Achieving consequent sanitary room hygiene is very challenging irrespective of the sanitary room being in a hospital, residential nursing home or school or similar objects. This is due to either the sanitary system not being used continually or because the risk of transfer of germs should be avoided as best possible.
A challenging task, that SCHELL has been committed to for many years. It is not surprising that we are globally regarded as one of the pioneers of technical solutions, who predominantly have one objective: to protect the health of the user.
Thus, e.g., many SCHELL fittings can be controlled without contact. On the one hand that improves the hygiene in heavily used sanitary rooms and, on the other hand, also saves water. But that is not sufficient. In objects where longer periods of interruption in use occur, e.g. schools, additional selectable stagnation flushing for electronically-controlled washbasin fittings also further contribute to hygiene. Then, at the latest 24 hours after using the last time, the fittings trigger a flow of water for approximately 20 seconds to prevent water stagnating in the pipelines and, thus prevent germs developing.
Also if it concerns preventing legionella, SCHELL provides a suitable solution. Thus, legionella flushing is integrated in nearly all electronically-controlled washbasin and shower fittings. It provides 5 minutes of continuous flow of hot water at 70 °C for thermal disinfection and, thus, removal of the dangerous pathogenic organism. And this is carried out reliably and completely without adding any chemicals to the water. Of course these fittings fulfil the requirements in accordance with worksheet W551 of the DVGW (German Technical and Scientific Association for Gas and Water).
And because it concerns water as a comestible, SCHELL naturally only uses materials suitable for water for their products, from which there is no change in the characteristics of the drinking water. Thus, our quality fittings meet all the requirements specified in TrinkwV 2000 (drinking water ordinance), DIN 50930 Part 6, DIN EN 1717 and KTW (recommendations for plastics that come into contact with drinking water)
