control and dosage of feed water and steam boiler


FWS-Control provides full control of important parameters of the entire feed water and steam boiler system. The user-friendly handling leads to more efficiency, safe operation of the system and savings in energy and costs.

at a glance

  • measurement of pH, conductivity and residual oxygen content
  • optical oxygen measurement
  • analysis of thickening factor, dosing and closing times for vapour valve, ...
  • demand-oriented dosing of conditioning agents by continuous measurement
  • monitoring the threshold values of the feed water
  • optimized, continuous control of alkalization and residual oxygen binding
  • visualization of measured values and process data via display
  • alarm triggered by detected errors by automatic function control
  • data storage in the electronic operating diary or USB stick
  • optionally, networking with higher-level control centers and remote maintenance is possible

ideal solution for

  • food industry
  • refrigeration and air conditioning
  • metallurgy


  • deposits
  • layer formation
  • consequential damages by corrosion


  • saving potential of up to 8% of the operating costs of a steam boiler system
  • efficiency measure in the context of the energy management system according to ISO 50001
  • quality-related use of chemicals results in higher thickening, resulting in a reduction in energy losses and quantities of blowdown
  • current evidence: up to 71 % savings in exhaust vapour losts
  • current evidence: up to 50% savings in used chemicals
