Micro Heat Regeneration Adsorption Dryer

Key Features

• Hybrid Regeneration Method

  • Combines pressure swing adsorption (PSA) and temperature swing adsorption (TSA) principles for superior drying performance.
  • Adsorption (working) occurs at room temperature and higher water-vapor partial pressure.
  • Desorption (regeneration) occurs with slightly heated, low-humidity regeneration gas, improving moisture removal efficiency.

• Energy Efficiency

  • Uses slightly heated purge gas to significantly reduce regeneration gas consumption compared with conventional non-heated (heatless) dryers.
  • Optimized thermal design minimizes fuel/electric heating demand while keeping regeneration effective.

• Stable Switching and Reliability

  • Avoids the short switching-time drawback of pure non-heat regeneration dryers by balancing thermal and pressure mechanisms.
  • Designed for continuous industrial operation with reliable cycle control.

• Wide Industry Applicability

  • Suitable for metallurgy, power generation, electronics, food, chemical, petroleum, pharmaceutical, tobacco, instrumentation, and automation sectors.

• Efficient Moisture Removal Mechanisms

  • Moisture is removed from the adsorbent by thermal diffusion assisted by the high pressure differential of the regeneration gas (heated dry air).

Technical Advantages

• Lower Purge Gas Consumption compared to heatless dryers.
• Improved Dew Point Stability under varying loads.
• Reduced Operating Cost through optimized regeneration heat and gas usage.
• Compact Footprint for micro / small to medium capacity installations.
• Fast, Predictable Cycle Control with minimized moisture breakthrough risk.

Typical Applications

• Compressed air systems for process lines and instrumentation.
• Electronics manufacturing where low moisture is critical.
• Pharmaceutical and food processing for product quality and safety.
• Power plants and metallurgy for pneumatic systems and instrument air.
• Chemical and petroleum facilities requiring stable dew points.
