The flow performance depends on the ability of the total
system to:
• Build pressure in the transfer tanks using gravity and
ambient coils
– Proper air flow and sunlight reaching the pressure
building coils
– Extreme weather conditions, and/or duty cycles, may
require de-icing of the pressure building system or the
addition of higher capacity vaporizers
• Vaporize liquid into gas to maintain pressure and flow at
the use point
– The vaporizer must be sized for the geographical
location, flow/pressure requirements and duty cycle.
– Less than optimum sun light and air flows across the
coils will reduce the performance
• Fill times - refilling the reserve tank from the bulk tank
prior to the primary tank emptying
– The overall flow rate of the system can be limited by
the systems ability to refill. Flow out cannot exceed
flow in!
– Special care must be given in selection of the bulk
tank that supplies the Trifecta
– The tanks heat leak performance is critical in
transferring cryogen in the liquid state to the Trifecta
– Liquid use lines and valves out of the bulk tank must
be sized properly Small restrictive liquid lines and
valves will increase fill times and increase losses.
– The pressure building system of the bulk tank
needs to be sized to build tank sub-cool The sub-
cool condition (pressure above the liquid saturation
pressure) helps keep flow rates up and the cryogen in
the liquid state as it travels to the Trifecta
– Liquid feed lines from the bulk tank to the Trifecta
must be kept as short as possible. Longer liquid fill
lines will lead to longer fill times and additional
losses Take great care in laying out your Trifecta
system Insulating the liquid feed line will reduce its
effective length resulting in decreased fill times and
reduced losses
