Cooling Towers

Evaporative cooling products minimize the energy consumption of the entire system by providing lower operating temperatures than possible with comparably sized air-cooled equipment. BAC has a large selection of evaporative cooling products to offer, each of which falls into one of these four main categories:

Cooling Towers

Cooling towers are a proven and cost-effective method of cooling condenser water loops and industrial processes. 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 cooling tower product lines.

Closed Circuit Cooling Towers

Closed circuit cooling towers keep the process fluid clean and contaminant 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 to be cooled circulates inside the coil. During operation, heat is transferred from the warm fluid in the coil to the spray water, and then to the atmosphere as a portion of the water evaporates. In addition to chiller applications and industrial process cooling, closed circuit cooling towers are often used in heat pump loops, where closed loop cooling is preferred. BAC offers three distinct closed circuit cooling tower product lines.

Evaporative Condensers

When applied to HVAC and light industrial systems, evaporative condensers provide lower condensing temperatures and compressor horsepower savings of up to 15 percent compared with traditional systems. In an evaporative condenser, refrigerant vapor is condensed in a coil, which is continually wetted on the outside by a recirculating water system. Air is circulated 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 three distinct evaporative condenser product lines.

Ice Thermal Storage

Cooling with ice thermal storage can be a cost-effective, reliable system approach to cooling offices, schools, hospitals, malls and other buildings, and provides a steady source of low temperature fluids for process cooling applications. These systems are environmentally friendly because they help lower energy consumption and reduce greenhouse gas emissions. With thousands of successful installations worldwide, BAC is the global leader in the application of ice thermal storage.
