Read： 412 Time：20months ago Source：Transform the World with Simplicity

Air dryer is a kind of equipment that removes the moisture in the air to meet the needs of industrial production. According to the way of removing water, the air dryer can be divided into adsorption type, condensation type, low temperature type and hot air type.

adsorption air dryers use adsorbents to adsorb moisture from the air. The adsorbent commonly used in this dryer is silica gel, molecular sieve and activated carbon. The adsorption air dryer is suitable for the pharmaceutical, chemical and electronic industries, which have high requirements for dry air quality.

condensing air dryers condense the moisture in the air into liquid water through a refrigeration system. This dryer is suitable for the manufacture of chemical raw materials, food and beverage and metallurgy and other industries on the dry air humidity requirements are not too high occasions.

low-temperature air dryers use low-temperature refrigerants to cool the moisture in the air and condense it into water droplets. This dryer is suitable for use in areas where the flow of dry air is relatively large, such as the manufacture of automotive parts.

hot air dryer uses the hot air heated by the dryer to evaporate the moisture in the air and discharge it through the exhaust system. This dryer is suitable for industries that require higher drying speeds, such as the manufacture of plastic products.

air dryers are widely used in pharmaceutical, food, chemical, electronic and metallurgical industries. For example, in the pharmaceutical industry, the quality of dry air is very important to maintain the quality of drugs, extend the shelf life of drugs, and ensure hygiene in the pharmaceutical process. In the food industry, it is necessary to ensure the cleanliness and humidity of the dry air.

air dryers play a very important role in industrial production. Choosing a dryer suitable for your industry can not only improve product quality, but also improve production efficiency.
