One line version with two compressors:
Two lines version:
It is essential that an air dryer be installed between the compressor and the compressed air receiver. In this way the stored air will
be correctly processed by the air dryer. In any contrary case, the strong demand for air by the concentrator during the pressurisation
phase will not give sufficient time for the air to be treated to extract the maximum of humidity.
It is important to respect the air storage receiver volume so as to be able to respond to the very high peak load air demands by the
concentrator.
It is strongly recommended that a system of continuous air hygrometry monitoring be installed.
Concentrator entry pressure should always be enough to guarantee optimum plant operation. This pressure must never be less than
8 bar.
The concentrator cannot deliver O
2
without the compressor. It is essential that the air production unit is very reliable.
It should be maintained in good working order with serious and qualified personnel carrying out regular maintenance
procedures. The electric power supply must be backed up by a standby generating set.
Note: it is possible to use an air unit made up of a compressor / refrigeration dryer / receiver system. However we would not advise
this, since concentrator working life would be compromised by the resulting condition or low level of cleanliness of the molecular
sieves, not soiled by the oil vapours not retained by the refrigeration dryer.

Regulation
The compressor starts by a call of the concentrator. The operation of the dryer by adsorption either is controlled by the compressor
operation or is controlled by an air hygrometry threshold. (see manual of PROCOM 2).
