XPro Series
Installation Procedure
The installation of the Trifecta XPro Series should be done in
the following order:
1 Place Trifecta XPro Series Skid on concrete pad next
to bulk tank — concrete pad specifications should be in
conformance with local building codes and reviewed by
a licensed engineer
2 Pipe Trifecta XPro Series liquid fill line to bulk tank
labeled “From Bulk Tank ”
a Use liquid withdrawal line on bulk tank
Note: Do not use the dip tube line.
3 Pipe Trifecta XPro Series gas use line to external
vaporizer labeled “To Vaporizer ”
4 Connect power supply to dedicated 120V AC, 15 amp
circuit
Note: For older style 600 psig XPro units
equipped with pneumatic actuated ball
valves, a nitrogen gas line coming off the
vapor space of the tank will need to be
run to the Trifecta.
5 Commission Trifecta XPro Series System
Placement of Trifecta XPro Series
Skid
The Trifecta XPro Series skid has four lifting lugs on the top
of the skid These lifting lugs allow for placement of the skid
by overhead crane. If an overhead crane is not available, the
skid has fork truck access as well
Note:
The Trifecta XPro Series assembly weighs
almost 1900 lbs. empty (864 kg).
The Trifecta XPro Series skid should be placed on the
concrete pad near the bulk storage tank as seen in the
Introduction portion of this manual The skid should
be placed as close to the bulk tank as possible without
interfering with any other equipment or service requirements
of the tank The system requires a transfer of liquid and gas
between the bulk storage tank and the Trifecta XPro Series
skid. This process becomes less efficient with increasing
transfer line length
Note: Each site may have unique requirements;
however, it is recommended to follow the
basic layout located in the Introduction
section of this manual.
The skid should also be placed such that there is easy access
to all sides of the unit The skid should be placed where it
may receive a maximum amount of sunlight and airflow. One
must be able to check the individual cylinder gauges, the
control box, and any of the solenoid valves or transmitters at
any time Consideration should also be given to the external
vaporizer placement on the concrete pad
Note: It is important that the sun and wind
contact both the external vaporizer and
pressure build coils inside the skid to
insure optimal operation of the unit and
prevent unusual buildup of ice.
Note: Do not locate the Trifecta or Vaporizer
near equipment that produces excessive
moisture (i.e. cooling towers, drains, etc.).
Liquid Line Piping to Bulk Tank
The Trifecta XPro Series skid requires a liquid line piped
from the bulk storage tank This line will serve two
functions. First, to allow the high pressure gas to return to
the liquid side of the bulk tank (reduce losses), second, to
allow the transfer of liquid from the bulk tank to the Trifecta
By removing the tube connection between A and B — shown
in Fig 1 on next page — the high-pressure vent gas can be
separately piped to the gas phase of the bulk tank, or totally
vented to atmosphere Venting the Trifecta to the gas phase is
often useful when connecting multiple Trifectas to one bulk
tank
The backside (PB Side) of the XPro Series skid has two/three
connection points
• Connection (A) serves as both the high pressure gas
outlet and the liquid inlet when the tubing connection
between A and B is in place
• Connection (B) is the high pressure gas outlet when the
tubing connector between A and B has been removed
• Connection (C) is the high pressure liquid outlet to the
process vaporizers
