Principle of operationClosedcircuitcoolingtowersorfluidcoolersoperatejustliketheopentype,butdissipatetheprocessfluidheatloadintotheambientairviaaheatexchangecoil.Thisisolatestheprocessfluidfrom the outside air, keeping it clean and free of contamination in a closed loop and creating 2separatefluidcircuits:• An external circuit, in which spray water circulates over the coil and mixes with

the outside air.• Aninternalcircuit,inwhichtheprocessfluidcirculatesinsidethecoil.During the evaporative cooling operation, heat goes from the internal circuit, via the coil to the spray water, and then to the open air as a portion of the evaporating water.

Benefits• Contaminant-free cooling circuit• Dry operation in winter• Reduced system maintenance• Lower overall system costs thanks to year-round savings on maintenance, water, energy and water treatmentA unique benefit for all BAC closed circuit cooling tower customers:• the patented Baltibond hybrid coating

Configurations

Fan systems

Counterflow configurationWater down

Centrifugal fan• can overcome external static

pressure, suitable for indoor installations

• inherently quiet

Axial fan• low energy usage

Forced draft• rotating air handling components are located on the air inlet

face at the base of the tower• easy access for maintenance• located in dry entering air stream Induced draft• rotating air handling components are mounted in the top

deck of the unit• minimal impact of fan noise• maximum protection from fan icing• located in the corrosive saturated discharge air stream
