Operations Product Manual - Liquid Cylinders
for carbon dioxide at 350 psi / 24.8 bar has a product
weight of 387 pounds / 176 kg).
5
Open the cylinder’s vent and liquid valves. Open the
transfer line shut-off valve to bring the flow of product.
6
If filling CO
2
, adjust the cylinder’s vent valve to
maintain pressure in the cylinder and fill hose. The
equipment must maintain pressures above 70 psi (4.8
bar) during the transfer. Liquid CO
2
will turn into dry
ice at lower pressures.
7
When the scale reads the calculated total filling weight,
turn off the liquid valve on the cylinder Close the vent
valve. It is important to maintain pressure above 70
psi (4.8 bar) if filling CO
2
or N
2
O Do not allow the
cylinder to vent down after filling.
8 Close the transfer line shut-off valve and relieve the
pressure in the transfer line. Remove the transfer line.
Remove the cylinder from the scale
Operating Pressure
The liquid cylinder will automatically maintain a normal
operating pressure between the pressure building portion of
the regulator (300 psi / 20.7 bar) and the economizer portion
of the regulator (325 psi / 22.4 bar). The operating pressure
can be set up or down by simply adjusting the regulator
while watching the pressure gauge. The adjustment range of
the regulator is between 80 and 320 psi (5.5 and 24.1 bar).
The gas delivery pressure should not be confused with the
vessel operating pressure. The delivery pressure should be
adjusted with a separate regulator that is attached to the gas
withdrawal fitting.
Liquid CO
2
Withdrawal
Liquid can be withdrawn from these liquid cylinders in the
same manner that was described in the Dura-Cyl
®
LP Liquid
Cylinder section. However, the transfer of liquid CO
2
is
slightly different and should follow these steps:
1
Connect the transfer hose to the liquid valve fitting of
the high pressure liquid cylinder.
2 Connect the other end of the hose to the receiving
equipment.
3
Open the pressure building valve and wait for the
pressure gauge to reach the operating pressure (300 psi
/ 20.7 bar).
4
Refer to the receiving equipment manual for procedures
to open the fill valve and vent valve of the receiving
equipment.
5
Open the liquid valve on the liquid cylinder. This valve
can be adjusted to obtain the proper liquid flow rate and
delivery pressures.
6
Adjust the receiving equipment vent valve and the
fill valve to maintain pressure in the fill hose. The
equipment and the hose must maintain pressures above
70 psi (4.8 bar) during the transfer. Liquid CO
2
will turn
into dry ice at lower pressures.
7
When the transfer is complete, close the receiving
equipment’s valve. Close the liquid valve on the
cylinder and relieve pressure from the hose.
8 Disconnect or remove the hose from the receiving
equipment.
Caution! The liquid and vent valves on
liquid cylinders should always be
kept closed to protect the inner
vessel and plumbing from being
contaminated.
Gas Withdrawal
The high pressure liquid cylinder will deliver gas at various
flow rates and temperatures for different applications.
The flow rate is controlled by the equipment that is being
supplied gas by the liquid cylinder. The continuous flow rate
indicates the flow rate that will normally provide gas at a
reasonable temperature and should not be exceeded. Higher
flow rates may provide very cold gas that could damage the
equipment attached to them.
To supply gaseous product follow this step by step
procedure:
1
Connect the proper final line regulator to the liquid
cylinder’s gas use outlet.
2
Connect the proper hose between the liquid cylinder gas
use regulator and the receiving equipment.
3
Open the pressure building valve.
4
Allow pressure to build to the operating pressure (300
psi / 20.7 bar).
5
Open the gas use valve.
6
Adjust the gas use regulator for the proper delivery
pressure.
7
When the gas delivery is completed, close all liquid
cylinder valves
Caution! The liquid and vent valves on
an empty liquid cylinder should
always be kept closed to protect
the inner vessel and plumbing
from being contaminated.
Caution! In the Dura-Cyl HP/Cryo-Cyl HP
liquid cylinders the pressure
must be kept above 70 psig for
CO
2
to prevent solidifying the
