Tank as possible. Maximum tubing length should not
exceed 4.5 meters with the tubing size maintained as
indicated in this manual. If longer tubing lengths are
required consult YZ Systems Technical Services at;
800.653.9435 or 1.281.362.6500.

Note: In applications where the actuation gas supply
has a high water content and/or a low hydrocarbon dew
point, additional actuation gas ltration or heating of the
NJEX system may be necessary. Bottled nitrogen can
also be used during cold operating conditions to avoid
condensation in the actuation gas supply line. Also,
an actuation gas source pressure of 5.2 Bar should be
adequate in most installations.
