REHAU RAUTITAN Plumbing System
Product Information
The RAUTITAN drinking water installation is a compression sleeve jointing
technology designed to provide a hygienic and safe solution for water
circulation. It has undergone expert assessment to test its potential for
bacterial growth and ensure cavity-free spaces.
The assessment involved the development of a hygiene test facility and testing
the potential bacterial growth on the RAUTITAN compression sleeve jointing
technology. The test period started on 23 April 2015 and finished on 4 August
2015.
The results of the assessment showed that all joints demonstrated sterility
compared to germs in the water circulation. This indicates that the RAUTITAN
drinking water installation effectively prevents bacterial growth.

Reliable cavity-free connection – hygiene without compromise
Scope
Development of a hygiene test facility and testing the potential bacterial growth on the RAUTITAN compression sleeve jointing technology
Hygiene test facility
The hygiene test rig consisted of four test lines with 16 test pieces using the REHAU RAUTITAN system and was installed as a circulating ring with a thermostatically controlled constant temperature of 30 °C. The test rig was designed as a closed loop, operating at a constant pressure and generating a constant flow of 100 l/h with a maximum velocity of 1 m/s over the total test period of 104 days. The tests took place at the test lab of Fraunhofer UMSICHT. EVIAN mineral water was used as the test medium. All system components were DVGW certified.
Testing institute
Fraunhofer-Institut Environmental, Safety and Energy Technology UMSICHT – Oberhausen
Test period
Test start date: 23 April 2015, test finish date: 4 August 2015
Analysis
The scientific assessment was performed by taking micro-biological samples on all accessible connections according to recognized analytical protocols. The determination of total cell count of the water samples was determined by carrying out three decimal dilutions with buffer solution. From the original and the diluted samples, 0.1 ml was taken from each and transferred onto its own culture medium. Each culture medium was incubated at 30 °C . The colonies were counted after 72 hours (CFU per millilitre).
Cavity-free spaces with 0 CFU/cm2
Result
Overall, all joints showed sterility compared to germs in the water
circulation.
Conclusion – Fraunhofer UMSICHT
The tested RAUTITAN fittings showed a high tightness, which effectively
prevents bacterial contamination. According to the previous bacterial tests,
such as those listed above, the REHAU compression sleeve joint can be
described as a cavity-free joint.
