FAQ
Q1. How does a heatless adsorption dryer work?
A. Principle: It uses a dual-tower pressure swing adsorption (PSA) system: While one tower adsorbs moisture, the other tower purges and regenerates the adsorbent (molecular sieve/alumina) with a small amount of dry air (approximately 12-15%).
Cycling: The dual-tower operating state is automatically switched (adsorption tower → regeneration tower) every 4-10 minutes, ensuring continuous air supply.
Q2. Is 15% regeneration air consumption a waste? How can it be reduced?
A. Necessity: Regeneration air consumption is an inherent characteristic of physical adsorption and is used to remove moisture from the adsorption tower.
Optimization Method: Optimize the model to match actual air consumption.
Install a dew point energy-saving control system: Automatically adjust regeneration air consumption based on humidity (reducing it to 8-10%).
Q3. What causes a sudden increase in outlet dew point (e.g., -20°C to 0°C)?
A. Adsorbent failure, adsorbent pulverization, valve leakage, or incomplete regeneration.
Q4. Does a heatless adsorption dryer require a power source?
A. Only control power is required: to drive the solenoid valve and controller (power <100W), no high-power electricity is required (unlike micro-heating types).
Q5. Which industries require heatless adsorption dryers?
A. Semiconductor manufacturing, medical ventilators, lithium battery coating, and food packaging.
Q6. What precautions should be taken when restarting after a shutdown?
A. Adsorbent regeneration: If the system has been down for >48 hours, the regeneration process must be manually initiated to prevent wet adsorbent from clumping.
Gradual loading: Start with a low flow rate for 10 minutes, then gradually increase the load.
