Italy self-pressurizing liquid nitrogen storage and transportation tank YDZ-175 with movable casters and automatic replenishment

In addition to being used for storage and transportation, liquid nitrogen tanks can also be used for self-pressurizing liquid nitrogen tanks that combine storage and transportation, and are only used for rehydration of other liquid nitrogen containers. The self-pressurizing liquid nitrogen tank belongs to the \"YDZ\" series. It has the same vacuum insulation + internal and external double tank structure as the \"YDS\" series, but the YDZ has no caliber and controls the inlet and outlet of liquid nitrogen through valves.

Features of self-pressurizing liquid nitrogen tank:

1. It is manufactured in accordance with the national standard GB/T 14774-2012, and users have evidence to follow;

2. Both the inner and outer bladders are made of 304 stainless steel, which has strong load-bearing resistance, good low-temper ature resistance and good heat insulation, and is easy to clean;

3. The three valves, boosting valve, venting valve, and liquid inlet and outlet valves, are all low-temperature control valves, which are durable and stable;

4. Equipped with double safety valves and double protection to prevent users from misoperation causing excessive pressure and causing danger;

5. Equipped with a pressure stabilizing system device to stabilize the pressure and liquid nitrogen flow rate to prevent sudden increases and drops in pressure from causing liquid nitrogen to splash and injure people;

6. The movable casters at the bottom are not only flexible, but also have high load-bearing capacity, so you can use them with confidence;

7. Special vacuum technology ensures a low liquid nitrogen evaporation rate;

8. After strict low-temperature testing before leaving the factory, it can enjoy a 5-year vacuum warranty and a 1-year free warranty service;

Advantages of self-pressurizing liquid nitrogen tanks:

1. Low pressure is safer

In addition to self-pressurizing liquid nitrogen tanks, there are also medium and high-pressure Dewar bottles that can realize liquid nitrogen replenishment. The difference lies in the pressure and whether annual inspection is required. The self-pressurizing liquid nitrogen tank has a low pressure within 0.1MPa and has no pressure when not in the infusion state. It is not a pressure vessel and does not require annual inspection, which is safer.

2. High efficiency in outputting liquid nitrogen

Although the pressure is low, the infusion speed of the self-pressurized liquid nitrogen tank is not slow. When it is fully filled, it only takes 20 seconds to pressurize it to the standard pressure; the liquid nitrogen storage capacity is 3/4, which takes about 1 minute. And it relies on the internal pressurization system to pressurize, without contact with external air, and the purity of liquid nitrogen is guaranteed.

In addition, self-pressurizing liquid nitrogen tanks can be equipped with solenoid valves to achieve automatic replenishment.
