Self-pressurized Liquid Nitrogen Tank YDZ-500

Liquid nitrogen supplement series liquid nitrogen tank
The self-pressurized liquid nitrogen tank uses a small amount of liquid nitrogen in the tank to vaporize to generate pressure, so that the container can automatically discharge liquid nitrogen, so as to supplement liquid nitrogen for other containers. It is mainly used for the transportation and storage of liquid media, and can also be used as a cold source for other refrigeration devices. It can be equipped with liquid nitrogen tank monitoring terminal and monitoring software, which can realize the remote transmission of liquid nitrogen liquid level, pressure and other data, realize low liquid level, overpressure remote alarm, and manual remote pressurization and control liquid replenishment.

At present, it is used in mold industry, animal husbandry, medicine, semiconductor, food, low-temperature chemical industry, aerospace, military and other industries.

| Core Advantages

Integrated Self-Pressurization System

The built-in self-pressurization system of the YDZ-500 liquid nitrogen tank automatically adjusts internal pressure to achieve stable liquid discharge, ensuring continuous and efficient supply of liquid nitrogen. This design simplifies operation processes, reduces labor costs, and avoids potential safety hazards caused by manual operation, perfectly meeting the needs of large-scale liquid nitrogen use.

Superior Insulation & Low Evaporation Rate

Equipped with high-vacuum multi-layer insulation technology, the YDZ-500 self-pressurized liquid nitrogen container effectively blocks heat transfer, reducing the daily evaporation rate to only 1.10%. Compared with ordinary liquid nitrogen tanks, it extends the storage time of liquid nitrogen significantly, lowering the overall use cost for users while ensuring the stability of low-temperature environment (-196°C) for stored items.

Flexible Mobility & Stable Structure

TheYDZ-500 500L liquid nitrogen tank is equipped with high-quality braking casters, allowing easy movement and fixed positioning in laboratories, workshops, and farms. The sturdy stainless steel structure ensures excellent impact resistance and corrosion resistance, adapting to complex working environments. Its reasonable size design balances storage capacity and space occupation, facilitating daily placement and maintenance.
