Icebank
IceBank. - Model C -. Energy Storage. Tank. IceBank model C tanks are second generation thermal energy storage. They come in different sizes to accommodate differing space constraints and offer a significant benefit— tanks can be bolted to each other due to their modular, internalized main headers. That means less distribution piping is needed.

Experimental study on the thermal performance of a novel physically separated chilled water storage tank …
During charging, valve 1, valve 2, and valve 5 were opened, and the other valves were closed. Water was then extracted by pump 1 from the right of the tank through the bottom outlet pipe. After that, water was passed through a chiller, and then the cold water returned to the left of the tank via the diffuser.
