OPERATION OF DURA-CYL 160 / 180 / 200 / 230 / 265 MP
34
Operating Pressure
The liquid cylinder will automatically maintain a nor-
mal operating pressure between the pressure
building portion of the LCCM (125 psi/ 8.6 BAR) and
the economizer portion of the LCCM (140 psi/ 9.7
BAR). The operating pressure can be set up or down
by simply adjusting the LCCM control knob (item B)
while watching the pressure gauge. The adjustment
range of the regulators is between 40 and 160 psi
(2.8 and 11.0 BAR).
The gas delivery pressure should not be confused
with the vessel operating pressure. The delivery
pressure should be adjusted with a separate regula-
tor that is attached to the gas withdrawal fitting.
Gas Withdrawal
The liquid cylinder will deliver gas at various flow
rates and temperatures (as shown in Figure J1,
page 13) for different applications. The flow rate is
controlled by the equipment that is being supplied
from the liquid cylinder. The continuous flow rate (as
shown in the specification, pages 14-16) indicates
the flow rate that will normally provide gas at a rea-
sonable 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 fill line regulator to the liq-
uid cylinder's gas use outlet (Item 108).
2. Connect the proper hose between the final line
regulator and the receiving equipment.
3. Open the pressure building valve (Item A).
4. Allow pressure (refer to gauge – Item 94)
to build to the operating pressure (125 psi-
8.6 BAR).
5. Open the gas use valve (Item 105).
6. Adjust the gas use regulator for the proper de-
livery 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.
Service and Maintenance
Refer to section 15 and 16 of this manual to trouble
shoot problem, and service these liquid cylinders.
