Air cooled heat exchangers (dry cooling) are often a preferred cooling application for power plants, refineries, oil & gas, chemical industries, and HVAC-R systems.
A traditional problem with air-cooled heat exchangers is noise. Noise emission legislation has become increasingly strict as industrial zones and residential areas have grown closer to each other. At the same time, public awareness and intolerance of noise in the workplace has increased.
Cooling fans are often identified as the dominant source of air cooled heat exchanger related noise. To solve this problem, Howden has dedicated many years to the continuous development of cooling fans with unequaled ultra-low noise characteristics.
