DC4500 Cooling Tower Controller
  • 4 Programmable inhibitor feed options
  • Dual Biocide Control
  • 0 - 20,000 uS (conductivity) range
The DC4500 is a feed and bleed cooling tower controller with dual biocide times. 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.

DC5500 Cooling Tower Controller
  • Microprocessor-Based Cooling Tower Controller
  • Includes all features of DC4500 plus more
  • Includes serial port for downloads
The DC5500 has all of the features of the popular DC4500 Controller; dual biocides & inhibitor pumps control, 0-20,000mS conductivity range, four feed modes, etc...

The DC5500 also has the additional features of a second water meter input, three tank level inputs, and most importantly- communications capabilities to download historical data, view real time conditions, and program the controller remotely.

Each DC5500 has an RS232 serial port for data downloads into a PC or Palm Pilot™, or for quickly programming the various controller settings with a computer in a user-friendly pull-down menu format. Up to (31) DC5500 Controllers can be linked to a single LiquiComm Communications Module for remote communications on a standard analog phone line.

The DC5500 can be used with a LiquiComm Communications Module and the LMI DataComm Software as a complete information management system for remote cooling tower accounts.

DC4000 Cooling Tower/Boiler Conductivity Controller
  • 4 Programmable inhibitor feed options
  • 0 - 20,000 uS (conductivity) range/cm control range
  • Solenoid or motorized valve control
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 Cooling Cooling Tower/Boiler Conductivity Controller
  • 0-14 pH scale
  • Single and Dual Point Calibration
  • pH Programable Response Delay
The 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.
