- Bart is preparing Spec document for vessel with vacuum insulation.
- An important unknown is to determine if a heat hexchanger can fit inbetween vessel and vaccum shell. Does it change something for the vessel manufacturer, and is it easier for them to use a coil instead ?
- What happens if the heat exchanger fails or leaks with time (shell to be oppened, expensive operation)...
- Sara, focuses on the design of the piping below the vessel.
