The ice crystal inside the liquid nitrogen container is mainly formed by the heat exchange between the inner and outer bladders of the container and the condensation of water and gas in the air. It is normal for the ordinary liquid nitrogen container to be slightly frosted. If the frost is serious, Be careful.
Under normal circumstances, the normal use range of liquid nitrogen tanks (XL-45 to XL-65) is 9.2 meters per hour and 8 liters per minute. If this range of use is exceeded, severe frosting will occur. When the gas temperature is low, it is important to note that it will have some damage to the equipment used. This phenomenon is also reflected in the serious frost on the bottom of the tank.
