KS-201 Cooling Water Control

The KS-201 optimises the water supply in cooling water circulation systems. With connected level contacts, its control system provides the regulation of the water level and controls reliably the required feeding of water. The KS-201 provides fully automatic regulation of cooling water concentration by measuring the electrical conductivity and controlling the bleeding off. It captures the feeding and bleeding off volumes. Hardness stabilizers, corrosion protection, and pH regulators can be added in proportion to the given volume. Biocide dosing can be controlled by weekday and time of day or by time interval. For the conductance measurement we recommend the usage of our LWS-1 Conductance Probe.
