These controllers are for the following types of water treatment systems: boiler, cooling tower, industrial, municipal, water and waste water, pool and fountain.

DC4500 Cooling Tower Controller

LMI Milton Roy controller, DC 4500The DC4500 is a bleed and feed cooling tower controller with dual biocide timers. Standard features include; four feed modes (Feed & Bleed, % of Time, % of Bleed, Flowmeter Pulse), intermittent or continuous sampling, uS or PPM display, flow totalizer, manual test modes, temperature display, biocide cycle of 7, 14, or 28 days, biocide lockout, and conductivity or time-based biocide prebleed. Programming is simple and is accomplished with only three keys. The backlit liquid crystal display and LEDs provide a visual indication of operating conditions and equipment status. DC4500 PDF.

DC4000 Cooling Tower/Boiler Controller

LMI Pumps Cooling Tower Boiler Controller dc_4000 The DC4000 may be programmed as a bleed and feed cooling tower controller or boiler controller. Standard features include; four feed modes (Feed & Bleed, % of Time, % of Bleed, Flowmeter Pulse), intermittent or continuous sampling, uS or PPM display, flow totalizer, and manual test modes. The boiler mode includes a time-trap sampling method that prevents the flashing problems that are so common in boilers. Programming is simple and is accomplished with only three keys. The backlit liquid crystal display and LEDs provide a visual indication of operating conditions and equipment status.

DP5000 pH Controller

LMI Milton Roy controller, DP5000, DP 5000The DP5000 pH Controller is designed for a variety of industrial pH applications including water treatment, metal finishing, PCB manufacturing and waste treatment. It provides on/off or proportional (pulse) control of metering pumps for addition of acid or base. Level and flow inputs and alarm outputs are standard. An advanced menu includes special features such as the solenoid dump valve control for batch treatment and a “Point 3” (inflection point) adjustment for fine tuning the control profiles of the metering pumps. 4-20mA output is optional.
