Atlas Copco CD+ 18 heatless adsorption dryer

The CD+ dryers are heatless adsorption dryers, designed to remove moisture from compressed air for industrial applications. Their working principle is based on the PSA (Pressure Swing Adsorption) process.

The CD+ dryers are available in versions to reach pressure dew points down to:

• -20°C / -5°F / ISO* Class [-:3:-]

• -40°C / -40°F / ISO* Class [-:2:-]

• -70°C / -100°F / ISO* Class [-:1:-]

*Classification acc. ISO8573-1:2010

They are by default equipped with a DC1 electronic controller. An Elektronikon controller with graphical display, including a PDP sensor (pressure dew point sensor) to lower the energy

consumption, is available as option. The dryers are designed for automatic & continuous

operation, for indoor use and altitude operation up to 2000 m (6560 ft.). Inlet air pressures are

allowed up to 14bar.

The CD+ dryers with optional PDP sensor offer a tailor made pressure dew point for the application.

In both the DC1 as the Elektronikon, the PDP can easily be set upwards from the standard dew

point setting of -40°C (-40°F) or -20°C (-5°F), to a set point that perfectly matches your application.

Their fully enclosed canopy design, and the use of durable aluminum extrusions which serve as

pressure vessels, makes them very robust units that can withstand though ambient conditions.

The enclosed canopy design also helps to limit the noise level during operation, especially during

blow-off phase.

A uniquely designed valve manifold in combination with a special silencer system ensures not only

high reliability, also the very low pressure drop of this combination contributes to having an

absolute minimum regeneration air consumption.
