Safety tubes

Safety tubes

For absolutely reliable media separation with best thermal contact

Safety tubes are used for economical and safe heat transfer. The double wall tubes feature defined leakage paths for the absolutely reliable separation of fluids. For your individual requirements concerning fluid dynamics, we decide on the most suitable surface structure. Our GEWA-safe tubes are a reliable and safe choice for applications such as the direct heating of drinking water using critical fluids as in heating technology or for controlling the temperature of sensitive chemical processes.
