Model 3175e Boiler and Cooling Tower Conductivity Controller Overview
Maintaining the correct conductivity in cooling towers and boilers is crucial for system efficiency, corrosion prevention, and chemical savings. The Model 3175e excels as a cooling tower conductivity controller and for boiler conductivity control. This water treatment programmable controller provides:
- Accurate and reliable control of boiler and cooling tower conductivity. A standard secondary input may be used to control ORP or pH.
- An intuitive and easy-to-program menu with the familiar 1575e menu interface. Configure for either cooling tower, boiler, or condensate applications with appropriate conductivity sensors.
- Larger 7” responsive touch screen display for quicker setup compared to using a keypad.
- Updated processor for modern connectivity and datalogging.
- Email alarm notifications.
- Reliable circuitry that has been proven for two decades to accurately control your water chemistry.
- User-selected relay options for a high level of application flexibility.
- Configure relays to your preference – for setpoint control, based on water meter, percent of blowdown or percent of time.
- Up to 12 scheduled feeds can be configured for excellent control of your system.
- Affordably priced between our Model 1575e and NexSys water treatment control systems.
