Clean, Dry Air – Makes Your Operation More Productive

Compressing air creates heat and concentrates water and other contaminates. These must be removed for efficient use in an industrial compressed air system. Clean, dry air allows pneumatic instruments, valves, and controls to operate reliably, keeps pneumatic equipment running at peak efficiency, and extends the service life of air tools, motors, and cylinders. Dry air also helps ensure product and process quality.  


ATLAS COPCO FD Regrigerant Dryers
Incorporating unique, patented technological innovations and extra energy-saving options, Atlas Copco’s FD refrigerant dryers provide you with the clean, dry air you are in need of to expand the life of your equipment and ensure the quality of your end product.

ATLAS COPCO FX Regrigerant Dryers
The FX range of refrigerant dryers offer a reliable, cost effective and simple solution. To avoid condensation and therefore all chance of corrosion and damage, the compressed air needs to be dried, which is exactly what the FX units are designed to do. These simple reliable units remove water from the air and the risk from your system, ensuring that your money doesn’t just disappear into the air.

The What

The most common compressed air dryer technology is the refrigerated air dryer.  All air will contain some moisture content, and as you know from experience on a hot muggy day you can actually feel that higher than normal moisture content.  An air compressor will naturally transfer any and all moisture into your compressed air system.  This can be problematic for a number of reasons, particularly if you are in an industry that requires specific moisture content.  When an air dryer is either poorly sized or not functioning properly its ability to remove the moisture from the compressed air is compromised, and you may have more moisture being introduced than you should have or can allow based on your process.


The Why

A typical requirement is to reduce microorganism growth within a compressed air system.  With high levels of moisture a compressed air system can be an absolute breathing ground for all types of bacteria to grow.  These microorganism will of course be introduced into your work space/atmosphere as soon as compressed air is released, causing a potential health hazard in the workplace.  And in cases where aluminum piping is not used moisture will cause the compressed air piping to rust, this will provide an increased cost to your compressed air system by means of shrinking the internal diameter of your compressed air piping from the inside and compromising its ability to allow efficient compressed air flow.  This flow restriction will cause pressure drop which will result in additional energy demand at point of generation in order to adequately supply end use.  Both are examples that can be either mitigated or avoiding entirely through the use of a correctly sized air dryer which is able to effectively remove the required amount of moisture from your compressed air system.


Old air dryers may not be up to performance any more.  As refrigerated air dryers age they will of course require refrigeration service by means of refrigerant top off.  Your current air dryer may not actually be performing as expected, and the summer is the perfect time to check in and make sure that it can actually handle the demand.  CompreVac is also here to help in regards to service, feel free to call our service department should you need to have an air dryer looked at or evaluated as well.


The Solution

Atlas Copco has both a non-cycling series as well as a line of Smart cycling air dryer available, which are better able to help save energy and provide a faster return on investment when compared to traditional non-cycling technology.  The FD smart cycling series is able to achieve this by varying its working cycle to match your actual air drying demand.  This type of air dryer can provide you with confidence of knowing that you are not wasting unnecessary energy to dry your compressed air while also ensuring that your air dryer can match demand.
