Product Summary
The ADH series is a micro-heat regenerative desiccant dryer that integrates the advantages of heated and heatless regeneration. It heats purge air to regenerate desiccant, achieving better regeneration performance with only 6% regeneration air loss. Suitable for applications requiring stable dew points down to -52°C, such as PSA nitrogen-oxygen generators, laser cutting, pharmaceutical fermentation, and battery workshops. The dryer features microcomputer control, LCD/LED display, fault diagnosis, and automatic safety protections. It can be customized with stainless steel material, ATEX, ASME, or CE certifications.
Key Selling Points
- Low regeneration gas consumption (≤6%): Heated regeneration method reduces purge air requirement, lowering energy costs.
- Stable dew point (≤ -40℃ / ≤ -52℃): Ensures consistent compressed air quality for critical processes.
- Microcomputer control with LCD/LED display: Real-time monitoring of equipment status for easy operation.
- Automatic fault diagnosis and alarm: Multi-function protection minimizes downtime.
- Non-contact solid-state switch heating control: Long service life and precise temperature control.
- Automatic switch to heatless mode on micro-heat failure (patented): Ensures continuous operation even in fault conditions.
- Optional online dew point control (patented): Maximizes energy savings by adjusting regeneration based on actual dew point.

Materials and Structure
Standard construction uses carbon steel; stainless steel SS304 is available for corrosive environments. The twin-tower design with heated regeneration ensures low purge gas consumption and stable performance.
Applications
- Pre-treatment for large-scale PSA nitrogen-oxygen generators
- Gas purification and cylinder filling stations
- Central gas supply for multiple laser cutting and automatic welding stations
- Pharmaceutical aerobic fermentation, medical oxygen making, aseptic packaging lines
- Lithium battery workshops, photovoltaic wafer processing, semiconductor assembly
- Fine chemical reactions, powder material pneumatic conveying
- Large-capacity beverage blow molding and bottling plants
Customization
We offer customization in materials (SS304), certifications (ATEX, ASME, CE), and pressure ratings (up to 3.0 MPa). Optional remote monitoring and control features are also available.
Case Study
Petroleum Pipeline Project (Uganda): An EPC general contractor installed three units of our compressed air dryers for pipeline-type compressed air drying. Over three years of operation, the dryers have maintained stable performance, leading to repeat purchases and refurbishment orders. The portability and low dew point capability were highlighted as key advantages.
Frequently Asked Questions
1. What is the difference between micro-heat and heatless desiccant dryers?
Micro-heat dryers use a small amount of external heat to regenerate the desiccant, reducing purge air consumption to about 6%. Heatless dryers regenerate by expanding a portion of dry air, which consumes more purge air (typically 15-20%).
2. What dew point can I expect?
The ADH series can achieve a pressure dew point of ≤ -40℃ or ≤ -52℃, depending on your requirement.
3. Can the dryer handle high-pressure applications?
Yes, standard working pressure is 0.6-0.8 MPa, but options up to 3.0 MPa are available.
4. What materials are available?
Standard is carbon steel, with stainless steel SS304 optional for corrosive environments.
5. Do you provide international certifications?
We can provide customization to meet ASME, CE, or ATEX standards as required.
6. What is the typical energy saving?
By using heated regeneration, the purge air loss is reduced to ≤6%, resulting in significant energy savings compared to heatless dryers.
7. Can the dryer be connected to a central control system?
Yes, optional RS485/RS232 communication interfaces and joint control functions are available.
8. What safety features does it have?
The dryer has multiple fault diagnosis, alarm, and automatic processing functions, including a re-energised heating safety protection device (patented).
