The expansion tanks of the aqualis series are equipped with a tube made of borosilicate glass which, in contrast to the plexiglass often used for tube expansion tanks, has a very high hardness and scratch resistance, very low thermal expansion and excellent chemical and thermal resistance. The glass tube of the 100 ml and 150 ml variants has an outside diameter of 50 mm and a wall thickness of 5 mm. Base and lid of the aqualis series are made of Delrin, lid and base are connected by a stainless steel rod.

The aqualis D5 100/150 ml variants are designed for direct mounting of a Laing D5 pump on the expansion tank. On the rear side, four decoupling rubbers (not included) can be screwed into the base of the expansion tank for mounting on the PC housing.

All 100 ml and 150 ml variants are optionally available with a nano-coating that allows water to simply roll off the inside of the glass tube.

Please note: The expansion tank is supplied without connections, please order suitable connections separately. Laing D5 pump and decoupling rubbers are not included!
