Compressed air treatment

Air quality control is the key to a healthy, well-controlled industrial process. For almost 40 years, we have applied our expertise to support the sustainability of your industry by providing drying and filtration solutions tailored to the most demanding requirements.

Low pressure (<16 bar) adsorption dryers PSA technology

25 m³/h

2900 m³/h

Our DA dryer range uses the principle of pressure swing adsorption to efficiently dry compressed air before it enters the network. With its highly efficient twin-tower heatless system mounted on a functional frame, it achieves the required pressure dew point (-40°C to -70°C). Each tower contains a precisely measured volume of desiccant that adsorbs the moisture present in the air. During regeneration, the desiccant releases the trapped water molecules under the effect of the purge air, making it ready for a new drying cycle.

The humid air produced by the compressor flows directly into the dryer and passes through column A. (For maximum efficiency, we recommend adding an SCF filter when operating in fully saturated humid conditions, especially if no separator is installed downstream of the compressor), after first passing through two high-efficiency CF filters, grades M and S.

Inside the column, the compressed air passes through the desiccant bed where water vapor is adsorbed. The dried air then flows through a CF particle filter (P grade), which retains any desiccant particles (25 microns), before being delivered to the air receiver or end users in the compressed air network.

Meanwhile, a small portion of the dried air is diverted into column B and vented through high-performance silencers. This process removes the retained moisture and regenerates the desiccant, preparing it for the next cycle.

Caractéristiques techniques

Limited energy costs

Design completely optimised with its two columns integrated on a single chassis amongst others to promote scavenging the desiccant and ensure reduced air consumption. Thanks to their digital display, DA dryers offer the possibility of hygrometric control and setting dew point permitting control and use in line with your requirements.

Optimised design

Footprint reduced with a compact vertical design and the possibility of direct wall mounting in models DAM25, DAM50 and DAM75 with wall supports. Resilient and with long life thanks to anti-corrosion paint and a chassis with oven-baked epoxy paint.

Plug and play product

Adsorption dryer ready for use with all integrated components directly in the DA dryer to facilitate major simplicity of use over time. Totally stand-alone, it requires no manueal intervention for control during use.

Skid version

Possibility of a basic version for integration of the material in a process/skid compressed air with report of the control and settings on a central console. Ideal version for integrators.

Easy Maintenance

Optimal accessibility to the various components reducing maintenance time and limiting usage costs. Maintenance kits are available to you to carry out maintenance as required.

Finishes

- Tempo finish that allows a fixed switching of the adsorption dryer regeneration cycles.

- Thermo finish which optimises the drying cycles according to the flow rate, pressure and inlet temperature of the compressed air.

- Hygro finish which integrates the hygrometry management and optimises the drying cycles according to this data.

Energy savings

Load loss optimised across our range of DA dryers thanks to re-design that limits it to a maximum of 0.2 bar (average 0.15 bar), without taking into account filters upstream or downstream of the dryer. Coupled to high performance CTA filters in the CF series, load loss is limited to a maximum of 0.45 bar for class 2 particles in line with norm ISO 8573.1-2010.

Optimal security and control

Thanks to its microprocessor that controls the functioning of the DA adsorption dryer, it is possible to set a range of alarms linked to use of the dryer and thus generate maintenance and non-optimum-functioning alerts. All these alerts can be reported on a central control panel in your compressed air installation.

Performance guarantee

Manufactured and tested at our French factory and complying with the ISO 8573.1-2010, class 2 pollution, class 1 humidity, our dryers ensure you optimum use and guarantee over time. The digital controller ensures the best use and control of the cycles and ensures you a dew point under pressure at the expected values. All tanks are designed and tested in line with the CODAP code of construction observing European norms in force for appliances under pressure.

Limited sound pressure

Sound nuisance is reduced thanks to the isophonic design worked accordingly to facilitate reduction of noise and sound levels.

Simplified maintenance

Simple access from the central console that facilitates optimum maintenance of the dryer. Direct accessibility to all components.
