Cooling Towers

Cooling towers can range in size from fairly modest to extremely large, depending on the cooling loads of a facility. Chardon handles them all, and will tailor a maintenance program to meet your specifc needs. Due to it's exposure to the outside environment, the cooling tower is the primary source of contamination within your system. Acting as a large air washer, the "open" tower water loop accumulates airborne particulate and promotes biological growth. Through evaporation, it also concentrates mineral content. Chardon utilizes a full line of corrosion and scale inhibitors, white rust preventatives, and microbiological inhibitors to create a custom chemical plan that addresses these problems and others to keep your cooling towers running efficiently.


Cooling Tower Loop



Water is carried from the condenser to the cooling tower, where it's surface area is increased to facilitate evaporation. Some of the water is lost in the atmosphere, but the solids remain behind. When the cooled water reaches the sump, it is circulated back through the condenser, where it removes heat from the refrigerant.


Refrigerant Loop



Refrigerant is continuously cycled through the refrigerant loop. It absorbs heat from the chilled loop and is changed from a liquid to a gas in the evaporator. The compressor increases the pressure and temperature of the gas, which flows into the heat exchanger. There, the cooling tower water removes heat from the refrigerant causing it to condense back to a liquid.


Chilled water Loop



The chilled loop is actually a closed loop where water is circulated throughout the entire facility continuously to fulfill the cooling requirements of the system.
