Thermal disinfection

Thermal disinfection of drinking water systems for proection against Legionella contamination

Thermal disinfection with hot water at 70° C is required after a positive test result for Legionella, which exceeds the technical intervention value in drinking-water pipe systems in compliance with the DVGW Worksheet Ordinance (TrinkwV) of 05.12.2012. Since installed stationary drinking water heaters are not designed for this output, a mobile heating centre is a sound solution in this case.

Quick and flexible use
For thermal disinfection, the entire drinking water installation including all tapping points must be flushed with hot water at 70° C for at least 3 minutes. The drinking water heated for this purpose should ideally come from a mobile heating centre. Such a mobile heating centre quarantees the required minimum temperature and can be used flexibly anywhere. Reliability and promt reaction are even more important, especially in case of an emergency, for example, in case of a positive result  for Legionella.

Hence our systems are designed for this purpose as well and can continously generate domestic hot water temperatures of up to 85° C.
