Why is a liquid nitrogen storage tank important?
This is particularly important with liquid nitrogen storage tanks as liquid air can condense causing oxygen enrichment and metal embrittlement of the outer jacket and support structure. 2. LAYOUT OF THE INSTALLATION
How does a nitrogen tank work?
The tank is usually fitted with a dispense pipeline system to dispense the nitrogen in either liquid or gaseous form (or both) to the end use applications (e.g. cold storage). Liquid dispense pipelines are always insulated to reduce product losses caused by vaporisation of the liquid.
What is a liquid nitrogen storage & supply facility?
Liquid nitrogen storage and supply facilities, within life science applications, must therefore be planned, with the health and safety of laboratory, delivery, maintenance and other personnel paramount. Scientific processes require the use of liquid nitrogen in a number of applications.
