Large Liquid Nitrogen Dewar

A 40,000-gallon liquid Nitrogen tank for the Aerospace Industry.

This picture shows a completely insulated stainless steel inner vessel ready for insertion into a carbon steel outer vessel. Note the intricate piping, not unusual for a custom cryogenic vessel.
In this picture, the stainless steel inner vessel is being insulated with reflective, multi-layer insulation. The vessel has previously been cleaned and dried.
In this picture, the stainless steel inner vessel of the 40,000-gallon dewar has been completely wrapped in the multi-layer reflective insulation.
In this picture, the completed dewar (inner and outer vessels) are leaving the Prentex plant for the trip to the customer's West-Coast site. Overall dimensions of the finished vessel are 150 inches diameter and 67 feet, four inches long. Note the 44 wheels on the rig.
