Side View

We are still working on this area. Soon we will have all of these components labeled. Until then, here is a typical vertical tank, which has been cut-out to reveal the inside magic!

Side-view of a typical tank

This tank is equipped with two heat transfer devices. Both of them are  filled with a fluid, which is circulated (pumperd) through a heater or chiller to bring the fluid into the tank to a desired temperature.

The copper looking structure is the helical coil. The spacing of the pipe has been exaggerated to show the insides of the tank. Usually this spacing is about 1 to 2 pipe diameters.

The heat transfer jacket is like an outer tank surrounding the inner tank. The heat transfer fluid flows between the two tanks.

This tank is equipped with 4 straight standard baffles, 3 of which are visible in this cut-out view. They are attached to the tank wall and the baffles are spaced away from the wall.

The central silver colored rod is the shaft. This can be solid or hollow (pipe shaft). When the design calls for a large diameter shaft, pipes are often used to reduce cost, weight and to add strength. Shafts don't float in a tank. The upper flange is attached to the outboard shaft of the gearbox, which is not shown.

The blue structure is called an intermediary steady bearing. It surrounds the shaft with bearings. Sometimes this could be just a ring which is called a limit ring. Both of these devices protect the internals of a tank in the case that the fluid forces would otherwise bend the shaft. Many tanks have a steady bearing or a limit ring near the bottom of the tank. Instead of being suspended from the walls, they rest on top of a tripod, which is attached to the bottom of the tank.

This tank is equipped with 3 silver colored impellers. This particular example shows them to be low solidity hydrofoils (our example is of the LIGHTNIN A310)

We also see a drain hole in the bottom of this tank.
