Coil Banks

For applications requiring large volumes of air, most engineers and contractors to prefer using multiple coils instead of trying to use one very large coil. There can be anywhere from just two coils stacked to multiple banks utilizing four coils high x two banks wide. Each coil requires its own drain pan, and there is a primary drain pan underneath and / or downstream of the bottom coil. All the condensation from the upper coils is directed into the primary drain pan.
