The working principle of desiccant air dryer

The adsorption drying principle is based on the ability of the desiccant material to adsorb water vapor from the compressed air. Filters before the dryer protect it, while filters after the dryer eliminate desiccant dust The drying process consists of three phases:

Drying phase

Wet air from the compressor passes through the inlet filters ( 1 )which remove the oil.The air then enters into tower A. The desiccant in tower A adsorbs the water vapor molecules. After a fixed(E) or variable(x) time the inlet valve(2) devilates the air flow from tower A to tower B, which then becomes the operational tower.

Regeneration phase

During the drying phase in tower A, some dry is deviated into the top 0f tower B.where it extracts the trapped vapor from the desiccant matenal. During this phase,tower B is open to the atmosphere, allowing the purge air to expand.The silencers(3) on the outlet ensure quiet operation.

Pressurization phase

Once regeneratgion has taken place and tower B is pressurized, the inlet valve(2) changes the air flow again.

Notes:

On DB05-6 the outlet filter is built inside the desiccant cartridge

Recommended but not included on DB 05-64.

Key benefits of desiccant air dryer:

Longer life span of your equipment and distribution network due to less wear

Greater productivity and lower maintenance costs thanks to less breakdowns

Multiport inlet and outlet which ensures fast and easy installation

Higher final product quality

Increased reliability and reduced risk for leaks

Energy savings with lower pressure drops

Pressure dew point sensor

 

Description:

Micro heat regenerative adsorption pressure desiccant dryer with no heat regeneration principle is basically the same, the difference is that it used to regenerate the low-pressure dry air before re-entering the regeneration tower after receipt of the desiccant dehumidification in the structure increased heating device, on the increase in the regeneration process receipt and cold blowing processes. slightly hot regenerated adsorption dryer advantage of less energy waste, only 6%. Switching cycle is long and less engine wear, improved equipment reliability. It is the final product gas dryness ratio heatless with even better.
