DESICCANT AIR DRYERS FOR SUPERIOR PRODUCTIVITY

BD185+

COMPLETE PROTECTION FOR YOUR APPLICATION
Dry and clean compressed air is essential for a broad range of industrial applications. Yet it must be produced reliably, energy-efficiently and cost-effectively.Atlas Copco’s desiccant dryers protect your systems and processes. Their robust design ensures they operate with total reliability and deliver a constant, stable dewpoint in full load conditions and even during a temporary overload.

HOW DOES A DESICCANT DRYER WORK?

Wet air passes directly through the desiccant medium which adsorbs the moisture. 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 desiccant 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.
• Heat of compression dryers use the heat of the compression.

BD 185+ Dual Tower
Excellent performance, efficient performance

1 Quality desiccant

• High adsorption silica gel desiccant needs less reactivation energy than other drying agents.
• Dual-layer desiccant bed with a water-resistant bottom layer protects the high-performance top layer.
• Pressure dew point of -40°C/-40°F as standard (-70°C/-100°F optional).
• Up to 30% extra desiccant to deliver consistent performance even in harsh conditions such as high temperatures and temporary overloads.

2 Stainless steel valves
High-performance stainless steel butterfly valves with actuators ensure a long lifetime.

3 Low wattage density heater
• Stainless steel design extends lifetime.
• Heater is installed in an insulated pipe for an energy-efficient set-up.
• Insulated vessels are available as an option to further reduce heat losses and increase overall efficiency(standard on the -70 °C/-100 °F model).

4 Galvanized piping with flanged connections
• Flanged piping simplifies maintenance and minimizes the risk of leaks.
• Pipe sizing is optimized to ensure a low pressure drop for maximum energy savings.

5 Filters
• A pre-filter prevents oil contamination to increase desiccant lifetime.
• An after-filter protects the airnet from desiccant dust and network contamination.
• Can be mounted directly on the inlet and outlet of the dryer for low pressure drop.
• Easy to assemble and maintain. No extra piping and filter connections are required.

6 Advanced controland monitoring system
• Fitted inside an IP54 cubicle for easy cabling and safety.
• Monitors all parameters to ensure maximum reliability.

7 Dew Point Dependent Switching
• Real pressure dew point monitoring (hygrometer).

• Pressure dew point (and alarm).
• The dryer will only switch to the next tower when the desiccant is saturated, as measured by the dew point sensor. During this cycle time extension, the dryer consumes no purge air, resulting in a significant reduction in energy use.

8 Robust and compact design
• Standard frame, including forklift slots and lifting eyes for easy handling.
• Wide vessels ensure a low air speed and a longer contact time.
• Flanges connecting the vessels are integrated into the top and bottom shells, lowering the total unit height.
