ATLAS COPCO DESICANT AIR DRYER

CD 25+-145+

Reliable and compact

1. Overfilled and spring-loaded high-performance desiccant cartridges

Pressure dewpoint of -40°C/-40°F as standard (-70°C/-100°F as option).
Filter mat increases silencer lifetime by preventing dust exiting during regeneration.
Overfilled cartridges protect against desiccant ageing and overflow peak.
Horizontal operation possible.

2. Up-sized silencers with integrated safety valves

Advanced mufflers avoid back-pressure, increase purge efficiency, offer protection in case of clogging via the integrated safety valve, and reduce noise level during blow-off.

3. High-quality valve block with few moving parts

Designed to minimize pressure drop and increase reliability.

4. Corrosion protected design

Base, heads, panels, valves and extrusion profiles are corrosion protected, increasing dryer lifetime.

5. Filters

Pre-filter(s) protect desiccant against oil contamination, increasing desiccant lifetime.
After-filter protects network against desiccant dust, avoiding network contamination.
Can be mounted directly on the inlet and outlet of the dryer, for low pressure drop.
Easy to assemble and maintain as no extra piping or filter connections are required.

6. Advanced control and monitoring system

Timer control variant cycles defined to reach PDP target even at 100% load.
Auto restart after power failure function with cycle status memory.
Full status annunciation on LEDs, display and pressure gauges.
Remote alarm and remote control.
Purge Saver contact: the dryer can freeze purge cycle in case of unload/stop signal.
All controls are protected from water and dust thanks to the IP54 cubicle.

7. Dewpoint Dependent Switching (optional)

Real PDP monitoring (hygrometer).
PDP display on controller (and alarm).
The dryer will only switch to the next tower when the desiccant is saturated (based on PDP input). During that period, the dryer consumes no purge.

CD 110+-1400+:

Outstanding reliability and availability

1. High-quality desiccant

Pressure dewpoint of -40°C/-40°F as standard (-70°C/-100°F as option).
Up to 30% extra desiccant overfill to deliver consistent performance even in harsh conditions such as high temperatures and temporary overloads.

2. Stainless steel valves

Fully stainless steel high-performance butterfly valves with actuators ensure long lifetime.

3. Up-sized silencers with integrated safety valves

Advanced mufflers avoid back-pressure, increase purge efficiency, offer protection in case of clogging via the integrated safety valve, and reduce noise level during blow-off.

4. Galvanized piping with flanged connections

Flanged piping simplifies maintenance and minimizes the chance of leakage.
Pipe sizing is optimized to ensure a low pressure drop, resulting in energy savings.

5. Filters

Pre-filter(s) protect desiccant against oil contamination, increasing desiccant lifetime.
After-filter protects network against desiccant dust, avoiding network contamination.
Can be mounted directly on the inlet and outlet of the dryer, for low pressure drop.
Easy to assemble and maintain as no extra piping or filter connections are required.

6. Advanced control and monitoring system

Fitted inside a real IP54 cubicle for easy cabling and safety.
Monitors all parameters to ensure maximum reliability of the installation.

7. Dewpoint Dependent Switching

Real PDP monitoring (hygrometer).
PDP display on controller (and alarm).
The dryer will only switch to the next tower when the desiccant is saturated (based on PDP input). During that period, the dryer consumes no purge.

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 vessels are integrated into the top and bottom shells, lowering the total unit height.

BD 100+-3000+:

Rock-solid reliability & cost-efficiency

1. Long-life silica gel desiccant

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

2. Stainless steel valves

Fully stainless steel high-performance butterfly valves with actuators ensure long lifetime.

3. Low-wattage density heater

Stainless steel design ensures long lifetime.
Nickel-plated heater pipe protects against corrosion.
Heater is installed in an insulated heater pipe for most energy-efficient setup.
Optionally insulated vessels are available to further reduce heat losses and increase overall efficiency (standard on the -70°C/-100°F variant).

4. Galvanized piping with flanged connections

Flanged piping simplifies maintenance and minimizes the chance of leakage.
Pipe sizing is optimized to ensure a low pressure drop, resulting in energy savings.
