Product Introduction
Liquid nitrogen thermal insulating cryogenic dewars are mainly used for storing and transporting liquid nitrogen, liquid oxygen, liquid argon, and can automatically provide continuous gas. Cylinders are designed as high vacuum multi-layer winding insulation structure, the liner is used to store cryogenic liquid, the outer wall is wrapped with multi-layer insulation material, so as to get superior thermal insulation properties. At the same time, the sandwich (between the two layers of container) is evacuated into a high vacuum to form a good adiabatic system.
