The reservoirs of the ULTITUBE series are equipped with a tube made of borosilicate glass: which in contrast to the Plexiglas often used for tube reservoirs, has a very high 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 with metal rings made of black anodized aluminum that do not come into contact with the cooling medium. The base and lid of the ULTITUBE series are made of durable acetal and are screwed to the glass tube. After unscrewing the cap, there is a large opening for filling the expansion tank. A filter element made of fine stainless steel wire mesh is integrated into the bottom of the container, which, in addition to its function as a particle filter, also separates air bubbles. The filter element is integrated into a molded rubber part and can be rinsed out under running water, for example. The seal in the upper area of â € < â € < the glass tube is also designed as a molded rubber part for easy assembly and is therefore securely positioned when the lid is screwed on.
The PRO version of the ULTITUBE D5 has a gas exchange membrane integrated directly into the lid of the reservoir. Pressure fluctuations caused by temperature changes are continuously compensated for via the diaphragm without coolant being able to escape. An RGBpx-compatible LED ring with 13 individually addressable LEDs is included and can be used to effectively illuminate the reservoir. 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. A rubber mounting ring with a stainless steel insert is included in the scope of delivery for an additional, vibration-damping attachment of the expansion tank in the upper area of â
