Why compressed air needs to be dried?

Compressed air contains 100% relative humidity of water, with its cooling in the pipeline, water will precipitate out, in the compressed air system, if there is water, will bring many disadvantages to the user.

Firstly, there will be an increase in running and maintenance costs, i.e. a rise in maintenance costs for components such as meters, solenoid valves, cylinders, etc.; a reduction in the efficiency of the equipment and the possibility of production interruptions;

Secondly, the social security investment of the whole production line increases, and it is necessary to add condensation, separation, sewage and other equipment in the system;

Lastly, the quality of the process will be affected by the high water content of the compressed air, thus affecting the quality of the product, especially for the paint spraying, sand blasting, pneumatic control systems, food processing, pharmaceutical and other industries.

The degree of dryness of compressed air is usually expressed by the dew point temperature, the dew point is the temperature at which water vapour starts to condense through cooling and becomes liquid from vapour.

Micro-heat regeneration adsorption dryer is on the basis of non-heat adsorption machine, adding a heater, which is used to regenerate the airflow to heat and regenerate the desiccant after elevating the temperature, which can improve the effect of regeneration and reduce the consumption of regenerated air to achieve the purpose of energy saving.
