High-Performance Automation with the Walchem Water Treatment Controller
The Walchem WPHPW100PNE pH Controller helps maintain accurate water chemistry in commercial and industrial systems. It continuously monitors pH levels and controls chemical dosing automatically. As a result, it helps prevent corrosion, scale buildup, and biological fouling while reducing manual testing.
The controller features a large backlit graphic LCD with simple icon-based programming. In addition, its intuitive menus make calibration, setup, and daily operation fast and easy. The multi-language interface also supports installations in facilities around the world.
The Walchem pH controller with probe includes a high-accuracy pH probe and probe tee assembly for continuous inline monitoring. The controller measures pH in real time and activates chemical feed pumps whenever readings move outside the programmed setpoints. Consequently, it maintains stable water chemistry with precise chemical dosing.
Unlike basic controllers, the Walchem water treatment controller includes three programmable control relays. These relays manage chemical feed pumps, bleed cycles, flow-based dosing, and biocide programs. Therefore, operators can automate multiple water treatment functions from a single controller.
The WPHPW100PNE comes in a rugged NEMA 4X / IP65 enclosure that protects the electronics in harsh environments. Furthermore, the universal 100–240 VAC power supply and optional 4–20 mA output simplify installation and system integration.
Available from Water Treatment Supply, the Walchem WPHPW100PNE pH Controller delivers reliable monitoring, automatic chemical control, and long-term performance for cooling towers, boilers, wastewater systems, industrial process water, and commercial water treatment applications.
Technical Parameters of the Walchem WPHPW100PNE System
Review the physical, electrical, and control architecture configurations of this multi-relay Walchem pH monitoring controller:
Control Logic & System Features
- Universal Dosing Profiles: Feed proportional to bleed time, makeup water volume, or elapsed percentages
- Integrated Biocide Timers: Configurable cycle triggers featuring pre-bleed and post-feed bleed lockout options
- Conductivity Bleed Logic: Intermittent sampling, boiler blowdown control, or continuous line bleed operations
- Data Loop Interfacing: Connects to building energy management systems (EMS) via an isolated 4-20 mA circuit
Use Cases & Industry Applications:
- Cooling Tower Water Conditioning: Automatically injects acid or scale inhibitors based on real-time pH readings to protect expensive heat exchangers.
- Industrial Wastewater Neutralisation: Regulates effluent discharge lines by neutralising acidic or alkaline process waste before environmental discharge.
- Commercial Pool & Aquatics Safety: Monitors pool sanitation chemistry, preventing chlorine dissipation by keeping pH levels steady.
- Boiler System Management: Automates periodic blowdown and raw water chemical pre-treatment cycles to prevent scale buildup along boiler tubes.

FAQs
- What components come standard with the Walchem WPHPW100PNE package?
This complete package features the industrial microprocessing controller unit, a high-quality real-time pH probe, and the necessary matching inline installation tee assembly. - Is the enclosure on this industrial pH controller safe for wet or outdoor environments?
Yes. The controller is housed in a rugged polycarbonate enclosure with a certified NEMA 4X and IP65 protection rating, making it dustproof, waterproof, and highly resistant to aggressive chemical fumes. - What types of flow meters can connect to this Walchem pH monitoring controller?
The unit features two dedicated digital inputs that support both low-speed dry contacts (0-10Hz contacting flow meters) and high-speed inputs (0-500Hz paddlewheel flow meters) for flow-proportional chemical dosing. - Can this Walchem water treatment controller connect to our central building automation network?
Yes. The controller features an optional, internally powered 4-20 mA analog output, allowing you to feed real-time water quality data directly to data loggers, recorders, or central building energy management systems. - How many dosing pumps or valves can this pH controller with probe assembly run at once?
The system includes three fully programmable, line-voltage powered mechanical relays (fused up to a total group current of 6 Amps). This multi-relay design allows it to act as a comprehensive Cooling Tower Chemical Controller, managing up to three separate chemical feed pumps or bleed solenoid valves simultaneously.
