Advanced Cooling Tower and Boiler Controllers
An eController from Watertech of America can take your water treatment control program out of the dark ages. These controllers have the latest, most advanced, cooling and boiler water control methods available on the market. That, combined with 21st century remote monitoring capabilities make this the best controller available on the market today.
Over the years many different methods of controlling boiler and cooling water systems have emerged. Many of these have become industry standards and are found in all of the leading controllers. The eController includes all of these industry standard controls plus many new, innovative options that have the ability to improve system performance. Some of the more advance features include:
ORP-based Biocide Feed
Typically oxidizing biocides have been fed according to weekly or monthly timer. The disadvantage of this method is that it does not respond to changes in your system. The same amount is fed regardless of what the true demand is. The result can be that you may be overfeeding (leads to wasting product) or underfeeding (leads to poor system performance).
The eController has the ability to monitor the Oxygen Reduction Potential (ORP) of your system. The ORP of your system can be related to the biocide demand which will then control how much biocide is fed into the system. The controller logic allows you to enter an ORP setpoint which it then maintains. This ensures that you always have the proper amount of product in your system. In addition, alarms can be sent to your operators when the ORP exceeds a high or low set point.
Most methods of control assume that your chemical feed pumps are delivering the correct amount of product based on your system conditions. Now, with the newest version of the eController we can control you system based on the actual amount of product that is being delivered. It accomplish this we use an accurate, affordable flow meter that measure the actual amount of chemical that your pump is delivering. Measuring this volume allows us to enter the optimum feed rate into the eController. The eController then uses the volume of make up water to determine how much product needs to be feed. The chemcial feed pump is activated until that amount of product is fed. No other method of control provides this level of accuracy for feeding chemicals into a boiler, cooling tower or any other water system.
