properly set up prior to set up of the CryoDoser FleX.
Refer to the Phase Separator Product Manual for specific
instructions
If the CryoDoser FleX system is being fed liquid nitrogen
from the Chart Dura-Cyl cylinder, ensure the connection
hose to the CryoDoser FleX has been properly connected
including the installation of a safety relief device as part
of the hose installation, that the stainless steel filter has
been installed in the end of the hose bayonet, and that the
bayonet connection to the CryoDoser FleX has been properly
installed and secured
Manually open (counter clockwise) the blue handle valve on
the Dura-Cyl liquid cylinder.
Refer to the CryoDoser FleX Controller Quick Start Guide
for additional information
System Shut Down
1 Manually close (clockwise) the Y-Pattern valve (blue
handle).
2 Manually open (clockwise) the ball valve (yellow
handle) on the Purge Kit.
Note: The supply pressure reading on the FleX
controller may read 12 ± psi due to the
added GN

pressure.
Also, refer to the phase separator product manual for
instructions regarding shutting down of the phase separator if
applicable.
If your CryoDoser FleX system is being fed off of a Chart
Dura-Cyl liquid cylinder close (clockwise) the valve of the
cylinder
Best Practices for Superb Operation
Minimize the entry of moisture into the
dosing system
1 Moisture turns into ice when subjected to cryogenic
temperatures. Ice causes blockages and can lead to
tremendous down time Moisture can inadvertently
enter the dosing system in various ways including
splashing product, system cleaning, or from the
environment. It is extremely important to be aware of
this and prevent moisture from entering or accumulating
in the dosing system.
2 How can moisture be prevented from entering the
dosing system?
a When not in use, or being cleaned, cap the vent and
the dosing head area.
b If the system will not be used for a short period
of time it is helpful to keep some liquid in the
dosing body to provide positive pressure at the vent
preventing moisture from creeping in.
Nozzle use
Standard nozzles are single opening devices with diameters
ranging from 0.020” to 0.110” in 0.005” increments. In
addition to these devices, Chart provides a range of specialty
nozzles in our “Soft Dose” packages. These nozzles include:
Ventilator, Regar, Diverging, Converging, Angle and Hot
Chute.
• Where to use - There is no set standard that identifies
a specific nozzle for a product. Each product, product
line, and requirement will lead towards defining the
type of nozzle(s) used. In general, standard single
opening nozzles are used in the vast majority of
liquids; such as water, teas, coffees and beers. They
are also used with dry goods such as peanuts and
almonds. The same nozzles can be used for both
pressurization or inerting (oxygen reduction).
• Soft dose nozzles may also be used for pressurization
or inerting. The use of these nozzles may provide
added benefits such as less spray for products that
can tend to be ejected from their container if a single
hole nozzle is used. Powder or granulated products
such as ground spices, ground coffee, teas, or even
baby formula are examples of susceptible products.
• Soft dose nozzles such as the “Regar” nozzle have a
shower head spray pattern that can be used to diffuse
slightly to minimize product ejection. In addition,
this particular nozzle has a wide spray pattern
making it suitable for larger opening containers.
• The Hot Chute is a unique soft dose product.
This device utilizes a standard nozzle but also
incorporates a set of heating elements and nose
extension allowing access to some locations where a
standard dosing head may not be able to reach into a
small space. The added heating elements diffuse the
nitrogen stream causing it to become more of a mist
which also minimizes product expulsion.
Sensors
The Chart dosing systems typically utilize three sensors for
high speed operation. Lower speed lines or manual operated
lines can operate on just one sensor.
