tubra®-nemux S/M

Fresh water station

A electronically controlled fresh water station with many options such as circulation programs, cascade function for up to 4 stations and hygiene programs. The nemux M has a more powerful plate heat exchanger.

  • complete stainless steel piping
  • optimized insulation according to GEG
  • variants with full stainless steel PHE available
  • comfort function (warm start)
  • floating set point function: at low buffer temperature, the set point is reduced and thus the buffer tank is not mixed
tubra®-nemux cascade piping

The tubra®-nemux cascade piping allows a space-saving installation of two tubra®-nemux fresh water stations one above the other on the wall. Together with the cascade ball valve set, the primary and secondary piping can thus be realized.
