[3dem] Help about ice condensation on LN2 tank mounted to Titan Krios

Hello 3DEMers


We put a 230L lN2 tank in Krios room to cool Autoloader and scope.

The valves of gas/liquid are always open to make sure auto-refilling work.

Unfortunately, because the temperate of the valves area is much colder than the room temperature, the water molecule in the room condenses onto the valve area, a dense ice growing on top.

This ice melts into water and flows to the ground when the tank is close to emptiness, which bugs me a lot since there are nearby pipes/pumps.

It's almost impossible to remove the tank immediately every time when the tank is almost empty, since the gauge is not that accurate to know the liquid level.

I'm wondering how your facility deal with this issue.

Any suggestion would be greatly appreciated.

Thanks.


Best regards,

Aguang at UT Austin
