PDp filter (Only for ZR/ZT 110-145)
The high efficiency particle filter for dust protection PDp makes sure no dust particles with size above 0.01
µm enter the air net.
PDP sensor (Only for ZR/ZT 110-145)
The pressure dewpoint of the compressed air leaving the IMD dryer is continuously shown on the display
of the Elektronikon regulator. This allows to monitor the performance of the dryer and to make sure that
the compressed air is dry enough for the application.
Silicon-free rotor
With this option, the compressed air leaving the compressor is 100 % silicon-free.
Low load compensator for IMD dryer
When the compressor is frequently loading and unloading and when the load/unload cycles are short, the
rotor of the IMD will not be properly regenerated. This will lead to an increase of the pressure dewpoint
and a reduced lifetime of the rotor. The option low load compensator will make sure that the rotor is always
regenerated properly ensuring a good IMD performance and a long rotor lifetime.
Dryer by-pass
The dryer by-pass enables to use optional air piping to avoid air flow through the dryer. It is NOT allowed
to service the dryer when it is by-passed and the compressor is running!
Kit for purge of dry air during standstill
When frequent and long standstills occur, it is recommended to install a kit for purge of dry air to guarantee
the life time of the oil-free screw elements. During standstill, condensation (which triggers corrosion)
might occur. This results in an expected element lifetime reduction or even a compressor stage blocking
during standstill. Condensation is prevented by blowing a small amount of dry air through the small gap
between rotor-rotor and rotor-housing once the compressor is stopped. To avoid long standstills, regular
starting can be programmed in the Elektronikon controller or by a central Atlas Copco ES controller.
Oversized motor
The size of the motor is chosen in such a way that the Service Factor of the motor is never used.
SMARTBOX
When ordering the compressor, it is possible (except for Japan and Korea) to choose the free SMART BOX
option which is mounted in the electrical cabinet. The SMART BOX allows read-out of the compressor
parameters on a login-protected web site called SMART LINK. The connected antenna is mounted on the
outside of the electrical cabinet. (Refer to the SMARTBOX and SMARTLINK section.)
