DC4500
Cooling Tower Controller
The 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. |

DC4000
Cooling Tower/Boiler Controller
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. |

AC4000
& 5000 Cooling Tower Controllers
These new analog cooling tower controllers bring state-of-the-art
technology to the entry-level controller market. The AC4000 is
a simple, low cost feed and bleed controller. The AC5000 features
three selectable feed options (Limit, % of Time, Flowmeter Pulse).
Both controllers feature rugged, iron vane meters and a clear,
lockable cover. |
