Electric Water Level Control
EVAPCO cooling towers are available with an optional electric water level control system in place of the standard mechanical
makeup valve and float assembly. This package provides very accurate control for the basin water level and does not require
field adjustment, even under varying operating conditions.
The control was designed by EVAPCO and is manufactured exclusively for EVAPCO. It consists of multiple heavy duty stainless
steel electrodes. These electrodes are mounted external to the unit in a vertical stand pipe. For winter operation, the stand
pipe must be wrapped with electric heating cable and insulated to protect it from freezing.
The weather protected slow closing solenoid valve(s) for the makeup water connection is factory supplied and is ready for
piping to a water supply with a pressure between 5 and 125 psig (35 kPa and 860 kPa).
