Chilled Water Coil – Emergent Coils

Chilled Water Coil – Emergent Coils

Chilled water coils also known as hydronic cooling coils are typically used to cool or remove moisture from air streams. The air to be cooled moves through the fins, and either water or an ethylene or propylene glycol solution move through the tubes. This is a type of heat exchanger mostly used in commercial and industrial air handler units.
