Figure 45-1:

Standard water systems

Systems using tap or softened water control water

levels electronically using a three-rod probe. The

controller responds with the above actions when the

water level reaches each rod.

DI/RO water systems

Evaporative system water level control

Standard water systems require conductive water

DRI-STEEM’s standard water evaporating chambers (found in

DRI-STEEM evaporative humidifiers with model numbers that do

not end in “DI”) require fill (makeup) water to have conductivity

of at least 100 µS/cm (2 grains/gallon). These systems use a

conductivity probe to measure water levels and, therefore, will

not operate with DI/RO water (which is demineralized and not

conductive).

Important note about chloride corrosion

Corrosion can occur in evaporating chambers when chloride levels

are unusually high in the supply water. This is usually caused

by improperly maintained DI treatment beds, but has occurred

with potable water supplies. If you see stainless steel pitting, call

DRI-STEEM technical support.
