Trouble Shooting: Can't fill up cryo tank
You have a low pressure commercial linquid nitrogen tank.
When this happens, you don't hear very annoying loud noise. However, some
low pressure commercial tanks still work - just that it takes longer. On
the other hand, almost all those tanks have a pressure build-up valve, which
by default is closed. In this case, you should open it and see if you get
pressure back. If it does not work, call up the supplier and complain*.
------------------------------------------------------------------
* Normally you need liquid nitrogen tanks of 235 psi. |
