The self-pressurizing liquid nitrogen tank is an efficient and safe liquid nitrogen storage equipment, which is widely used in life sciences, medical research and other fields. So what exactly is it?
First, we need to understand how a self-pressurizing liquid nitrogen tank works. It vaporizes a small amount of liquid nitrogen in the tank, causing the internal pressure of the entire container to increase. When the pressure inside the container reaches the critical pressure, the drain valve is opened to realize the continuous drain function. It is specially used to replenish liquid nitrogen in laboratory cryogenic containers to ensure the smooth progress of experiments.
Secondly, the safety of self-pressurizing liquid nitrogen tanks is also very high. It is equipped with double safety automatic control valves, which have double safety measures and are safer to use. It ensures that the liquid nitrogen tank pressure does not exceed the limit, thereby avoiding the risk of explosion.
