Normal start-up
The following key points will op mize daily use:
• Always turn your dryer ON 10 to 15 minutes before the air compressor. This will ensure that the heat
exchanger has been cooled to a proper level to handle the ini al thermal load of the compressed air.
• The NXC cycling refrigerated air dryer has been designed as an energy e ffi cient air dryer and can remain
on even when compressed air produc on has stopped. The electronic regula on will automa cally start
and stop the refrigera on compressor based on the demand on the system. You only need to turn o
ff
your air dryer at night, on the weekend or during system shut down.
• The standard dryer parameters programmed in our factory meet the needs of most applica ons. If
the condi ons in your plant are typical (i.e. not a very hot environment, no par al drying upstream, no
voluntary increase in the dew point...), do not spend me on modifying these parameters.
2.7 use
Only start up the dryer once you have thoroughly tested all the compressed air, refrigera on and
electrical connec ons. !
