- Model 1575e - Cooling Tower Controller

From

0

The Model 1575e uses the latest in microprocessor capability, giving the user a high level of application flexibility. A large illuminated graphics screen, multiple inputs, and very easy setup characterize this new technology. The Model 1575e is ETL approved. Cooling Tower Water Treatment Controller, Including Flow Switch Plumbing and Conductivity Sensor On A Mounting Plate

FEATURES

  • Removable power cord and receptacles for simple conduit installations.
  • Scheduled feed, which can use three relays for biocides or other chemicals.
  • Two (2) water meter inputs, two (2) drum switch inputs, conductivity input, a flow switch input, a 4-20 mA

output, and a 4-20 mA input are all standard features.

  • The 4-20 mA input can be used with a transmitter for one of the following: remote conductivity, makeup

conductivity, pH, ORP, percent, pressure, milliamps, flow rates, or traced chemistry control. This transmitter

can be added in the field.

  • Designed with a single circuit board for better reliability and lower cost.
  • Large open shallow enclosure for easy wiring.
  • Ball valve delay feature allows accurate control of motorized ball valves.
  • 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.

 BENEFITS

  • Easy to program with the Lakewood plain English, intuitive, and user friendly menu interface.
  • Controller can be used in boiler, cooling tower, or condensate applications when used with the appropriate conductivity sensor.
  • Single circuit board design improves reliability.
  • No add-on options. 4-20 mA output and feed schedule clock features are standard.
