months with high humidity in the coastal areas reaching up to 85% - generally speaking, atmospheric air contains more water vapor at high temperatures and less at lower temperatures. This has a significant effect on the water concentration when the air is compressed. Problems and disturbances, such as pipe corrosion, can occur due to water precipitation in the pipes and connected equipment. To avoid this, the compressed air must be dried.
Moisture creation in a compressor is unavoidable, but if properly treated, it will prevent damage to pneumatic machinery, air motors, valves and any other components, as well as avoid possible contamination of the end products. In order to avoid unnecessary maintenance repairs and potential production shutdown, it is recommended to be proactive and properly implement the necessary steps to keep the compressed air dry, clean and suitable for your operations.

Pipe damage due to exessive water content
1. Causing rusting and wear of the interior part of the compressed air piping which leads to holes and accordingly air leakages which leads to pressure drop and accordingly loss of energy and Money!
2. Can adversely affect the color, adherence, and finish of paint applied by compressed air
3. Can jeopardize process industries where many operations are dependent upon the proper functioning of pneumatic controls. The malfunctioning of these controls due to rust, scale, and clogged orifices can result in damage to product or in costly shutdowns 4. Can freeze in control lines in cold weather, which may cause faulty operation of controls
5. Causes corrosion of air or gas operated instruments, giving false readings, interrupting or shutting down plant processes.
6. Finally if the air is in contact with your End Product can leads to Rejection of your product and affects your profitability. That’s why, to avoid disturbances and disruptions due to water and humidity in the pipes, compressed air must be dried with after-coolers and drying equipment.
Before looking at the several types of dryers available, you need to look at what to consider in deciding which dryer is best for the specific requirements and suits the environment in Egypt.
Selecting the proper dryer to treat wet compressed air in Egypt depends on the specific requirements and moisture tolerance levels of the machines that utilize compressed air.
Most industrial and manufacturing facilities can achieve such requirements with a refrigerated air dryer, while spray paint operations, laboratories and certain printing and pneumatic tool users require a desiccant dryer to supply critically dry air.
There are a number of ways to dry compressed air, most of them are listed below. For more on how to choose the right dryer for your application

If your application is one from the illusterated below with photos- then Our Refrigerated dryers is the best choice for you.
The air that leaves a compressor reaches 100% humidity. Aftercoolers and drains are the first line of defense against water in your system. Our Refrigerated dryers eliminate the residual humidity to achieve absolutely dry air for applications that require advanced air quality
Dry and clean compressed air, produced reliably and efficiently, is essential for a broad range of industrial applications.
A dry compressed air system is essential to maintain the reliability of production processes and the quality of end products. Untreated air can cause corrosion in pipe work, premature failure of pneumatic equipment, and product spoilage. Atlas Copco's desiccant dryers protect your systems and processes by producing superior dry compressed air in a reliable and energy-efficient way.
The biggest deciding factor when it comes to compressed air dryers is the need or desired dew point. As previously learned, refrigerated air dryers are capable of providing dew point of 3-5 °Celsius (37-41 °Fahrenheit), which is sufficient for most applications. However, if a process requires compressed air of higher quality, a desiccant dryer would need to be introduced into the system. Regenerative desiccant dryers are capable of achieving up to -70 °C (-100 °F) as standard, providing your compressed air system with clean and dry air. Unlike refrigerated air dryers, regenerative desiccant dryers utilize desiccant beads that adsorb the water vapors out of the compressed air. During the adsorption process, water vapors adhere to the desiccant bead without changing the composition of the desiccant. Once the desiccant beads get saturated with moisture, a process of regeneration occurs via dry purge air, heat or combination of both application to dry the wet desiccant. This type of a desiccant dryer typically uses a twin tower construction design, in which one tower dries the wet air, while the other tower regenerates and purges the moisture out of the desiccant beads.
