KHS Hygiene Flush Box

Stagnation prevention has never been so economical

Stagnant areas in drinking water installations can pose serious risks to drinking water hygiene. They occur when the intended maximum use does not occur regularly. KHS Hygiene Flush Boxes help to restore the scheduled intended use through automated “forced withdrawals”. Water exchanges can be carried out in a controlled manner using the time, temperature and volume parameters. The KHS Hygiene Flush Boxes take into account the varying functional requirements of different building types. Three versions offer an economically optimal solution in each case:

• PURE for time-controlled interval flushing operation in small buildings (e.g. nurseries)
• PRO for large buildings with special hygiene strategies (e.g. hospitals)
• LITE for buildings with special cybersecurity requirements (e.g. military buildings)

A special design feature is the all-in-one concept: the variable installation housing enables either flush-mounted or surface-mounted installation. Thanks to their ultra-quiet water exchanges, the KHS Hygiene Flush Boxes are also perfect for buildings where comfort is important. Fast commissioning and permanent independent function checks are further highlights from the extensive feature list.

Maintaining drinking water hygiene in a resource-saving and sustainable way - by actively maintaining the temperature of cold water

Rising outside temperatures make it difficult to maintain the temperature
in cold water
In Germany, too, drinking water is only available to a limited extent in some regions during the summer months. This trend is being exacerbated by climate change, making it even more difficult to maintain drinking water hygiene. In order to realise a cold water temperature < 25 °C, the rising temperatures in buildings are generally countered with an increased frequency of temperature-controlled flushing measures. If the problem of a parallel rise in the building entrance temperature is added to this, the effectiveness of the flushing measures decreases even further - the water consumption increases drastically. Ergo: Maintaining hygienically uncritical cold water temperatures is only possible, if at all, with an immense consumption of the valuable resource of drinking water, and this with decreasing availability.

The solution: Active temperature maintenance with KHS CoolFlow
KEMPER KHS CoolFlow makes flushing measures for pure temperature maintenance in cold water installations redundant thanks to active temperature maintenance. A cooler and special thermostatic balancing valves are used in a cold water circulation system. This enables the system to guarantee permanent temperature maintenance < 20 °C. Combined with the flow splitter technology of the KEMPER KHS hygiene system, the circulation even works right up to the tapping points! KHS CoolFlow effectively saves drinking water, scores points with its low energy consumption and therefore usually pays for itself in less than two years.

Future-proof central hot water heating with connectable KTS water heaters PRO

With the connectable KTS water heaters PRO, our KTS ThermoSystem becomes a future-orientated, digitalised hot water heating system. Thanks to consistent further development, the system, which works on the flow principle, enables energy savings of up to 10 % with up to 200 % more output. KTS makes the provision of hot drinking water faster, more efficient, more hygienic, more innovative and smarter in almost all types of building and utilisation.

High demands on drinking water heating systems

With the increasing focus on harmonising the use of regenerative energy sources, maintaining drinking water hygiene and digital control and optimisation functions, there are new and demanding requirements for drinking water heating systems. As a consequence, building technology components need to be better-performing and more flexible than ever. This also applies to their ability to communicate with a central building management system and mobile devices. All the while, time is increasingly of the essence in planning and execution. This means future systems need to be highly favourable in terms of sizing, assembly and commissioning.

Drinking water heating with KTS water heaters PRO: faster, more efficient, more hygienic, more innovative and smarter

With numerous innovative product features, the KTS PRO fresh water stations offer an enormous range of services:

• Exceptional extraction range from 1.6 l/min to a maximum of 960 l/min
• Reduction of the flow temperature down to 62 °C - this can save up to 10 % energy
• Safe drinking water hygiene: consistent separation of the cold and hot areas within the fresh water stations as well as cascade rotation to prevent hygiene-critical stagnation areas in cascaded systems
• Up to 50 % faster installation time thanks to integrated accessory components that eliminate the need for additional installation and cabling work
• ‘Do-it-yourself commissioning’ in under 60 seconds with intelligent assistant
• Patented chimney system for efficient utilisation of the pump's service life
• Integrated data logger
• Access to digital services as part of the PRO functionalities of smart KEMPER products

Ensuring sustainable drinking water hygiene

The course for sustainable and efficient assurance of drinking water hygiene is already set when selecting the type of installation. Without additional auxiliary energy and flushing measures, ring installations with KHS Venturi flow-splitters, for example, enable up to 100 water exchanges daily in potential stagnation areas. Natural taps lead to the exchange of drinking water in all upstream wet cells. And Flow-Splitter installations do not only ensure drinking water hygiene in terms of stagnation prevention: the regular inflow of fresh drinking water achieves comparatively up to 5K lower temperatures in the bathroom installation. Temperature maintenance < 25 °C can thus be realised much more efficiently.

In combination with other system components such as KHS hygiene flushing or KHS CoolFlow, water exchange and temperature maintenance can be automated even in phases of operational interruption - sustainably, economically and in a resource-saving manner.

FROSTI® - The new level of sophisticated technology

Innovation hand in hand with the skilled trades
KEMPER has equipped its tried-and-tested, sophisticated frost-proof outdoor tap FROSTI® with new, useful features that enable the plumbing professional to save time and simplify installation and offer the end customer added operating safety and performance. The new development is the result of intensive discussions with experienced plumbers about adverse installation situations, critical end users, improper handling and unwanted access by third parties. Numerous problem-solving ideas and the new product features were developed on the basis of the knowledge gained.

New functions, new installation benefits, proven gunmetal
The top highlight of FROSTI® is the new operating handle with integrated overwind protection, which prevents damage to the fitting due to excessive closing torque: a gain in safety and convenience that satisfies end customers and minimises the risk of complaints! Thanks to the revised design, the valve blends into the wall environment in a visually appealing way. The operating handle, socket key handle and lockable handle are characterised by a uniform, harmonious design language.

In terms of ease of installation, the valve scores highly with the flexible collar, which also compensates for the angle of the sloping hole and ensures a clean, flush finish. This effect gives the valve additional support. The façade is not damaged when the outlet housing is tightened, preventing the thermal insulation from being pressed in. The newly designed mounting surfaces on the valve body offer the plumber the greatest possible support for optimum installation and enable installation without damaging the surface. The fitting also has an optimised anti-twist protection that locks securely into the fitting and thus protects the connection to the drinking water pipe from radial and axial forces during installation.

The corrosion-resistant, durable gunmetal material supports functional reliability and the maintenance of drinking water hygiene.

End users benefit from the unsurpassed new discharge rate of up to 45 l/min at 1 bar in DN 20 (40 l/min in DN 15).

The right valve for every application
FROSTI® is available as a kit version for installation during the shell construction phase (XL version for installation depths of up to 530 mm) and as a pre-assembled version for installation with the façade already completed.
