ADH-008 Micro-Heat Adsorption Dryer operates on the principle of utilizing the difference in volume between water molecules and air molecules. It employs a gas purification molecular sieve to filter out saturated water vapor from compressed air, easily adsorbing water molecules within the molecular sieve particles. The molecular sieve is then regenerated to restore its water-absorbing capacity. In simple terms, it achieves drying through the principle of pressure swing adsorption. When the inlet air temperature of the adsorption dryer is 2°C, using molecular sieve as the adsorbent, the dew point of the compressed air can reach even lower temperatures. Generally, adsorption dryers are categorized into two types: heatless regeneration adsorption dryers and micro-heat regeneration adsorption dryers. The dew point of heatless regeneration is higher than that of micro-heat regeneration, with heatless regeneration typically around -20°C, while micro-heat regeneration can achieve -40°C. This meets the requirements for the vast majority of equipment air usage.

FD Series Micro-Heat Regeneration Adsorption Dryer Model Specifications Parameter Table:

1. FD full range of micro-heat dryers are equipped with a regeneration flow calculation and control device. Precise regeneration flow ensures thorough regeneration.

2. FD micro-heat dryers utilize a highly efficient electric heater developed through R&D. The precise design ensures that the regeneration gas requiring heating fully contacts the heater for heat exchange without blind spots, making efficiency far superior to competitors using U-shaped heating tubes. The heating tubes are made of high-temperature resistant 321 stainless steel, which is the core technology behind Xinlong heaters' durability. The entire series of heaters are equipped with dry-fire protection. If gas fails to enter the dryer or the regeneration gas volume is low with low pressure, the protection system immediately detects and signals to protect the heater from dry-fire damage.

3. FD has always focused on the nitrogen and oxygen generation air separation industry, as well as energy-saving retrofitting for air compressors, with particular emphasis on stability and large flow with ultra-low pressure drop. Valves below DN50 are fully stainless steel pneumatic angle seat valves (high-frequency valves for nitrogen and oxygen generation), with a lifespan of at least 5 years. The solenoid valves feature Airtac valve bodies with imported coils from the Italian brand AMISCO. They fully meet the high-frequency valve and control requirements of the air separation industry, ensuring an exceptionally long lifespan.

4. The adsorption tanks and pipelines of FD dryers are automatically welded and treated with shot blasting and sandblasting processes, resulting in strong paint adhesion.

5. FD brand dryers feature high industry-standard configurations, stable quality, aesthetically pleasing craftsmanship, and exceptional cost-effectiveness. The adsorbent is filled abundantly, and the adsorbent itself is of high quality and performance, ensuring stability and reliability.
