AIO Control Panel IOM User Manual
The Marley AIO cooling tower control panel combines the cooling tower fan motor VFD along with other optional circuits i.e. water level and basin heater controls into a single enclosure feed by a common main circuit breaker.
Integrated Advanced Basin Heater Controls
The Marley ABHi integrated basin heater package controls the ON and OFF operation of the basin heater device providing freeze protection in the cold water collection basin of a cooling tower.
Cooling Tower Performance vs. Relative Humidity
Ignoring any negligible amount of sensible heat exchange that may occur through the walls (casing) of a cooling tower, the heat gained by the air must equal the heat lost by the water. This is an enthalpy driven process.
