The self-pressurized series liquid nitrogen tanks are used for transporting and storing low-temperature liquid nitrogen. They are high-performance containers made from high-quality stainless steel. These tanks utilize an internal pressurization system to vaporize a small amount of liquid nitrogen, generating pressure that expels the stored liquid nitrogen from inside the container. The self-pressurized series liquid nitrogen tanks consist of control components and the tank body. Key control components include inlet/outlet valves, vent valves, pressurization valves, safety valves, level gauges, pressure gauges, and swivel casters. All models in this series are equipped with four swivel casters for easy movement and usage in various locations.

These tanks are widely used in industries and fields such as mold manufacturing, animal husbandry, pharmaceuticals, semiconductors, food processing, aerospace, military, and low-temperature chemical engineering.
