Coil Heat Exchanger

A coil heat exchanger has separate liquid coils in the supply air and the exhaust air respectively. A heat carrier is pumped around a circuit between the coils, the air heats the liquid in the extract air coil and the liquid, in turn, heats the air in the supply air coil.The spiral-shaped tubular heat exchanger is a compact unit that can be inserted into a steam or superheated water system, for the production of DHW.A coil heat exchanger is a type of heat exchanger, a device used to transfer or exchange heat or thermal energy with the help of coils.Heat exchangers are used to transfer heat from one medium to another. These media may be a gas, liquid, or a combination of both. The media may be separated by a solid wall to prevent mixing or may be in direct contact. Heat exchangers are required to provide heating and/or cooling to meet a process requirement.
