Common Applications for
Low-Noise Cooling Towers
Hospitals
Noise concerns may be paramount near medical
facilities where quiet and rest are necessary.
Universities and Office Buildings
Whenever HVAC equipment is near people, unwanted
noise may be a concern. For example, conducting a
meeting or teaching a class in a room with a noisy
cooling tower outside is an unwelcome distraction.
Hotels and Residential Areas
Hotel guests or residential neighbors shouldn't have
to contend with a cooling tower fan cycling on and
off at night, while they’re trying to sleep. At night,
ambient noise levels are lower, which may make a
cooling tower seem louder to anyone nearby.
