Pressure Building Liquid Nitrogen Container
Pressure building liquid nitrogen container (Dewar) generates pressure by evaporation of a small amount of liquid nitrogen, so that the container can discharge liquid nitrogen automatically, and supply liquid nitrogen for other containers. It finds its application in the transportation and storage of liquid medium and cold source of other refrigeration equipments. It is now widely used in tool and die industry, animal husbandry, medicine, semiconductor, food, cryogenic chemical industry, aerospace, military and other industries and areas.
