Taylor-Wharton XL-65HP (with dual regulators) - Manual (Page 8)

WITHDRAWING GAS FROM THE CONTAINER
To withdraw gas from the XL-65/65HP connect a suitable pressure regulator to the USE
connection, and the output of the regulator to your external equipment. Then open the
USE and the PRESSURE BUILDING valves. When the container pressure reaches 125
psig (8.6 bar/862 kPa) for the XL-65, —or 300 psig (20.7 bar/2069 kPa) for the XL-65HP –
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-65/65HP can supply gas flow rates up to 350 cfh @NTP (9.2
cu.m/h @ STP) using only its internal vaporizer. At low rates, the gas supplied will be at
near ambient temperatures. As the flow demand is increased, the gas will become propor-
tionately colder. If greater vaporizing capacity is required, an accessory external vaporizer
is available. When an external vaporizer is used, it must be connected to the USE valve
and the regulator moved to the output of the external vaporizer.
WITHDRAWING LIQUID FROM THE CONTAINER
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 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.
