Automatically trigger regeneration of the softener

Softcontrol RM

The economy of a water softener can be improved by control and optimized activation.
Thus, Softcontrol RM offers monitoring of the soft water for increased hardness concentrations as well as the external regeneration release of the softener for quality-controlled double water softening systems.

at a glance

  • monitoring of variable water hardness threshold values from 0.01 mmol/l to 0.18 mmol/l
  • quality-controlled regeneration release of two columns
  • continuous measurement as long as water flows
  • ecological operation because there is no use of indicators
  • self-monitoring of the device system
  • separate alarm for water hardness and service
  • measuring value output via display and via 4 to 20 mA current loop
  • manual control via display
  • data storage in electronic operations diary (flash drive)
  • easy installation and parameterization
  • networking to higher-level control centers via LAN interface with MODBUS/TCP

ideal solution for

  • district heating
  • municipal utilities
  • hospital


  • uneconomicalness
  • too much water consumption
  • too much use of chemicals


  • increase in soft water throughput compared to volume controlled operation    
  • high efficiency for regeneration
  • alarm system for double water softening systems with high safety requirements for soft water quality
