The diameter of yds-20 liquid nitrogen tank is 50mm, which is larger than 10L and lighter than 30L. Herdsmen and farmers can choose specifications according to their actual needs.

Technical parameters of yds-20 liquid nitrogen tank:

1. Model: yds-20

2. Geometric volume: 20L

3. Empty weight: 9.5kg

4. Caliber: 50mm

5. Outer diameter: 365mm

6. Height: 610mm

7. Static liquid storage period: 170 days

8. Industry. The static storage period is that the evaporation can be completed in so many days at 22-24 ℃ and 1 standard atmospheric pressure under static state!

Tips for using yds-20 liquid nitrogen tank:

1. Before filling the liquid nitrogen tank with liquid nitrogen, first check whether the shell is sunken and whether the vacuum exhaust port is in good condition; at the same time, before filling liquid nitrogen, there should be a small amount of liquid nitrogen in the tank to maintain the precooling state.

2. When the liquid nitrogen tank is filled with liquid nitrogen for the first time, if a large amount of condensate water or frosting and other abnormal phenomena appear on the surface of the container for a long time, our store is responsible for replacing the new products free of charge (Note: when the container is just filled with liquid nitrogen, the surface of the neck cover appears in a short time; a small amount of frosting is a normal phenomenon, so don't worry). When there is no water drop or frost on the tank body, you can touch the shell by hand. If the upper part is cold and the lower part is hot, it also shows that there is a certain problem with the quality of the tank, that is, the daily increase and loss of liquid nitrogen is relatively large. It should be observed to prevent the loss of liquid nitrogen, and it is better to stop using it.

3. When it is used for long-term storage, it is necessary to replenish liquid nitrogen regularly. Generally, the residual liquid nitrogen should be one third of the total capacity.

4. When putting in or taking out the frozen articles, the opening time of the tank mouth should be kept as short as possible to reduce the consumption of liquid nitrogen, and the lifting cylinder should not be completely lifted out.
