Equalizing tanks provide the water cooling system with a reservoir to compensate for the natural shrinkage of the coolant, for example in the form of diffusion through the hoses, and to prevent air bubbles
in the circuit, which in turn could lead to increased operating noise of the pump.
In addition to these purely practical aspects, expansion tanks can also provide visual highlights. Acrylic tubes are particularly suitable for this purpose, as their transparent optics offer various modding possibilities (lighting, coloured liquids etc.). In addition, they can be placed flexibly and are offered in different sizes.
This is a model from Bitspower with two screwed-in POM covers. These are sealed with two rubber rings against the acrylic tube. This is comparably thick and therefore particularly stable. The upper lid of the normally vertically installed expansion tank has a single 1/4 inch thread.
Particularly interesting: On the inside, the inlet opens into three individual openings, which are aligned laterally. This provides a special eye-catcher when the upper connection is used as an inlet and the water flows in three individual jets against the acrylic body.
In contrast, the lower POM cover has three 1/4 inch threads. One of these openings is connected to an internal flow tube. This is used as an inflow if the inlet and outlet are both led from the underside to the expansion tank. If, on the other hand, the inflow is from the top, one of the other two openings should be used as the outflow, as otherwise air will be sucked in if the water level is below the height of the fault pipe.
Two plugs are included with the expansion tank, which seal the two openings that are not required. One of these plugs is designed to be transparent and can accommodate an optional lighting module, which can be used to create effective lighting mods.
The scope of delivery also includes two fastening rings. These are simply pushed over the tube and pressed together at the desired position. Thanks to the straight outside and corresponding holes, they can be flexibly screwed down. The screws required for installation and the necessary connections are not included in the scope of delivery.
