Aquacomputer ULTITUBE 50 PRO Reservoir

The expansion tanks in the ULTITUBE series are equipped with a tube made of borosilicate glass, which, in contrast to the Plexiglas often used for tube expansion tanks, has a very high degree of hardness and scratch resistance, very low thermal expansion and excellent chemical and thermal resistance. The glass tube has an outer diameter of 65 mm and a wall thickness of 5 mm. Both ends of the glass tube are firmly connected to metal rings made of black anodized aluminum, which do not come into contact with the cooling medium. The base and lid of the ULTITUBE series are made of durable acetal and screwed to the glass tube. This means that a large opening is available for filling the expansion tank after unscrewing the lid.

A filter element made of a fine stainless steel wire mesh is integrated into the base of the tank, which not only functions as a particle filter but also separates air bubbles. The filter element is integrated into a rubber molded part and can be rinsed out under running water, for example. The seal in the upper area of the glass tube is also designed as a rubber molded part for easy installation and is therefore securely positioned when the lid is screwed on.

The PRO version of the ULTITUBE has a gas exchange membrane integrated directly into the lid of the expansion tank. The membrane continuously compensates for pressure fluctuations caused by temperature changes without coolant escaping.
An RGBpx-compatible LED ring with 13 individually addressable LEDs is included in the scope of delivery and can be used to effectively illuminate the expansion tank. An Aqua Computer control unit with RGBpx output is required to operate the LED ring (e.g. D5 NEXT, not included in the scope of delivery). At the end of the strip there is a connector for connecting another RGBpx component.
For additional fastening of the expansion tank in the upper area of the glass tube, a rubber fastening ring with a stainless steel insert is included in the scope of delivery.

Fastening material for mounting on a side/rear wall or for standing mounting is included in the scope of delivery.
