Withdrawing Liquid From The Container
To use the container in liquid delivery service, attach a transfer hose to the LIQUID
connection and open the adjacent LIQUID valve. The pressure in the container will
drive liquid product out through the valve as long as the container pressure exceeds
trhat of the receiver.
The rate of liquid withdrawal from these containers is variable depending on teh
container pressure and the saturation temperature of the liquid. With liquid saturated
at 22 psig (1.5 bar/152 kPa) withdrawal rate of up to 6 liters/min can be obtained.

Filling the Container
Cryogenic liquid containers that operate below 25 psig (1.7 bar/172 kPa) may be filled
by weight or by volume. The latter method depends on the filler observing liquid
product exiting the vent valve as an indication that the container is full. Both methods
are listed here. Be certain to observe all safety precautions associated with the
handling of cryogenic liquids.
Filling the Container by Weight of Contents
Using the procedures below, first determine the proper filled weight of each container.
The weight derived is then used in the filling procedure that follows.
1. Visually inspect the container. Do not attempt to fill containers that have broken or
missing components.
2. Move the container to a filling station scale and weigh it both with, and without,
the fill hose attached to determine the weight of the fill line assembly. The differ-
ence is the fill line weight.
3. To determine the weight at which the fill should be stopped, add the desired filling
weight, the transfer line weight, and the Tare Weight from the container’s data
plate.
4. Once you have determined the proper fill weight for the container, connect a
transfer hose to the LIQUID fitting from a low pressure sources of liquid.
5. Open the supply valve. Then, on the XL-160/XL-180, open the LIQUID and VENT
valves to begin the fill.
6. During the fill, monitor the container pressure and maintain a pressure of 10-15
psig (0.7 bar/69-103 kPa) by throttling the VENT valve.
7. When full weight is reached, close both the LIQUID and the VENT valves.
8. Close the liquid supply valve and open the dump valve on the fill line assembly.
9. Disconnect the fill line from the container and remove the container from the scale.
CAUTION:
To avoid contamination, close
the LIQUID valve before dis-
connecting the transfer line.
WARNING:
Filling operations should take
place only in well ventilated
areas. Accumulations of
product gas can be very danger-
ous (refer to the safety precau-
tions in the front of these
instructions). Maintain ad-
equate ventilation at all times.
NOTE:
The fill weight calculation
inlcudes the weight of residual
liquid. the weights shown in the
Specifications are for liquid
saturated at atmospheric pres-
sure. The actual fill weight for
your applaction depends on the
saturation temperature of liquid
in your storage tank, and mayh
be determined by weighing
cylinders that have been filled by
volume.
