There are two methods of supplying liquid nitrogen storage tanks, one is to find a local gas company to fill them, and the other is to replenish them yourself!

Those looking for gas companies generally have volume requirements, and large volumes are replenished.

There are more ways to replenish yourself, either manually, with the help of a liquid nitrogen pump or a self-pressurizing liquid nitrogen tank.

If it’s a small liquid nitrogen storage tank, then go with the manual method!

Use foot pedal or mechanical liquid nitrogen pump if you want to save effort!

Because small liquid nitrogen storage tanks can carry less liquid nitrogen, such as 6 liters or 10 liters, they can be replenished manually with fewer steps and easier to operate than with tools, requiring only a funnel and a tank of liquid nitrogen.

Place the funnel at the mouth of the liquid nitrogen tank, a small tank can be replenished by one person lifting it, and a larger one can be lifted by two people working together.

There is no technical difficulty in aligning the funnel and pouring it in when filling, just do a good job of protection.

If you use a foot pedal or mechanical liquid nitrogen pump, align the pump’s infusion port with the mouth of the liquid nitrogen storage tank and output liquid nitrogen by foot pedal or with the help of electricity.

Small liquid nitrogen storage tanks supply liquid nitrogen in the above two ways, according to their own needs can choose.
