condensation happens when air passes over a surface which is below the air's
dew point.  it's more likely that the main chiller's cold output will be 
at a lower temperature than the door coil, so any condensation will happen
there.  that's assuming you don't have oddities like major moisture sources,
and that you avoid undesirable airflow.
