The ideal solution for all large plants

The issue of water hygiene is of particular relevance in the case of buildings with a large hot water demand. In hotels, hospitals, sports halls and homes for the elderly, the supply of hot water is extremely important. There are clear legal requirements pursuant to the German domestic water Ordinance (Trinkw.V 2000).

The ROTEX Sanicube hot water storage tank optimally meets the most demanding water hygiene requirements, since its operates like a flow water heater with regard to domestic water. Where there is a demand for large volumes of hot water, several ROTEX Sanicubes are simply connected to each other like modules. This has the advantage that the available space can be used in various ways. With the appropriate control technology equipment, it is also possible to install decentralised hot water storage tank systems in large supply networks.

Thanks to its light weight and its favourable dimensions, the Sanicube hot water storage tank is easy to transport and can be easily incorporated into existing buildings. In this case, large hot water storage tank systems can be connected to each other.

The variable storage tank system

The ROTEX Sanicube enables a very wide range of system variants. It is possible to meet the most complex demands with the different heat exchanger designs in the ROTEX Sanicube range. As a result, several heat sources can be integrated to produce additional heat extraction for a swimming pool or similar. In these cases, the whole systems usually remain relatively simple and clearly arranged and the control technology costs are generally low.

In the event of a subsequent change in the performance requirements, the system can often be modified very easily and flexibly without having to increase or decrease the number of Sanicubes owing to the modular layout.

Possible fields of application

The calculation of the required number of Sanicube storage tanks and the corresponding total heating output depends on the required maximum withdrawal quantity (withdrawal per unit of time) and on the withdrawal profile based on the dimensioning. Inside large widely dispersed buildings, it can also often be worthwhile to distribute several Sanicube storage tanks decentralised outside the building and to install them as close as possible to the consumers, thereby minimising heat losses and saving on pumps and expensive pipelines.

Hotels or hospitals often require large volumes of hot water instantly. The volume of heat stored in the ROTEX Sanicube is so large that a momentary increase in demand can be covered, even if the recharging output of the heat generator is comparatively small.

Short-term hot water output for each Sanicube unit therefore does not depend on the output of the heat generator to any great extent. If several Sanicube storage tanks are connected to each other in a large system, the outputs of the individual storage tanks are added to each other.
