Guinea-Bissaupressurized Liquid Nitrogen Dewar Ln2 Dewar Liquid Phase Storage

The storage and supply of liquid nitrogen are critical in high-end fields such as biological sample banks, medical cold storage, and scientific research laboratories. For these industries, the YDS series liquid nitrogen tanks provide reliable storage, while the supply requires self-pressurized liquid nitrogen tanks to ensure continuous and stable operations.

Self-pressurized liquid nitrogen tanks come in capacities ranging from 15 to 500 liters, with the 175-liter tank being especially popular in laboratories and superconducting applications. The 175-liter self-pressurized liquid nitrogen tank is equipped with a multi-stage safety system, including double safety valves and pressure stabilization features, ensuring secure and efficient liquid nitrogen supply.

This self-pressurized tank is particularly well-suited for liquid nitrogen supply in sample libraries, sperm banks, stem cell banks, and laboratories that require large-capacity tanks for replenishment or superconductivity purposes.

• Ultra-Large Capacity Storage: The 175-liter tank has a geometric volume of 185 liters, with an effective liquid nitrogen storage volume of 175 liters. This ample capacity ensures that large sample banks have sufficient nitrogen reserves, meeting the high-demand storage requirements.

• Self-Boosting Design: The tank utilizes the pressure generated by the vaporization of liquid nitrogen to automatically discharge liquid nitrogen, ensuring a continuous and stable supply. With a stable working pressure of less than 0.09 MPa, this design ensures reliability and ease of use.

• Safety Technology: The tank is equipped with double safety valves, providing two layers of safety protection. Additionally, it can be configured with a low-temperature solenoid valve for fully automated liquid replenishment, offering convenience and safety for high-demand applications.

• Low Daily Evaporation Loss: The tank adopts advanced vacuum technology to minimize evaporation loss, ensuring long-term preservation of liquid nitrogen, which is crucial for maintaining the quality and integrity of stored biological samples.

• Humanized Caster Design: The tank features high-load capacity mobile casters, allowing for easy mobility in laboratories and facilities. This design is especially beneficial for frequent movement and repositioning of large tanks.

• Production Process: All welds are rigorously tested using helium mass spectrometer leakage detection, and 100% low-temperature testing is performed to guarantee the tank's reliability and performance under extreme conditions.

• Production Materials: Constructed with high-quality 304 low-temperature-resistant stainless steel, this tank ensures durability and long-term service life, even in harsh low-temperature environments.

• Safe Filling Recommendations: To avoid overfilling and ensure safe operation, it is recommended to fill the tank up to 90% of its geometric volume. This reserved space is essential for maintaining sufficient vaporization pressure and preventing potential risks associated with overfilling.
