Features
The MVE cryogenic liquid cylinders were designed to furnish a
convenient, reliable, and economical method for the transportation and
delivery of liquefied gases.
Important features of these liquid cylinders include:
* The Cryo-Cyl Series liquid cylinders are constructed with an all
stainless steel internal support system designed for low heat leak and
high strength.
*
These cylinders are easily handled by one person.
* Gas stored in liquid form in a Cryo-Cyl Series liquid cylinder is more
pure than gas stored in conventional cylinders.
* During periods of non-use, pressure will rise in a cryogenic liquid
cylinder. The highly efficient insulation system minimizes the rate of
pressure rise. This allows for a reasonable period of non-use without
any venting of product from the pressure relief valve.
* Internal pressure building and vaporization systems permit a
continuous flow of gas without need for an external vaporizer.
* The pressure control regulator automatically maintains working
pressure with minimum product loss.
* Cylinders can be used singularly or can be manifolded to provide a
continuous gas supply.
The performance of a liquid cylinder can be shown in its ability to hold a
cryogenic liquid and dispense it as a gas.
The normal evaporation rate (NER) is an indication of how well the
insulation system performs its ability to hold cryogenic liquid. The Cryo-
Cyl Series NER is shown in the Specifications chart.
The pressure building system can be measured by how fast it can increase
pressure in the liquid cylinder and how well it maintains pressure while gas
is being withdrawn from the cylinder.
The performance of the vaporizer to convert cold liquid into gas is shown
by how the outlet gas temperature drops as the gas flow rate increases.
