Note: It is recommended to insulate the liquid
feed line to minimize fill times and reduce
losses. The fill line (from bulk tank to
Trifecta) length should be limited to 15
total feet (5 meters).
Note: The isolation valve on the bulk tank
liquid line should not be opened until all
plumbing connections are complete.
For earlier versions of the 600 psig Trifecta series, a gas line
from the bulk tank needs to be run to the regulator, which
supplies pneumatic pressure to the actuators on each ball
valve The regulator regulates the pressure from the bulk
tank down to 125 psi The actuators require a minimum of 80
psig The maximum pressure for the gas line is 150 psi
Piping to Vaporizer
The Trifecta XPro Series system does not contain final
vaporization. Consequently, one or more freestanding,
external vaporizer(s) must be connected to the “to Vaporizer”
line of the Trifecta XPro Series The vaporizer(s) should
have a pressure rating of at least 600 psig - or 700 psig for
the 600 psig Trifecta
Note: It is important to make sure the vaporizer
assembly is protected against over
pressurization from trapped liquid. The
vaporizer installation must include a
thermal relief valve just downstream of
the vaporizer, set at 600 psig (or 700 psig
for the 600 psi high pressure Trifecta Gas
Supply System).
Note: The relief device (SRV-3) on the Trifecta
XPro Series is a fail-safe device and
should not be relied upon as the only
thermal relief. Operation of the Trifecta
XPro Series “Gas Use” relief device may
vent liquid, creating a noticeable vapor
cloud.
The piping and components from the Trifecta XPro Series
to the vaporizer must be at least 3/4” (19mm) copper or its
equivalent and of adequate pressure rating Small diameter
lines will introduce undesirable pressure drops and impact
overall system performance The outlet of the vaporizer
should be piped to the customer house line with final line
regulation as required
Note: Installation of an additional purge valve
downstream of the vaporizer is highly
recommended. This valve aids in the
purging of the Trifecta XPro Series and
external vaporizer. This valve will also
serve as an emergency gas feed port.
Note: Ensure that the house line is rated for the
maximum pressure that can be produced
by the Trifecta. Include additional relief
valves and line regulation as required.
Warning! Do not set operating pressure
higher than the lowest relief
device!
