Walchem Intuition-9 Water Treatment Controller

The Walchem Intuition-9 is a high-capacity, wall-mount water-treatment controller designed for the most demanding multi-loop chemistry installations — cooling towers, boilers, and industrial water systems where capacity, communications, and corrosion monitoring all matter. Four I/O slots scale to support multiple sensors, analog outputs, and Linear Polarization Resistance (LPR) corrosion measurement, and the relay rack expands from three to twelve outputs to drive metering pumps, valves, and sequencing loops.

WiFi or Ethernet brings remote access via the internet, LAN, BACnet, or Modbus/TCP, while a large full-color touchscreen with icon-based programming keeps setup simple in any language. Email reporting, datalogging, and on-screen + web-based graphing complete an enterprise-grade monitoring stack.
