$1,519.38
The Walchem WCT6A00PANNNPANNN Cooling Tower Controller is an advanced water treatment controller designed to automate conductivity monitoring, chemical feed, and blowdown control in cooling tower systems. Built on the powerful Intuition-6 platform, it combines real-time conductivity measurement, automated bleed and feed control, and dual biocide timer functionality to improve water quality and system efficiency.
Supplied as a complete pre-wired panel, this controller includes a graphite contacting conductivity probe and an inline flow switch manifold for safe, reliable operation. The integrated flow switch prevents chemical feed unless water is circulating, helping protect equipment while maximizing chemical efficiency.
The Walchem WCT6A00PANNNPANNN features a large color touchscreen with intuitive icon-based programming, built-in data logging, and six programmable control relays. It is an excellent solution for cooling towers, HVAC systems, commercial buildings, industrial facilities, and process cooling applications that require accurate conductivity control and automated chemical dosing.

Complete Cooling Tower Management with the Walchem WCT6A00PANNNPANNN
The Walchem WCT6A00PANNNPANNN Controller automates cooling tower water treatment. It helps control scaling, corrosion, and biological growth. As a result, it improves heat transfer, reduces chemical waste, and lowers operating costs.
The Walchem Intuition 6 Conductivity Controller features a large color touchscreen with easy, icon-based menus. Operators can adjust setpoints, view live system data, and review trend graphs in seconds. In addition, the multilingual interface simplifies setup for any facility. Built-in USB data logging also makes it easy to save and export performance records.
The controller continuously monitors water conductivity through the included graphite conductivity probe. When conductivity reaches the programmed limit, the controller activates the blowdown valve. Consequently, it removes high-TDS water and helps maintain proper water chemistry. The Walchem Bleed and Feed Controller can also operate chemical feed pumps based on bleed cycles or makeup water flow.
For added protection, the panel includes an inline flow switch manifold. The flow switch stops chemical feed whenever water circulation stops. Therefore, it protects equipment and prevents unnecessary chemical use. In addition, the dual biocide timer supports alternating or sequential biocide programs with customizable pre-bleed and post-feed lockout cycles.
The factory pre-wired panel reduces installation time and eliminates complex field wiring. Furthermore, the WCT Intuition 6 Controller provides six programmable control relays for flexible system control. It works well in cooling towers, HVAC systems, industrial process cooling, and commercial water treatment applications.
Available from Water Treatment Supply, the Walchem WCT6A00PANNNPANNN Controller delivers reliable conductivity control, automated chemical dosing, and long-term cooling tower protection.

FAQs
- What components come pre-assembled on the Walchem WCT6A00PANNNPANNN controller panel?
This turn-key panel package includes the WCT600 Intuition 6 controller head, a high-accuracy graphite contacting conductivity probe, a clear acrylic flow switch manifold with safety interlock, USA power cords, and pre-wired output pigtails mounted on a rugged backboard. - How does the Walchem dual biocide timer controller function on this unit?
The controller includes dedicated dual biocide timing programs that allow you to set up alternating or sequential biocide dosing schedules. It includes programmable pre-bleed functions to drop conductivity before dosing and post-feed lockouts to prevent bleeding off expensive chemicals prematurely. - Why is an inline flow switch critical on this cooling tower conductivity controller with probe?
The inline flow switch senses active water movement across the manifold. If circulation pumps trip or flow stops, the controller automatically locks out chemical feed outputs, preventing chemical pocketing inside stagnant lines. - Can I upgrade this WCT Intuition 6 conductivity controller to include Ethernet or 4-20 mA outputs?
Yes. While this standard model (PANNNPANNN code) comes without factory-installed analog outputs or Ethernet cards, the universal internal expansion slots allow field installation of optional Walchem communication and analog input/output boards. - What is the typical lead time for shipping this Walchem Intuition 6 conductivity controller?
This specialized panel-mounted controller package carries an estimated factory lead time of 2 to 3 weeks from order confirmation.
