Features of the Heatless Purge Desiccant Air Dryer
●The Heatless air dryer boasts a scientific and reasonable structural design, novel appearance, elegant appearance, long-term high efficiency, stable performance, convenient operation, maintenance and maintenance, and easy installation.
●Professional anti-rust treatment is applied to the inner wall of the barrel, and it will not rust for 10 years under normal working conditions.
●Flexible and stable pneumatic valve, reliable operation and long service life.
●The filling capacity of the adsorbent is extremely abundant, and the large-capacity desiccant bed ensures sufficient contact time between the air and the desiccant, so that the desiccant can fully absorb water and achieve a stable outlet dew point. Ensure the stability of the dew point of the outlet air and the effect of water removal.
●Excellent quality muffler can effectively reduce product noise, and has pressure protection function to improve product safety.
●Keep an appropriate flow rate of air in the adsorption cylinder, which can not only ensure full contact between the compressed air and the adsorbent, but also prevent the adsorbent from moving and pulverizing.

Note:
Model number remarks: “F” as fixed speed, “V” as VSD. Due to the potentially different rotation speeds of motors, the air flow rates of fixed speed represent the minimum in the range (i.e 30kW 8 bar 5.67m³/min), while VSD can reach the maximum at full loading.
Standard voltage in 380V (+/-10%), 50Hz +/-2% and available for customized voltage 220/380/440/460V/60Hz.
In cases of elevated altitudes, extreme temperatures, excessive humidity, heavy dust exposure, or any other challenging operational environments, we can offer tailored product designs to meet your specific needs. Customization is available to align with your unique requirements.

Frequently Asked Questions
What is a Heatless Purge Desiccant Air Dryer？
A heatless purge desiccant air dryer is a type of dryer that uses the principle of pressure swing adsorption and regeneration to remove moisture from compressed air. It operates using self-generated heat, without the need for an external heat source. Compressed air flows alternately through two adsorption towers, with one tower in a high-pressure state where the desiccant absorbs moisture, while the other tower is regenerated by low-pressure gas flowing through a separate regeneration line. This process allows for efficient and effective drying of compressed air.
For example, single-stage compression screw machine rotor: the pressure at the inlet end is about 1 bar of atmospheric pressure, compressed by the rotor to an outlet pressure of 8 bar, the compression ratio of the compression process is 8/1, that is, the single-stage compressor compression ratio of 8. While the pressure at the inlet end of the dual-stage is about 1 bar of atmospheric pressure, compressed by the first-stage rotor to an outlet pressure of about 3 bar, and then into the second-stage rotor compression to enhance the pressure to the required 8 bar The compression ratio of the first stage low pressure rotor is about 3, and the compression ratio of the second stage high pressure rotor is 8/3 ≈ 2.67, i.e. the compression ratio of the second stage is about 2.67. The maximum compression ratio of the two-stage compression rotor system is about 3.
The Heatless Purge Desiccant Air Dryer operates on the principle of pressure swing adsorption and regeneration cycle
using self-generated heat (without the need for an external heat source) for adsorption drying. Compressed air flows alternately through two adsorption towers, with one tower in a high-pressure (working pressure) state where the desiccant absorbs a large amount of moisture, while the other tower is regenerated by low-pressure gas from the regeneration gas pipeline, releasing the moisture absorbed by the desiccant.
