Blower Purge Desiccant-HANFILTER

Powerhouse in a box

This model based its technologies from US HANKISON and Gemany ZANDER absorptive dryer, and combines with the practical operation features in China to create more stable and more reliable dryers with scientific design and manufacturing, thus raising the customer satisfactions. "HANFILTER" absorptive dryer won several national patent with its state-of-art technology, stable running, low dew point and high stability. Moreover, HANFILTER is also one of the companies in preparation of the industry standards "General Purpose Refrigerated Compressed Air Dryers" and "General Purpose Desiccant Compressed Air Dryers", and thus becoming the one of the few domestic manufacturers with top technology.

Stable outlet pressure and dew point

1. Unique sorbent bolus with diameter of 3.0mm, gaining bigger activated surface area, higher absorptive power and anti- crushing strength, longer life.

2. 30% extra sorbent to compensate the natural aging of the sorbent, allowing a stable pressure dew point.

3. Excellent absorptive cartridge based on the high diameter ratio from the US HANKISON products, taking into account the transportation and guaranteeing the contact time is no less than 5.2 seconds.

State-of-art shunting unit design

In considering that the domestic dispenser encounters the cross flow phenomenon, the company designs to utilize a better shunting device based on the Germany ZANDER absorptive dryer to perform an evenly contact of compressed air and the sorbent, completely eliminating the cross flow phenomenon.

Reliable valve motion and state-of-art imported electrical parts

Use good performance and reliable butterfly valve and solenoid valve, with lifecycle exceeding 1 million times.

Blower Purge Desiccant Compressde Air Dryers (Zero Air Loss)

HAD Series External Heating Zero Purge Air Regeneration Adsorption Compressed Air Dryer is an advanced purification device utilizing molecular forces on the surface of porous solid substances to extract moisture from gases, achieving lower dew point temperatures and providing clean, dry air. The adsorbents used are activated alumina and molecular sieves with pore sizes similar to water molecules, applying the internationally advanced principles of variable-temperature and variable-pressure adsorption. During adsorption at room temperature, the vapor pressure of water molecules in the air exceeds that in the adsorbent, causing water molecules to enter the adsorbent and condense into water droplets on its surface, releasing condensation heat stored in the upper part of the adsorption tower. During regeneration, a Roots blower heats atmospheric air to approximately 200°C through a heater and passes it through the regeneration cylinder. This significantly reduces the adsorption capacity of the adsorbent, allowing water molecules to escape. Simultaneously, the heat stored in the adsorption tower contributes to saving the power of the heater. After a certain duration, the air enters the drying tower directly through a cooler from the lower part for adsorption drying. It then enters the tower where the adsorbent was regenerated by hot air just before, further enhancing regeneration. After a specific duration, the regeneration gas is closed, and the regeneration tower is pressurized for standby. This cycle repeats continuously. The dual-tower system operates alternately, continuously delivering dry and clean compressed air. The purified air achieves a low-pressure dew point, ensuring deep drying to provide water-free, oil-free, high-purity compressed air to meet diverse gas requirements.
