Adsorption dryer is through the "pressure change "(pressure change adsorption principle) to achieve the drying effect. Due to the ability to hold water vapor and air pressure is inversely proportional to its part of the dry air (called again angry) decompression expansion to atmospheric pressure, the pressure change make expansion air more dry, then let it flow through turn on the air must be regenerated desiccant layer (i.e., have to absorb enough water vapor drying tower), the water in the dry gas sucked out desiccant, it out of the dryer to achieve the goal of dehumidifying. The two towers work in a cycle, without heat source, continuously providing dry compressed air to the user's gas system.

The absorber is classified according to the adsorbent regeneration mode, which can be mainly divided into two kinds: non-thermal regeneration micro-thermal regeneration absorber and thermal regeneration micro-thermal regeneration absorber. Because there is no heat micro-heat regenerative drying machine is based on isothermal adsorption work, also known as "pressure swing adsorption" heat micro-heat regenerative drying machine is based on isothermal adsorption work, also known as "temperature swing adsorption". In practical use there is a kind of called micro-heat dryer, from the form, micro-heat regenerative dryer is also the regeneration gas heating, but because it is used in the regeneration gas is from its own moisture content is very low dry air, so it is also a "pressure swing adsorption" dryer.
