water analysis for industrial processes

our products are used in a variety of applications and industries:

monitoring of water softeners and reverse osmosis

OFS-Geräte bieten eine hohe Betriebs- und Prozesssicherheit durch eine vollautomatische Überwachung von Umkehrosmosen.

High operating and process reliability thanks to fully automatic operation - downstreamed systems such as steam boilers or reverse osmoses continuously receive softened water. The OFS devices guarantee this safety through the automatic operation and immediate signaling of threshold value exceedings and brine-shears, such as Softcontrol Data. Occasional hardness dips are therefore over.

quality-controlled regeneration triggering

Durch eine qualitätsgesteuerte Regeneration mithilfe von OFS-Produkten werden die Probleme gelöst, die sich durch zeit- oder mengengesteuerte Regeneration ergeben.

The regeneration of water softeners in industrial plants is usually time or quantity controlled. The resulting problems are resolved with a quality-controlled regeneration. This results in several advantages.

hot water and steam boiler systems

OFS-Produkte können Einsparpotentiale an Dampf- und Heisswasserkesseln erschließen.

For a smooth boiler operation, a good quality of the feed water is indispensable. In addition to protection against corrosion and deposits, uninterrupted saving potential are also available in the boiler house with continuous monitoring and appropriate control of the most important control parameters. OFS devices can exploit these saving potentials and thus contribute to the ecological handling of resources.
