In short pipelines, it is always convenient to install a reservoir with at least 1/5 of the compressed air volume produced by the compressor
(measure the flow in liters/minute for the installed compressor). It is strongly recommended to install the reservoir before the Air Dryer to
avoid flooding the dryer from the condensed water coming from the air compressor, which can overload the operating capacity of the equi-
pment.
In a good compressed air network project, it requires the installation of a reservoir/condensate separator to absorb the pulsations generated
through sudden consumption and strategically maintain a reserve supply to protect against consumption peaks.
We recommend installing in the compressor outlet or in the compressed air line, a derivation with a hose and spray nozzle for cleaning the
condenser and other maintenance jobs required as the need arises at the compressed air installation site.
4.1 Connection to the compressed air system
The user is responsible to ensure that the dryer will never be operated with pressure exceeding the maximum pressure rating on
the unit data tag.
Over-pressurizing the dryer could be dangerous for both the operator and the unit.
The air temperature and the flow entering the dryer must comply within the limits stated on the data nameplate. The system connecting
piping must be kept free from dust, rust, chips and other impurities, and must be consistent with the flow-rate of the dryer. In case of tre-
atment of air at particularly high temperature, the installation of a final refrigerator could result necessary. In order to perform maintenance
operations, it is recommended to install a dryer by-pass system.
In case of heavily polluted inlet air (ISO 8573.1 class 3.-.3 or worse quality), we recommend the additional installation of a pre-filter
(5 micron minimum) to prevent a clogging of the heat exchanger.
In realising the dryer, particular measures have been taken in order to limit the vibration which could occur during the operation. Therefore
we recommend to use connecting pipes able to insulate the dryer from possible vibrations originating from the line (flexible hoses, vibration
damping fittings, etc.).
