Open Circuit Cooling Towers
In operation, the condenser water (or process water) flows directly over the heat transfer surface of the cooling tower. As air is introduced into the tower, a fraction of this water is evaporated, cooling the remaining water. BAC offers five distinct open circuit cooling tower product lines

Closed Circuit Cooling Towers
Closed circuit cooling towers operate in a manner similar to open cooling towers, except that the heat load to be rejected is transferred from the process fluid (the fluid being cooled) to the ambient air through a heat exchange coil. The coil serves to isolate the process fluid from the outside air, keeping it clean and contaminate free in a closed loop. This creates two separate fluid circuits: (1) an external circuit, in which spray water circulates over the coil and mixes with the outside air, and (2) an internal circuit, in which the process fluid circulates inside the coil. During operation, heat is transferred from the internal circuit, through the coil to the spray water, and then to the atmosphere as a portion of the water evaporates. BAC offers three closed circuit cooling tower product lines.
The vapor to be condensed is circulated through a condensing coil, which is continually wetted on the outside by a recirculating water system. Air is pulled over the coil, causing a small portion of the recirculating water to evaporate. The evaporation removes heat from the vapor in the coil, causing it to condense. BAC offers four evaporative condenser product lines.
