Heatless Regeneration Adsorption Dryer–HH Series

The HH Series Heatless Regeneration Adsorption Dryer is designed to deliver stable and ultra-dry compressed air through pressure swing adsorption (PSA). Equipped with high-efficiency activated alumina and molecular sieve adsorbents, this series ensures a consistent outlet dew point of ≤ –40°C, meeting the moisture-control requirements of demanding industrial processes.

The HH Series operates without external heating, resulting in lower energy usage, simple structure, and fewer maintenance needs. Its durable design ensures reliable moisture removal, making it ideal for environments where high-quality, moisture-free compressed air is essential.

Product Features

• Highly Stable Moisture Removal
  Achieves a low dew point (≤ –40°C), ensuring dry and clean compressed air.

• No-Heat Regeneration System
  Uses PSA technology to regenerate adsorbents without heating, reducing operating costs.

• High-Performance Adsorbents
  Activated alumina + molecular sieve provide strong adsorption capacity and long service life.

• Reliable for 24/7 Industrial Use
  Ensures continuous operation with minimal maintenance requirements.

• Efficient Airflow Design
  Reduces pressure drop and enhances overall drying efficiency.

• Compact & Easy Installation
  Suitable for new system integration or upgrading existing compressed air systems.
