Cooling Tower Water Conductivity Range

cooling tower water ph and conductivity control,although there are many variations in cooling tower design, a common feature is the control of water quality using ph and conductivity to maintain a given set of conditions. the conductivity level will rise due to evaporative water loss during continuous recirculation of the cooling water. this causes an increase in concentration of impurities. these impurities can phph cause corrosion and scaling that results in loss of cooling tower.cooling tower efficiency and range,the range is the temperature drop across the tower example from below data range = 95 – 85. the cooling tower efficiency can be expressed as μ = (ti – to) 100 / (ti – twb) (1) where example μ = cooling tower efficiency – common range between 70 – 75% ti = inlet temperature of water to the tower 95 to = outlet temperature of water from the tower 85 twb = wet bulb temperature of air (oc, of) 80.cooling tower conductivity controllers,-cr2 0-25 range front panel, conductivity range: 0-2,500 µs. -cr10 0-10 range front panel, conductivity range: 0-1000µs. -cr20 0-25 range front panel, conductivity range: 0-250µs. -cr30 0-5 range front panel, conductivity range: 0-500µs. enclosure options (optional).cooling water treatment 101 - conductivity - yamatho,we find that operation of cooling towers between 3 to 6 cycles is the most economical range. environmental requirements, insufficient amounts of fresh makeup water, and the usgbc leed program are additional forces driving cooling tower operation to higher cycles..

Best Management Practice #10: Cooling Tower Management

work with your cooling tower water treatment specialist to maximize the cycles of concentration. many systems operate at two to four cycles of concentration, while six cycles or more may be possible. increasing cycles from three to six reduces cooling tower make-up water by 20% and cooling tower blowdown by 50%.

COOLING TOWER GUIDELINES

COOLING TOWER GUIDELINES

water, in the form of small droplets, is often lost in the airflow leaving the cooling towers, and is called “drift”. depending on the design of the cooling tower drift eliminators, water losses through drift should be maintained below 0.002% of the maximum design water circulation rate through the tower as per as/nzs 3666:2011.

Cooling Tower Factors: Temperature, Range & Approach

Cooling Tower Factors: Temperature, Range & Approach

typically, cooling towers are designed to cool a specified maximum flowrate of water from one temperature to another at an exact wet bulb temperature. for example, a designed tower may be guaranteed to cool 10,000 gpm of water from 95°f to 80°f at 75°f wet bulb temperature. in this case, the range is 15°f and the approach is 5°f.

if there is a source of clean water entering the cooling system, the conductivity will stay low, even if the blowdown control is not bleeding and the makeup water is not entering the system. granted, the cooling tower level should steadily go up but, if the water is clean enough, it could basically just replace evaporation, keeping the conductivity low and the level steady.
