Sometimes simpler really is better – and the Model 140 Cooling Tower TDS Controller provides basic cooling tower automation. Featuring three output relays (typically one for bleed and two for chemical feeds), the 140 uses simple-to-follow programming to make your on-site time efficient.

Inputs include conductivity, one flow switch, and one water meter. The NEMA 4X enclosure opens wide for easy wiring and troubleshooting.

The Model 140 controller for cooling towers can control conductivity plus two chemical feeds.

Controller inputs include one water meter, conductivity, and one water flow sensor switch. The three output relays are rated at 3 amps each with a total of 10 amps maximum. Further, there is a 4-20 mA output you can use to send the system conductivity to a monitoring system.

Available as the controller alone, or configured with conductivity, water flow sensor switch, plumbing, or on a mounting plate, Lakewood makes your job easier. System setup is easy using the menus already on board, with simple directions and options. Blowdown your system with setpoint control, and manage the other relays based on blowdown percent, water meter inputs, or even biocide feed schedule with up to six feeds programmable. Further, relays 2 & 3 can be programmed as alarm relays to notify you in case of an excursion.
