The expansion tanks of 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 hardness and scratch resistance, a 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, which do not come into contact with the cooling medium; The base and lid of the ultitube series are made of resistant acetal and screwed to the glass tube;
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 in the bottom of the container and, in addition to functioning as a particle filter, also separates air bubbles; The filter element is integrated in a molded rubber part and can, for example, be rinsed out under running water; The seal in the upper area of 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;
An aqua computer d5 pwm pump is mounted directly on the bottom of the expansion tank; The performance of the pump can be set using a pwm signal, and a speedometer signal is also available to - MONITOR the pump function; The pump's electronically commutated ball motor runs extremely quietly and has a long service life; When developing the expansion tank, care was also taken to ensure optimum flow behavior, the result being extremely quiet and smooth operation of the pump;
Fastening material for mounting on a side / rear wall or a standing mounting are included in the scope of delivery; Four soft rubber decouplers are included for decoupling; Technical specifications: filling volume: approx; 470 ml connection thread: g1 / 4 operating voltage: 8;
24 v dc power consumption: 23 w at 12 v pressure at 12 v: 3.7 .
