  1. Liquid valve (inlet/drain): When filling the container through the inlet/drain valve, first open the vent valve, connect the metal hose for infusion to the inlet/drain valve, and open the Inlet/drain Valve. That is, you can add liquid media through the inlet/drain valve. After filling, close the inlet/drain valve.
  2. Liquid level gauge: By observing the yellow indicator ring in the transparent display, the changes can be directly read in the liquid level.
  3. Storage: When you use this container to store liquid nitrogen, please close the inlet/drain valves and pressurization valves, and must open the vent valve.
  4. Transportation: When you use this container to transport liquid media, the opening and closing status of each valve should be the same as during storage. Please fix the container seat with the wheels under it, and use a rope to securely secure the container to the vehicle.
  5. Infusion: Close the vent valve, open the booster valve, and observe the pressure gauge. When the pressure rises to 0.05MPa (0.5kg/cm2), open the drain valve, which allows continuous infusion.
Self pressurized liquid nitrogen container


  1. Replenish liquid nitrogen.
    Self-pressurized liquid nitrogen tanks can replenish liquid nitrogen for larger liquid nitrogen containers, such as large storage and transportation liquid nitrogen tanks. The entire process is automated and requires no manual operation, making it very convenient.
  2. Widely used in modern low-temperature clinical surgery operation and other medical industries. Self-pressurized liquid nitrogen tanks have been widely used in the medical industry. It can be paired with cryotherapy equipment to replace most surgeries in traditional clinical departments. It is safe, painless, and has good therapeutic effects.
