Duct Coil

A duct coil is a type of heat exchanger that is used to transfer heat from one medium to another. It is commonly used in HVAC systems to transfer heat from air to water, or vice versa. The coil consists of a series of tubes, typically made of copper or aluminum, that are bent into a coil shape. The tubes are connected to a series of fins that are designed to increase the surface area of the coil and increase the rate of heat transfer. The air or water is then passed through the coil, allowing the heat to be transferred from one medium to the other. Duct coils are highly efficient and can be used to both heat and cool a space. They are also relatively easy to install and maintain, making them a popular choice for many HVAC systems.
