Overview:

Self-pressurizedliquid nitrogen tank produces pressure by evaporation of littleliquid nitrogen so that liquid nitrogen will exhaust itself andcomplement other containers. It finds its application in thetransportation and storage of liquid medium (liquid nitrogen,liquid oxygen and liquid argon) and cold source of otherrefrigeration equipments. It is now widely used in tool and dieindustry, animal husbandry, medicine, semi-conductor, food,cryogenic chemical industry, aerospace, military and otherindustries and areas. (Dewar flask, dewars, dewar, etc)

ProductionMaterials:

Inner and outercylinders of the main body are made up of 304 austenite cryogenicspecial stainless steel of fine quality; absorbers are regeneratedand activated; multi-layer insulation materials areoil-and-lipid-free thin imported composite.

ProductionTechnology:

All weld joints aretested by helium mass spectrometer; 100% of products have gonethrough strict cryogenic examination; unique patentedvacuum-pumping technology ensures extremely evaporation loss rate;optional machine or digital display liquid level gauge; containershell makes use of unique polishing technology and has aestheticmodeling; the entire production process strictly followsIS9001:2008 standards.

SecurityTechnology:

A two-way multi-layersecurity system is installed to ensure safety for production use;layout of the safety valve, outlet valve, vent valve, and boostervalve is reasonable for secure and convenient operation.
