Heatless desiccant Dryer CD55 with inlet and outlef filter, DC1 controller, beads desiccant, -40° PdP

Atlas Copco heatless desiccant dryers CD 25-260 - Competitive investment & superb reliability

1. Reliable operations

Designed to perform reliably at continuous operation of 100% air flow, whereas most dryers on the market are only built to work at 70% to 80%. This includes a constant pressure dew point of -20°C/-5°F or -40°C/-40°F as standard. The pressure dew point can also be adjusted for seasonal or application changes.

2. Unique manifold-valve design

• Large pipe diameter minimizes pressure drop for advanced energy savings.

• Electronically operated 3/2 valve reduces risk of breakdowns and offers reliable control during air flow fluctuations. Vessel switching operates unfailingly even in rough conditions.

• Service openings ensure easy service of the moving parts of the valve system.

• Clever strainer design minimizes pressure drop, regeneration times and energy consumption. Its “swirl” technology ensures optimal distribution of the air flow and decreases wear of the desiccant.

3. Advanced control and monitoring system

• 4-line display in 23 languages.

• Service alarms and general alarm relay.

• Monitors all parameters to ensure maximum reliability.

• Allows for synchronization with the compressor, turning on/off when the compressor does.

• Service indications (4,000, 8,000 and 40,000 hours) and warnings.

4. Service and maintenance-friendly

• Desiccant bags allow for quick replacement without spilling adsorbent material.

• A spring covers the bags to prevent damage by desiccant moving due to pressure pulsations.

5. Attached filters

• A durable PD+ pre-filter prevents oil contamination to increase desiccant lifetime and is included for installation in the air piping.

• A DDp+ after-filter protects the air-net from desiccant dust and network contamination and is included for installation in the air piping.

6. Nozzle purge set

Offers flexibility in optimizing regeneration pressure for lowest purge air consumption. Standard is 7 bar; 4- and 10-bar nozzles come as separate parts.

7. Advanced options

• Pressure dew point sensor required for Dew Point Dependent Switching.

• Wall mounting kit
