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.
Piping to Vaporizer
The Trifecta Pro 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 Pro 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
Pro Series is a fail-safe device and should
not be relied upon as the only thermal
relief. Operation of the Trifecta Pro Series
“Gas Use” relief device may vent liquid,
creating a noticeable vapor cloud.
The piping and components from the Trifecta Pro 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 Pro 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!
