How to safely, efficiently, and conveniently supplement and transfer liquid nitrogen in biological sample banks, medical institutions, research laboratories, and industrial production is a key challenge.Self pressurized liquid nitrogen tankThrough internal pressurization design, automatic output of liquid nitrogen has been achieved, changing the traditional mode of relying on manual handling and dumping, making it an ideal solution for modern liquid nitrogen management.

The core advantage of liquid nitrogen tanks lies in their "automatic pressurization and pipeline transportation". The device establishes a stable and controllable pressure inside the tank through a built-in pressurization system (usually using ambient heat or an electric heater to heat the evaporator), and uses the pressure difference to continuously and smoothly press liquid nitrogen out through the pipeline, making it easy to remotely replenish other containers or directly cool down the device.

1. Efficient and convenient transportation, labor-saving and safe

No need for manual handling of heavy liquid nitrogen tanks for pouring, simply connect pipes and valves to achieve one click liquid discharge. This greatly reduces labor intensity and avoids safety risks such as frostbite and spills that may occur during manual operations, especially suitable for transferring liquid between large liquid nitrogen tanks or replenishing liquid nitrogen to high-altitude containers.

2. Stable and controllable liquid output, adjustable flow rate

The output pressure can be precisely controlled through a precision pressure regulating valve, thereby achieving stable and continuous liquid nitrogen outflow. Users can adjust the flow rate as needed to achieve fine flow replenishment or rapid filling, effectively reducing the volatilization loss of liquid nitrogen caused by severe boiling during the transfer process, and achieving higher utilization efficiency.

3. Large capacity design ensures continuous supply

Self pressurized liquid nitrogen tanks typically have large capacities, ranging from 30 liters to 100 liters or even larger, capable of storing sufficient liquid nitrogen to meet long-term, large-scale supply needs. Its design fully considers the cold insulation performance, with low static evaporation loss rate, ensuring that liquid nitrogen can be stored stably for a long time.

4. Multi functional integration, widely used

Tank bodies are usually equipped with various devices such as level gauges, pressure gauges, safety valves, and vent valves, which facilitate real-time monitoring of the status inside the tank and ensure operational safety. It is not only used to supplement other Duwa tanks, but also directly provides low-temperature cooling medium for low-temperature crushing equipment, freeze dryers, bioreactors, etc.

The self pressurized liquid nitrogen tank, with its outstanding features of intelligence, high efficiency, and safety, solves the problem of large-scale liquid nitrogen transportation. It is a landmark equipment that enhances the automation level of liquid nitrogen management in laboratories, biological sample banks, or factories, and is a powerful backing for achieving efficient and safe low-temperature work.
