ADH-039 Micro-Heat Regenerative Adsorption Dryer operates on the principle of using specialized molecular sieves for gas purification to remove saturated water vapor from compressed air by leveraging the difference in volume between water molecules and air molecules. The water molecules are easily adsorbed into the molecular sieve particles, and 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 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. Adsorption dryers are generally categorized into two types: heatless regenerative adsorption dryers and micro-heat regenerative 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 a dew point of -40°C, meeting the requirements for most equipment air usage.

About FD Micro-Heat Adsorption Dryer:

1. Hangzhou Xinlong is the first in the industry to truly achieve a full range of micro-heat dryers equipped with a regeneration flow measurement and control device. Precise regeneration flow ensures thorough regeneration.

2. Hangzhou Xinlong's micro-heat dryers utilize a self-developed ultra-efficient electric heater. The precise design ensures that the regeneration gas requiring heating fully and thoroughly contacts the heater for heat exchange, with no blind spots, making the efficiency far superior to competitors using U-type 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, preventing damage from dry firing.

3. Hangzhou Xinlong has always focused on the nitrogen and oxygen generation air separation industry, as well as energy-saving modifications 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 (special 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. Designed entirely according to the high-frequency valve and control requirements of the air separation industry, they offer an exceptionally long lifespan.

4. Xinlong dryers' adsorption tanks and pipelines are automatically welded and treated with shot blasting and sandblasting processes, ensuring strong paint adhesion.

5. Xinlong Fd brand dryers feature high industry-standard configurations, stable quality, aesthetically pleasing craftsmanship, and exceptional cost-effectiveness. They are filled with an ample amount of high-quality, high-performance adsorbent, ensuring stability and reliability.
