50liter ln2 Self-pressurized container dewar Overview: Self-pressurized liquid nitrogen tank produces pressure by evaporation of little liquid nitrogen so that liquid nitrogen will exhaust itself and complement other containers. It finds its application in the transportation and storage of liquid medium liquid nitrogen and cold source of other refrigeration equipments.

ln2 Self-pressurized container dewar  is now widely used in tool and die industry, animal husbandry, medicine, semi-conductor, food, cryogenic chemical industry, aerospace, military and other industries and areas. (Dewar flask, dewars, dewar, etc) Production Materials: Inner and outer cylinders of the main body are made up of 304 austenite cryogenic special stainless steel of fine quality; absorbers are regenerated and activated; multi-layer insulation materials are oil-and-lipid-free thin imported composite. Production Technology: All weld joints are tested by helium mass spectrometer; 100% of products have gone through strict cryogenic examination; unique patented vacuum-pumping technology ensures extremely evaporation loss rate; optional machine or digital display liquid level gauge; container shell makes use of unique polishing technology and has aesthetic modeling;

ln2 Self-pressurized container dewar Security Technology: A two-way multi-layer security system is installed to ensure safety for production use; layout of the safety valve, outlet valve, vent valve, and booster valve is reasonable for secure and convenient operation.
