Cooling Controller Lakewood 1575e pre-installed and wired, with TRACED sensor p/n1269338


Lakewood 1575e Cooling controller, with cond sensor, flow switch, TRACED sensor and rig exit piping, installed and wired on a PVC panel (12"x21") p/n 1269338

Ready to go; controls the water quality through conductivity measurement and blowdown valve relay. It can also control three chemical pumps through water meter signal or, process signal like a pH or ORP signal sent by other instrument or, Lakewood upgrade option.

The Model 1575e uses the latest in microprocessor capability, giving the user a high level of application flexibility. A large illuminated graphics screen, mul- tiple 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

• 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.


• 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.
