Stagnation prevention

Drinking water hygiene has never been so convenient

To ensure the flawless functioning of a building installation, the planner has to take the maximum usage situation into consideration. In practice however this maximum usage is not the usual situation. Stagnating sections and insufficient hygiene in both the cold drinking water (PWC) and hot drinking water (PWH) can be the consequence. Changes in the use of the building or people within the building could have a similar effect. During the lifetime of a building, the actual frequency of withdrawals and volumes deviates strongly from the originally planned values. On top of that, the intended use is no longer guaranteed here.

The new KHS Hygiene Flush Boxes help restore the intended use through controlled “forced withdrawal”. Water exchange is controlled during this through the time, temperature and volume parameters.

KHS hygiene system

The KEMPER Hygiene System, KHS, prevents stagnation and the resultant impairment of drinking water quality. It ensures that fresh, hygienically perfect water is always available at every tap, taking into consideration efficiency and sustainability concerns. It offers every stakeholder, from the planner to the operator, from the installer to the end consumer, maximum security and safety in their daily contact with drinking water.
