I order and use thousands of gallons of LN here at work all the time. The pressure containers that they are stored in have an active venting system. The LN evaporates ALL THE TIME, even when under pressure, and you HAVE to have a venting system otherwise the holding tank will explode violently. LN cannot be used in a closed loop for these reasons. After time, the LN will totally evaporate out of the venting system, even if I never take any liquid out.

The whole reason LN even works to cool anything down is because of the nature of this reaction.

Let me end this LN discussion, and hopefully any other LN questions for the rest of eternity with this statement:

"Forget about LN as an everyday coolant unless you have thousands of dollars and the time to spend on replenishing and refilling containers every couple of hours. LN is only useful for time limited experimentation."

I will not waste my time responding to any questions regarding the usage of LN at this point.
