TECEflex - Hygiene box

So that cold water remains hygienically cool

TECE Hygienebox
The TECE Hygiene Box enables quick and easy thermal decoupling of the cold water.

When installing bathroom fittings the TECEflex Hygiene Box automatically meets the required standards for drinking water. The TECEflex Hygiene Box thermally decouples the hot water circulation line from the fitting connection, and therefore reliably prevents heat from being transferred via the fittings to the cold water side.

Made from prefabricated components, it prevents the cold water from being heated above the permissible 25 °C.

  • Drinking water regulations are automatically met - cold water stays cold.
  • Prefabricated components ensure efficient assembly and reliable, safe performance.
  • Insulation shells make it easier to connect the pipe insulation.
  • High compatibility with different pipe adapters.
  • Offers designers and contractors protection from cost-intensive complaints.

Using the Hygiene Box, cold water will remain cold

To develop the Hygiene Box, TECE looked at installation variants where the circulation lines run above the tap connection at a fixed distance. The warm water is supplied by a short stub line running vertically downwards.

This is designed to ensure stable stratification, resulting in thermal decoupling of the hot water pipe and the tap connection. Therefore heat transfer no longer occurs in the tap. In the past circulation lines often led all the way up to the tap to avoid stagnation in the stub lines. However, this led to an inadmissible heating of the fittings and the cold water side.

A long stub line will reduce heat exchange but bears the risk of stagnation.
The TECEflex Hygiene Box provides a simple and effective solution.

Thermally decoupled cold water side

The ready-to-connect Hygiene Box produced by TECE as a result of optimising the process, provides a practical solution to the problem. It guides the warm water pipe above the warm water wall disk. In this short, vertical connection piece between the wall disk and the circulation line, stable thermal stratification is created, resulting in thermal decoupling of the warm water pipe and the tap connection. This prevents unreliable heating of the cold water side, so the fitter won't get any complaints.

The insulated, ready-to-connect TECE Hygiene Box is available by itself for the warm water connection, as an assembly unit with a double wall disk for the cold water connection, and as a sanitary module for the TECEprofil dry-wall system.
