1239595 CONTROLLER 140 KIT W/185 & T

The control of the water treatment in a cooling tower should be simple. The key parameter to control is the concentration of dissolved solids, which we do through the control of the water conductivity. The Lakewood model 140 is a simple as that. Simplicity drives reliability and ease of operation. Connect a water meter and now you can feed the chemicals based on water flow. Blowdown valve, water meter, flow switch, and pumps are sold separately.

  • Removable power cord and receptacles for simple conduit installations.
  • Scheduled feed, which can use two relays .
  • One (1) water meter input, conductivity input, flow switch input, and 4-20 mA output are all standard features.
  • Designed with a single circuit board for better reliability and lower cost.
  • Large open shallow enclosure for easy wiring.
  • The enclosure is rated NEMA 4X.
  • Power selector switch for 115 or 230 vac operation.
  • Heavy-duty stainless steel domed numeric keypad and illuminated graphical display allow for quick and easy programming. Steel domed switches improve the tactile sensing and life expectancy of the keypad.
  • LED indicators for power, alarm and relay status.

 

  • Easy to program with the Lakewood plain English, intuitive, and user friendly menu interface.
  • Single circuit board design improves reliability.
  • No add-on options. 4-20 mA output and biocide features are standard.
  • Multiple methods of chemical feed for application flexibility.
