Liquid Nitrogen Storage
Photo 10 - Liquid Nitrogen Filter
Photo 9 - Liquid Nitrogen Tank
A 3,000 gallon liquid nitrogen tank provides pre-cooling
to the refrigerator and cooling to the thermal shield in
the 1500 liter helium dewar. The LN2 tank is connected
to the cryogenic test area by a vacuum insulated
transfer line. The nitrogen gas is used for instrument
air and also available for pump down and purge of
insulating vacuum spaces.
In Photo 9, the liquid nitrogen vaporizer can be seen
mounted to the liquid nitrogen tank.
In Photo 10, the vacuum jacketed liquid nitrogen filter
is used to remove moisture introduced by supplier during
liquid nitrogen filling of the storage tank.
The liquid nitrogen fill pedestal, seen in Photo 11, is
located at the curb side for ease of refilling. Photo 12
shows the liquid nitrogen pedestal located at the liquid
nitrogen tank.
