Nitrex: A simple solution

Frequently Asked Questions

We rent tanks that are 160L and 230L. We can fill smaller or larger tanks owned by clients (however, we do not fill tanks smaller than 10L).

  • Southern California from Ventura to the southern border, as far east as Indio.
  • The San Francisco Bay Area.

Every ten minutes, our facility gets the latest tank level reading from your tank(s) via WiFi. We can see when your tank is getting low, and we know your typical usage patterns, so we will come and refill your tank . . . before it runs out. 

And, for complete peace of mind—something that is incredibly rare in the liquid nitrogen industry—you can also see your tank levels on your smartphone, any time of the day or night

We will text you ahead of time so you know we’re coming to fill your tank(s) and again after we fill them. 

You will never again have to call your supplier in a panic, face another sleepless night wondering if your tank is low (or worse—empty!), apologize to your boss for an empty tank, or drive to work in the middle of the night to check your tank levels. 

This is why customers who come to us stay with us. We have built our entire business around stress-free delivery of liquid nitrogen. As one customer told us recently, “I never have to worry about my liquid nitrogen anymore.”
