Taylor-Wharton XL-55HP (with dual regulators) - Manual (Page 8)

WITHDRAWING GAS FROM THE CONTAINER
To withdraw gas from the XL-45HP/50HP/55HP/50VHP connect a suitable pressure regu-
lator to the USE connection, and the output of the regulator to your external equipment.
Then open the USE connection, and the output of the regulator to your external equip-
ment. Then open the USE and the PRESSURE BUILDING valves. When the container
pressure reaches 125 psig (8.6 bar/862 kPa), 300 psig (20.7 bar/2068 kPa) or 400 psig
(28 bar/2758 kPa) if equipped with the higher valve Dual Pressure Building/Economizer
regulator – set the pressure regulator for the desired delivery pressure.
Increasing Gas Supply Capacity – Two or more liquid containers may be manifolded
together. Accessory manifolds are available for use in creating a higher capacity gas
supply system. The XL-45HP/50HP/55HP/50VHP can supply gas at flow rates 1 up to
350 cfh @ NTP (9.2 cu. m/h @ STP) using only its internal vaporizer. At low flow rates, the
gas supplied will be at near ambient temperature. As the flow demand is increased, the
gas will become proportionately colder. If greater vaporizing capacity is required, an ac-
cessory external vaporizer is available. When an external vaporizer is sued, it must be
connected to the USE valve and the regulator moved to the output of the external vapor-
izer.
WITHDRAWING LIQUID FROM THE CONTAINER
When a container is used to supply liquid product, such as in an application as portable
distribution container for carbon dioxide, liquid may be withdrawn from the XL-45HP/50HP/
55HP/50VHP.
Attach a transfer hose to the LIQUID connection and open the adjacent LIQUID valve. The
presser in the container will drive liquid product out through the valve as the container
pressure exceeds that of the receiver.
The rate of liquid withdrawal from these containers is variable depending on the gas phase
pressure and the saturation temperature of the liquid.

are
subject to the
formation of dry ice if
excessively cold gas
or high flow rates are
used. If this condition
occurs, an external
vaporizer should be
used to ensure the gas
is warmed before it
reaches the regulator.
