Atlas Copco BD 970 desiccant air dryer consist of two towers filled with desiccant such as activated alumina, molecular sieves or silica gel. Wet compressed air passes directly through the substance, which adsorbs the moisture. The desiccant has a finite adsorption capacity before it must be dried out. Hence the twin tower design. While one tower is drying air, the other is being regenerated.
Twin tower BD 970 desiccant air dryer working principle
Adsorption dryers are used when the compressed air application requires a pressure dew point below 0°. The regenerative desiccant dryers consist of two pressure vessels. Both vessels are filled with desiccant. One vessel is removing moisture from the compressed air.
Wet air passes directly through the desiccant bed which adsorbs the moisture. When this vessel is saturated with moisture the valves will switch and lead the air to the other standby vessel. During adsorption in the other vessel, the first vessel will be regenerated. It’s a cyclic process.
The desiccant medium has a finite capacity for adsorbing moisture before it must be dried out, or regenerated. To do this, the tower containing saturated desiccant medium is depressurized and the accumulated water is driven off.
How this happens depends on the type of dryer.
- Heatless dryers use only compressed air as a purge
- Blower purge dryers use a combination of air from an external blower, heat, and minimal compressed air
- Blower zero purge dryers use a combination of air from an external blower, heat, and zero compressed air
- Heat of compression dryers use the heat of the compression
- Heated purge dryers use heat and small amount of compressed air
BD 970 Desiccant Air Dryer Benefits
Maximize energy savings
Our desiccant air dryers BD+, CD+ and XD+ adapt their energy usage to the real load. That is how they make you save substantially.
Protect your production
Our patented Elektronikon control ensures maximum operating efficiency. It protects your production with advanced warnings for service and operating parameters.
Easy installation
Supplied ready for use, no hidden installation costs. All components including silencers, sensors and the control unit are mounted on a solid base frame with integrated forklift slots.
Longer service intervals
Compared to standard activated alumina, the use of high-grade desiccant bead materials can double your set-up’s lifetime. Stainless steel significantly extends your valve service intervals, reducing your production down-time and maintenance costs
Optimal durability
Improve your desiccant air dryer lifetime. Its proven, rugged design allows for switching the high-quality stainless steel valves.

Why choose the BD 970?
Unlike standard heatless dryers that waste 15-20% of your compressed air for regeneration, the BD 970 utilizes external blower purge technology . This innovative design significantly reduces your total cost of ownership (TCO).
Key Benefits for Your Business:
- Extreme Energy Savings: By using an external blower and minimal compressed air, this dryer slashes energy consumption compared to traditional heatless dryers .
- Reliable Performance: Achieves a consistent pressure dew point of -40°C (-40°F), ensuring your processes are safe from condensation, even in winter .
- Environmentally Friendly: Reduces CO2 emissions and lowers your carbon footprint.
- Low Maintenance: Designed for continuous operation in harsh environments, reducing downtime.
Stop overpaying your electricity bill.
Every cubic meter of air you save on purge is cubic meters you pay for. The BD 970 pays for itself quickly through energy efficiency.

Mike R –
Huge energy savings and rock-solid performance
We replaced an old heatless dryer with the Atlas Copco BD 970, and the difference in our electricity bill was immediate. The blower purge technology really works – it uses far less compressed air for regeneration. The -40°C dew point is stable, and we’ve had zero moisture issues in our lines since installation. The unit arrived brand new in a wooden crate, exactly as described. Worth every penny.
Linda –
Genuine Atlas Copco quality – smooth transaction
We bought this BD 970 for our expanded production line. The dryer came fully assembled on a solid base frame with fork slots, making installation easy for our team. The build quality is excellent – stainless steel valves and high-grade desiccant. It handles our 2056 cfm flow without a problem. The supplier provided clear shipping options (we chose DAP), and delivery was within the quoted lead time. Highly recommended.
