Boiler Controllers

Specter’s Series 9000 is designed and manufactured to meet the highest quality standards. Each transducer’s output is digitally mapped to correct for any non-linearity or inaccuracies in the sensing element. This digital correction provides the most accurate and flexible pressure transducer in the industry.

Three powerful control outputs make the Walchem W100W a more versatile, high value choice among entry level water treatment controllers.
The W100W series provide an economical and reliable way to keep your water treatment program under control.

Key Features:

• Large display with icon based programming makes setup easy
• Universal sensor input provides extraordinary flexibility; the same controller can be used with almost any type of sensor needed
• Multiple language support allows simple setup no matter where your business takes you
• Three control outputs allow the controller to be used in more places than other entry level models

• Complete flexibility in the function of each relay
• On/Off Setpoint
• Time Proportional Control
• Pulse Proportional Control (when purchased with solid-state rel ays)
• In-range or Out-of-range activation
• Timer-based activation
• Activation based upon the state of a contact closure
• Timed activation triggered by a Water Contactor or Paddlewheel flow meter’s – accumulated total flow
• Activate with another output
• Alarm

Typical Applications:

• Wastewater neutralization & disinfection
• Food and Beverage disinfection
• Potable water treatment
• Swimming pools & spas
• Boiler water treatment control
• Cooling tower biocide control
• Metal finishing & printed circuit board
• Irrigation & fertigation
• RO Systems
• Condensate water treatment control

Walchem cooling tower controllers
The cooling tower control system shall be a capable of measuring system conductivity and temperature.

The conductivity sensors shall be either a contacting style or an electrodeless style. An optional second sensor shall be a choice of pH, ORP, PTSA, free chlorine, total chlorine, chlorine dioxide, ozone, Peracetic acid, or hydrogen peroxide.

Six digital inputs are available for sensors that shall include a flow switch, contacting water meter, paddlewheel flowmeter or other dry contact devices.

Outputs shall include six mechanical relays, and two optional 4-20 mA outputs.

Digital communications shall be via Ethernet. The controller shall be accessible via the Internet for configuring, data logging, and control of relay outputs.

The USB port shall provide the ability to upgrade the software in the controller to the latest version, save all the set points from a controller onto a USB flash disk and import settings into another W600 controller, and download datalog files to a USB flash disk. On screen graphing of one analog signal and one digital signal/relay state shall be available on the touchscreen display.
