PARSEC adsorption dryers have been developed to meet the expectations of users
concerned with obtaining compressed air that meets the most demanding quality criteria.
By delivering a pressure dew point of -40 ° C, they effectively protect the majority of
industrial processes including installations whose external networks are exposed to frost.
For the most demanding applications, the dew point can be brought to -73 ° C under
pressure. The latter is then able to meet the strictest specifications, such as those intended
for food or pharmaceutical applications.
Robust in design, they are designed for fully automatic and uninterrupted operation. Flexible
to use, they nevertheless lend themselves easily to intermittent use.
Their low investment cost meets the current economic expectations of the industry

All pneumatic circuits suffer from the drawbacks linked to the presence of water vapor in the
However, installing a refrigeration dryer does not solve this problem in all cases. It is here,
for dew points below + 3 ° C, that the PARSEC series dryers find their field of application.
Reliable and flexible to use, they allow extremely low dew points to be reached (down to -70
° C under pressure).
These values are able to satisfy the most demanding demands, whether physical (frost
protection), or functional (water vapor content imposed by the manufacturing process)
PARSEC dryers provide air quality that meets the needs of all industries for impeccable
compressed air quality.
PARSEC dryers operate on the principle of dynamic adsorption with regeneration by
This technology, invented by Dr. Charles SKARSTROM in the 1950s, allows an air flow to be
dried without interruption on a 2-column system by alternating fixed or optimized
regeneration of the desiccant.
The moisture carried by the compressed air is captured on the surface of a porous and solid
hygroscopic material (desiccant). While one column is in the drying phase, the other is
simultaneously regenerated by a flow of dry air taken from the dryer outlet, expanded to
atmospheric pressure and exhausted via an exhaust silencer.
After the regeneration phase, the column is repressurized, and the cycle then reverses
automatically in order to regenerate the column previously in the drying phase.
The compressed air supplied by the dryer has an extremely high quality class and improves
the manufacturing quality and reduces maintenance costs.
Reliability and safety were the major criteria taken into account when designing the PARSEC
series of dryers.
All components have been designed, selected and tested with the utmost care.
The pressure tanks incorporate a fatigue calculation for 10 years of continuous operation
(24/24 - 7/7). They comply with the pressure equipment directive DEP 97/23 and the
application decree of 13 December 1999.
Quite a few dryers are out there on the market, but none comes to the heel of PARSEC, a mature product fruit of a long experience.
The volume of the adsorbers for instance has a a cycle duration far greater than traditional systems, thus saving 18 000 depressurizations per year (on a basis of 8700h). The components last much longer and you save on compressed air.
The mufler are equipped with an anti-burst valve to avoid personal or equipment harm.
The electronic controler aligns dryer and compressor in order to save on precious compressed air.
Each tank is equipped with hoisting-hooks, making its moving easier.
All pieces needing regular maintenance are place in an accessible place.
Each reservoir has openings making filling and draining of the dessicants much easier.
In order to save energy, the dryers are optionally equipped with an energy-saver limiting the compressed air consumption. The regeneration air is thus proportional to to compressed air flow actually consumed by the device.
Outre les économies d’énergies réalisées, cette option permet la visualisation du point de rosée, sa transmission à distance par signal 4...20 mA ainsi qu’une surveillance des paramètres de fonctionnement du sécheur.
Beyond the energy savings, this option makes the dew point visible, remotely transmitted by 4...20 mA signals as well as a parameter monitoring of the dryer parameters.
A "premium" version allows to monitor compressed air pressure and temperature, 2 essential parameters for an optimal functionning and in obtaining the dew point.
A high-tech alarm managing system is integrated into the control module, memorizing the 4000 last events.
