Definition: Refrigeration & Air Dryers
Whenever compressed air is used, a compressed air dryer is required. Air dryers extract the humidity from air with different procedures. Without them, pieces and machines would rust and wear out quicker. The most common kind of air dryer is the refrigeration dryer: it contains liquid refrigerant, different kinds of heat exchangers and it stands out for its high dehumidification capacity. In addition to this there are further compressed air drying methods, like for example membrane and absorption dryers. At Surplex you will find used air dryers from leading manufacturers such as KAESER, BOGE and ECODRY.

Everywhere where compressed air is used, an air dryer
is necessary. These machines remove humidity from the air using particular processes. This is important because workpieces or machines could quickly rust, if the humidity stays high. Additionally, turbines from air-powered tools can be worn out very quickly without sufficiently conditioned air. Compressed air tubes in factory workshops are at risk of frost and therefore, the humidity in these areas needs to be removed. An air dryer
should only remove the humidity from the air; the oil and oxygen content of the air should remain the same.

- Removes humidity
- Used to provide protection against rust, frost and general wear
Personalized There are a variety of principles to which these machines work such as membrane dryers, absorption dryer
in cool and warm regenerating processes and the refrigeration dryer as a low temperature refrigeration dryer are common. The function of the most commonly used refrigeration dryer
is divided into different forms: plate fin heat exchanger; shell and tube heat exchangers; and plate heat exchangers. A condensate separator divides the condensate from the compressed air and removes it
With the application of condensed air in mechanical engineering it became necessary to remove the humidity from the air. Therefore, solutions were developed that could also dry a large amount of air in industrial settings. There are central air treatment systems and systems that can be directly attached to machines. Using this type of system, highly sensitive machines that are operated using compressed air receive purified, dried and partially lubricated air. These systems are mainly used in workshops, that undertake cutting processes and in the steel industry.
Several companies have specialised in the manufacturing of air dryers
. Some of the most recommended suppliers include KAESER, BEKO, BOGE and ECODRY.
