The XL-45HP will store up to 165 liters of product; the XL 50HP/50VHP up to 176 liters,

and 196 liters for the XL-55HP. All four cylinders can deliver either liquid or gas. The

following component and circuit descriptions are pertinent to the operation of all the con-

tainers and should be read before attempting operation. The components may be identi-

fied on the Component Location Illustration.

Internal Vaporizer  A liquid container for gas service must have an internal heat ex-

changer that functions as a gas vaporizer coil to convert liquid product to gas continu-

ously during withdrawal. The XL-45HP/50HP/55HP/50VHP utilize an internal heat ex-

changer that is inside the vacuum space attached to the containers outer casing. It

provides a mean of introducing heat from outside the containers insulated jacket, to

vaporize liquid as gaseous product is withdrawn. The capacity of this circuit is sufficient to

vaporize at flow rates up to 350 cfh @ NTP (9.2 cu.m/h @STP). If a greater continuous

demand is put on the vaporizer, an external vaporizer should be added to properly warm

the gas and avoid malfunction, or damage, to gas regulators, hoses, and other down-

stream components.

Pressure Building  A Pressure Building circuit is used to ensure sufficient driving pres-

sure during high withdrawal periods. This function is actuated by opening a hand valve that

creates a path from the liquid in the bottom of the container, through the Pressure Building

Regulator, to the gas space in the top. When the pressure building valve is open, and the

container pressure is below the pressure building regulator setting, liquid taken from the
