Air fan cooler heat exchangerare usually used for a process system that have heat to remove.
They are a "green" solution compared to cooling towers and shell-and-tube heat exchangers because they do not require an auxiliary water supply. It's for a place that do not have other cooling medium such as water as a cooling medium.
They usually use an outlet temperature of 20 degrees or more. F above the maximum expected ambient air temperature. They can use the approach temperature, but often expensive then cooling towers and water-cooled heat exchangers. Figure 1 shows the working principle of a Air fan cooler heat exchangerare.
Vrcooler provide OEM&ODM air cooled heat exchanger. Finned tube type of expanding tube type are all available.
