Geberit Hygiene System We pull out all the stops

When it comes to creating an efficient concept for regular water replacement, Geberit offers a comprehensive solution that really does tick all the boxes.
The goal: customised solutions for maintaining the quality of drinking water in every drinking water installation, regardless of the frequency of use.

The Geberit Hygiene System includes suitable, hydraulically-optimised piping systems, practical piping components, hygiene flush units, sensors and intelligent tools for controlling and connecting sanitary appliances during operation.

Control electronics with interval flush mode

In some cases, simple solutions for automatic flushes are all that is required. The additional option of programming interval flushes is available in many Geberit washbasin taps, as well as urinal and WC flush controls.

Geberit HS01 hygiene flush unit

If pipes are no longer in use and drinking water is stagnating there, the Geberit HS01 hygiene flush unit can be used until the unused pipes are removed.

Safely prevent stagnation with a system

Stage 1: Correct piping

1. Optimum pipe installation

Description

  • Smallest possible pipe diameter
  • Looped pipe installation on the floor with a frequently used consumer at the end of the pipe
  • Thermally decoupled pipe layout on the floor
  • Separate boxes for hot drinking water (PWH, PWH-C) and cold drinking water (PWC)
  • Proper insulation of the pipelines (PWH, PWH-C, PWC)

Benefit:

  • Low pipe contents
  • Short draw-off times
  • Low risk of stagnation
  • Reduction of the thermal load on the cold-water pipe

Stage 2: Regular flushing

1. Optimum pipe installation
2. Automated water replacement by hygiene flush unit

Description: In addition to stage 1

  • Use of an automated flushing device to ensure water replacement when not in use

Benefit: in addition to stage 1

  • Flushing programmes as required (time or interval programme)
  • Ability to also flush hot water
  • Configuration, function test, recording and maintenance via the Control app
  • Planning flexibility afforded by different solutions for automated water replacement
  • Connection to building automation via Digital I/O

Stage 3: Controlled rinsing

1. Optimum pipe installation
2. Automated water replacement by hygiene flush unit
3. Targeted water replacement by means of analogue sensors

Description: In addition to stage 2

  • Takes into account the temperature profile and stagnation behaviour

Benefit: in addition to stages 1 and 2:

  • Temperature-controlled flushing programme
  • Water replacement ensured by means of volume measurement
  • Ability to record the flushed water volume

Stage 4: In the future: clever rinsing

1. Optimum pipe installation
2. Automated water replacement by hygiene flush unit
3. Targeted water replacement by means of analogue sensor technology
4. Optimised operation through networking

In the future, the connected Geberit Hygiene System will bundle all information flows and offer seamless integration into building automation.

Flush modes for any operation

Interval flush mode

In interval flush mode, a flush takes place at regular intervals if the drinking water installation is not in use or is only used to a limited extent. There is no fixed flush point in this operating mode. This makes it possible to comply with the requirements regarding regular water replacement in accordance with DIN EN 806-5 and VDI/DVGW 6023-1.

Time flush mode

The time-based flush starts at fixed times. It starts at a specified time of day (e.g. 6:00 p.m.), combined with one or more days of the week (e.g. Tuesday, Thursday and Sunday). When actuated, the flush lasts for a specified, adjustable flush time.

Temperature flush mode

Flushing the pipes in rooms where water temperatures reach the critical range due to the use of the room. In this operating mode, the flush starts when a particular temperature is reached (e.g. standard specification for PWC max. 25°C). The flush ends either when a stop temperature is reached or after a maximum predetermined flush time.

If the specified temperature is not exceeded within a predetermined time frame, the control actuates a routine flush. The routine flush is interval-based. The enable time can be used to set a time frame during which the hygiene flush unit should not actuate a flushing process (e.g. from 10:00 p.m. to 8:00 a.m. in hotels).
