Can Your Compressed Air Dryer Cope This Summer?


Overheated System = Production Down Time


Like us, your compressed air system can sweat in the warmer months! Air Dryers can act like an air conditioner to your airline; eliminating condensation due to humidity, and therefore preventing damage to your expensive equipment.


As the months get hotter some compressed air dryers don’t function as well leaving unwanted residual moister. Excessive water in compressed air, in either the liquid or vapour phase, can cause a variety of operational problems for users of compressed air. These include freezing of outdoor air lines, corrosion in piping and equipment, malfunctioning of pneumatic process control instruments, fouling of processes and products, and more.


If your compressed air dryer is overheating this summer consider the following questions and contact Nessco Pressure Systems.


1. Is your dryer the right size/design for your application and conditions?

When selecting the correct dryer you must consider the level of moisture required to be removed from the compressed air for that specific application. If your dryer is not sized correctly for a particular system then issues such as overheating, decreased efficiency and shut-down can result.


2. Is your dryer in the correct location?

The performance of the dryer will improve if installed in a cooler well ventilated station.


3. Do you have the correct Filtration?

Filters work with compressed air dryers to remove water and other contaminants from the compressed air and prevent component contamination. Three types of filters are typically used; Particulate, Coalescing and Absorption.


4. Is your compressed air system and dryer properly maintained?

Keeping your equipment and machinery running at a consistent high level of performance is important to every industry; breakdown of vital machinery in the workplace equals lost time and money. Air dryers and filters keep your compressed air system operating efficiently, but only if they are properly maintained.

Why Your System Needs A Compressed Air Dryer

A Compressed Air Dryer is used for removing water vapour from compressed air.


Humidity is a component of atmospheric air, which can be found in the form of condensate and/or vapour in compressed air distribution systems and the machines that use the compressed air.


If the condensate can be easily separated and discharged, humidity, in the form of vapour, will follow the compressed air flow all the way to the final product. When it then cools, a part of this humidity present in the compressed air condenses and over time causes serious damage to the distribution network, the machines using the compressed air and the final product.



How Air Dryers Work


For example, 5.1 l/h of condensate is separated from a compressor with an output capacity of 10 Nm3/min and an ambient intake air temperature of 20°C and 70% relative humidity, whilst operating at a delivery pressure of 8 bar (g) and cooling the air to 30°C.



If the compressed air is then dried even more to a dewpoint of +3°C, a further 1.7 l/h of condensate can be separated.
