Refrigerated dryers are equipment used to remove 99% of the compressed air in air compressor systems. In industries where electronics, painting, plastics, and other gases are more stringent, its presence is common. However, for some gas-intensive industries, such as pharmaceutical factories, refrigeration dryers alone cannot sometimes guarantee the quality of compressed air. We will configure adsorption dryers. So how do you determine if an adsorption dryer is needed? Can adsorption dryers be used alone? What is the difference between adsorption dryer and refrigeration type?
The effective air supply of a refrigerated dryer can reach 100%. However, due to the restriction of the working principle, the dew point of the air supply for the refrigerating dryer can only reach a minimum of 3°C (pressure dew point), and it is subject to the intake air temperature. The effect is very large. For every 5°C increase in the inlet air temperature, the cooling efficiency will drop by 30%, and the dew point of the gas supply will increase significantly. At the same time, refrigeration dryers must consume a certain amount of electrical energy and cooling water. Adsorption dryers have a dew point of minus 60°C to below 70°C and can use adsorbent dryers to absorb water vapor to a greater extent. General engineers do not recommend the use of adsorption dryers alone. Adsorption dryers are used alone to increase work load and reduce dryer life. So what industry needs to use adsorption dryer? Food, beverage, pharmaceutical and other industries are often used.
Buying dryers is a very serious issue. Incorrect selection will have a negative impact on product production and increase dryer maintenance costs.
