Water Treatment Controllers — Walchem Intuition
Turn dosing and bleed/feed into a measured, documented process. Walchem Intuition controllers combine multi-parameter sensing, smart control logic, and web-enabled visibility so towers, boilers, RO/DI and closed loops run clean, efficient, and compliant.
- Multi-loop control for conductivity/TDS, pH/ORP, make-up, and oxidant feed with event/fault interlocks
- Browser-based remote access (no special software) plus alarm notifications and data logging
- Flexible I/O: sensor inputs, relay outputs for pumps/valves, and analog 4–20 mA signals (model-dependent)
- Panel-ready footprints, NEMA-rated enclosures, and easy menu-driven setup reduce startup time

Why Intuition Controllers Beat Timers & Manual Adjustments
How They Work
- Sensors measure conductivity/TDS, pH, ORP, temperature and more, feeding the controller’s logic.
- Relays and analog outputs command metering pumps, solenoid valves, bleed valves, and alarms.
- Onboard web server provides remote visibility, configuration, trending, and secure access.
Where They Win
- Cooling towers & boilers: stable cycles of concentration, optimized chemistry spend
- RO/DI & closed loops: protect membranes and metallurgy, document compliance
- Multi-loop sites: one interface, consistent logic, plant-wide alarm discipline
Best-Fit Intuition Configuration by Service
| Service | Ideal Configuration | Recommended Model | Why It Works |
|---|---|---|---|
| Cooling Tower Automation | Conductivity bleed, inhibitor feed, biocide timer/ORP; make-up & flow interlocks | Intuition 6 | Balances cycles, keeps fouling/corrosion in check, logs events and alarms |
| Boiler Blowdown & Chemical Feed | TDS control, phosphate/oxygen scavenger feed, low-level/lockout interlocks | Intuition 6 | Stabilizes TDS and chemistry to protect tubes and save fuel/water |
| Seawater / Cu–Ni Protection | Control strategy tailored for copper–nickel metallurgy; setpoints and alarms per spec | Intuition 6 Cu/Ni | Streamlines monitoring and dosing where Cu–Ni heat exchangers are used |
| RO/DI Skids & Pretreatment | pH/ORP, conductivity, antiscalant feed, pre/post alarms; data logging | Intuition 6 or 9 | Protects membranes and provides traceable performance data |
| Closed Loops / Glycol Systems | Corrosion control, biocide scheduling, make-up monitoring, temp compensation | Intuition 6 | Reduces under/overfeed risk and documents seasonal changes |
| Multi-System Plants | Multiple sensor inputs and outputs, segmented alarms, remote dashboards | Intuition 9 | Higher I/O density with centralized visibility and consistent logic |
Note: Exact I/O, protocols, and sensor options are model- and option-dependent. We’ll confirm your requirements before quoting.
Materials & Performance
Hardware & I/O
- Enclosure: wall-mount, NEMA/IP-rated housings suited for mechanical rooms or panel mounting

- Protocols such as Modbus TCP/IP and others available on select configurations
Accessories & Panel Options
- Sensors: conductivity, pH/ORP, temperature, flow/level, oxidant probes (free/total chlorine)
- Sample panels: flow-regulated cells, rotameters, strainers, isolation valves, drains
- Pump interlocks: level switches, drum-empty alarms, door/lockout inputs
- Bleed & make-up valves with proper Cv and fail positions; backflow prevention
- Networking: secured remote access, user roles, alarm recipients, time sync
Intuition Controllers vs. Common Alternatives
| Use Case | Intuition (6 / 9) | PLC + HMI | Analog Timers/Relays | SCADA Only |
|---|---|---|---|---|
| Water treatment loops | Purpose-built, faster startup | Custom engineering | Manual tuning | Needs field controller |
| Remote access & alarms | Built-in browser + alerts | Integration required | Not available | Depends on field data |
| Data logging / compliance | Native logging & export | Project-specific | None | Historian needed |
| Total installed cost | Low–Medium | Medium–High | Low (but manual labor) | High without field control |
What We Need to Configure Your Intuition (5-Minute Worksheet)
- Application: tower, boiler, RO/DI, closed loop, seawater/Cu–Ni, or other
- Sensors/specs: which parameters to measure, ranges, and mounting preferences
- Outputs: number of pumps/valves to control, interlocks, analog outputs required
- Networking: remote access, alarm recipients, protocol preferences
- Environment: enclosure rating, panel space, power, and any site standards

Controller FAQs
What’s the difference between Intuition 6 and Intuition 9?
Intuition 6 covers typical tower/boiler and single-system needs with a practical mix of inputs/outputs. Intuition 9 offers greater I/O density and flexibility for multi-system or higher-complexity sites. We’ll map your loops to the right model.
When should I choose the Intuition 6 Cu/Ni variant?
Use Intuition 6 Cu/Ni when your system design and metallurgy call for copper–nickel-focused control strategies and setpoints (e.g., seawater or coastal cooling applications). We’ll confirm sensor and setpoint requirements with your spec.
Do these controllers support remote access and alarms?
Yes. Intuition controllers provide browser-based access for configuration/trending and can send alarm notifications when configured. Protocol and logging options vary by model—tell us your IT standards and we’ll align the selection.
Can one controller run multiple pumps and valves?
Yes—via programmable relay outputs and, where equipped, analog outputs. We’ll assign outputs to your metering pumps, bleed valves, make-up valves, and interlocks with clear labels and documentation.
What do you need from me to quote the right controller?
Tell us the service (tower, boiler, RO/DI, closed loop), which parameters you want to measure/control, the number of pumps/valves, and your remote access needs. Photos of the existing panel help speed things up.
