As the demand on water resources increases across the globe, improving the efficiency of cooling water treatment programs has emerged as a critical priority. Onsite management of the cooling system remains the best way to reduce water consumption, but this requires an adaptable portfolio of chemicals, as well as highly integrated monitoring and control technologies to surveil the system and dispense the right chemistry at the right moment.
Solenis’ proprietary OnGuard CW control system provides a holistic, performance-based approach to monitoring and controlling cooling water treatment programs. This control system combines advanced monitoring technologies and proprietary control algorithms with the most comprehensive family of chemistries to effectively manage any water treatment issue — corrosion, scale and biofilm — confronted by industrial operations. Plus, the control system is backed by a team of field professionals and applications engineers who are familiar with the local needs of their customers and can offer highly customized recommendations.
The OnGuard CW control system offers the following benefits:
- Improved control of corrosion, scale and biofilm
- Reduced downtime, improving operational efficiency
- Decreased water, energy and chemical use, reducing operational costs
- Prolonged asset life
- Reduced operator involvement
Key Technologies
Solenis’ OnGuard portfolio includes innovative sensors and analyzers that provide 24/7 monitoring and control of water treatment programs based on actual system performance data. When used individually, these technologies can deliver powerful results. When they are combined, their impact can be multiplied.
The OnGuard CW control system takes advantage of this effect by bringing together three technologies — the OnGuard 3B analyzer, the OnGuard 3H analyzer, and the OnGuard i controller — into a single consolidated unit, making it possible to efficiently manage the performance of the entire cooling water system. Using the control system, you will have unprecedented abilities to detect and monitor corrosion, scale and biofilm and then control the release of Solenis’ proven chemical solutions to stop system upsets in real time before they become larger problems.
Additional sensors and technologies can be included to monitor other important parameters. For example, introducing the OnGuard Tracker adds an extra dimension of control over chemical levels, enabling even greater precision.
Advanced Automation
At the heart of the OnGuard CW control system is a chemical feed controller with advanced automation features. The controller utilizes numerous input tags and multiple configurable functions to provide customized chemical feed and control for virtually any cooling water treatment application. The controller has the capability to verify chemical feed rates via the use of magnetic flowmeters and supports automated chemical drawdown assemblies (CDA) for chemical feed verification.
Industry-leading algorithms control the entire system. Choose either pre-programmed chemical feed algorithms for basic control or advanced performance-based algorithms for more sophisticated control. Either way, you’ll achieve more efficient management of chemical use and costs as the system anticipates corrective actions based on learned history and proactively addresses emerging issues.
Digital Solutions
The OnGuard CW control system can transfer data to and from customer distributed control systems. Additionally, it can share data with the Solenis™ Cloud to allow for 24/7 access to real-time data. Technical performance dashboards aggregate all technical data so it can be analyzed and monitored to ensure performance goals are met. The dashboards display performance scores of critical systems to provide at-a-glance visual indicators for rapid decision-making.
