- Air cooled heat exchangers will continue to operate (but at reduced capacity) due to radiation and natural convection air circulation should a power failure occur.
- Temperature control of the process fluid may be accomplished easily through the use of shutters, variable pitch fan blades, variable speed drives, or, in multiple fan installations, by shutting off fans as required Ø Excellent for removing high level temperatures, particularly greater than 200°F.
- Maintenance generally claimed to be 1/3 or less than water coolers. Clean fins by compressed air and brushes, sometimes while operating.
Ground space often less than or equal to cooling towers; can also serve dual purpose by mounting air-cooled units above other equipment or on pipe ways or roofs of buildings. Vibration is no problem.
