Product Description

The softening unit of the Honeywell NK300S-SOFT facilitates the softening of heating water according to VDI-guideline 2035/I. Limescale and thereby caused damages and malfunction in hot water heating system (DIN EN 12828) are avoided efficiently.
The refilling combination fitted on the inlet and based on a BA-type backflow preventer protects the potable water supply against back flow of heating water according to EN1717.
  • Integrated water meter simplify the determination of cartridge exchange
  • Easy exchange of cartridge without tools
  • Constant connection with the drinking water supply in accor-dance with EN1717 by hose line or piping is possible
  • Optimal protection of the drinking water supply system
  • Backflow preventer approved for noise level protection, class 2
  • Pressure reducing valve approved for noise level protection, class 1
  • Pressure reducing valve with inlet pressure balancing - inlet pressure fluctuation does not influence the outlet pressure
  • Outlet pressure adjustable and directly at the pressure gauge readable
