ADL Series Heatless Compressed Air Desiccant Dryer

Pressure Swing Adsorption Type | 0.5–500 Nm³/min | Low Regeneration Loss

Product Summary

The ADL Series heatless compressed air desiccant dryer uses the pressure swing adsorption principle to remove moisture from compressed air. It regenerates via dry air purge without external heat, achieving a pressure dew point as low as −40°C. Designed for continuous industrial operation, it offers a rated flow rate from 0.5 to 500 Nm³/min at working pressure 0.6–0.8 MPa (optional up to 3.0 MPa). The dryer features low regeneration air loss (≤12%) and pressure loss (≤0.02 MPa), ensuring efficient and stable performance. Its microcomputer control with LCD/LED display and multiple alarms guarantees easy monitoring and fault detection. Optional online dew point control and RS485/RS232 remote communication are available.

Key Selling Points

Applications

Pre-treatment for PSA nitrogen generators, PSA oxygen generators, and high-purity gas purification plants
Fiber-laser cutting, laser welding, precision metal machining
Pharmaceutical manufacturing, hospital oxygen supply, laboratory gas supply
PCB processing, lithium-battery production, electronic component assembly
Beverage bottling, plastic-bottle blow-molding, food processing
Fine-chemical industry, precision injection molding, new-material processing

Customization

We offer customization of material (stainless steel), certification (ATEX, ASME, CE), dew point levels, control interfaces (RS485/RS232), and cycle times. The optional online dew point control with national patent technology maximizes energy savings.

Case Study

Pakistan Distributors (2021): 10 units of ADL dryers used as pre-treatment for oxygen-enriched combustion in blast furnace. After 5 years of operation, oxygen purity and flow rate remained stable.

FAQ

What is the principle of heatless desiccant drying?

It uses pressure swing adsorption: moist compressed air passes through a desiccant bed that adsorbs water vapor. A portion of dried air is expanded and used to purge the off-line bed, regenerating it for continuous operation.

What dew point can I expect?

The standard dew point is ≤−40°C, and ≤−52°C is available as an option. The actual dew point depends on inlet conditions and flow rate.

What is the recommended maintenance schedule?

Periodic inspection of desiccant condition and replacement as needed, typically every 2-3 years depending on operation conditions. Check filters and valves regularly.

Can the dryer handle high inlet temperatures?

The maximum inlet temperature is 38°C. For higher temperatures, a pre-cooler or refrigeration dryer may be required.

Is remote monitoring possible?

Yes, with optional RS485/RS232 interface, you can connect to a SCADA or remote control system for joint monitoring and control.

Can the dryer be customized for specific pressure or flow?

Yes, the working pressure can be up to 3.0 MPa and the flow rate ranges from 0.5 to 500 Nm³/min. We can design to meet your specific needs.

What certifications are available?

We can provide ASME, CE, and ATEX certified versions for required markets.
