Absorptive Dryers Series

Powerhouse in a box

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

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.

The HAD series waste heat regeneration adsorption compressed air dryer is a purification device designed to extract moisture from gases using the molecular forces on the surface of porous solid substances, resulting in lower dew point temperatures and the purification of dry, clean air. The system utilizes activated alumina as the adsorbent, with pore sizes similar to the diameter of water molecules, and operates based on the internationally advanced principle of variable-temperature and variable-pressure adsorption. In the initial stage, the compressed air from the final stage of the compressor (approximately 110°C) enters a tower, regenerating the adsorbent by exploiting its characteristic of lower adsorption rate at higher temperatures under the same pressure. The air then undergoes cooling to around 40°C through a cooler, proceeds through a gas-liquid separator for water removal, enters the working tower for adsorption drying, and finally passes through a filter for purification, resulting in the production of finished air. After a certain period, the air enters the drying tower directly, undergoes adsorption drying through a cooler and a gas-liquid separator, retains a portion of the dried air (1-2%) at the air outlet, and 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.
