Controllers are an essential part of any well-designed feed and control equipment package. Our experience in designing feed and control solutions has given us familiarity with a wide variety of manufacturers in the industry. We recognize that there are many good choices for controller manufacturers and that is why we offer many of the top brands. You can choose from controllers available in our on-hand inventory or allow us to custom order the controller of your choice.

We are a stocking provider of Walchem, ProMinent, Advantage, Pulsafeeder, and more. These controllers offer features such as Internet connectivity for superior control as well as electronic data management. We inventory these product lines so that we can offer you both a quick turnaround time and competitive pricing. Our team also has extensive experience custom designing PLCs for both off-the-shelf and unique applications.

The Need for Cooling Tower Chemical Controllers

Controllers keep feed and control systems running by receiving inputs from different process components, analyzing them and managing condition changes within a control loop. Ultimately, these mechanisms attempt to minimize the difference between the setpoint and the process variable of a system.

With controllers integrated into your feed and control equipment, you can:

  • Improve process safety: Water treatment controllers improve the steady-state accuracy of your system, improving the overall stability of your infrastructure. When dealing with chemical injection, precision is essential to create inhibition effects without making cooling water unsafe. A water controller will also ensure this accuracy for ongoing system safety and performance.
  • Increase efficiency in process guidance: Improving processes is a leading goal for many operations. Controllers are designed to automatically improve system activities based on the readings it receives, making it far easier to make process improvements. Using real-time data as guidance, allows you to operate your systems at peak efficiency for energy and water usage.
  • Save money: A water treatment controller can lead to savings in a couple of ways. Initially, it can lead to more efficient use of chemicals in metering processes, helping you extend chemical supplies and prevent overload of your metering systems. Boiler water controllers and cooling tower chemical controllers can also help you save on the effluent costs that come with metering chemical surpluses, as you’ll use chemicals more effectively.
  • Gain transparency: With a cooling tower chemical controller, you gain accurate data in real-time regarding system performance. This data is useful for guiding process improvements and decision-making in your organization. Modern technology supports accessibility and ease for navigating collected data and generating valuable insights.
