The main feature of spiral heat exchangers lies in the incredibly long "heat line" formed by two mutually twisted spirals of plates, separated by small columnar stops, forming a channel of the required cross-section. This design allows to operate these devices with different technological media: with a high degree of viscosity, with the content of mechanical or fibrous inclusions, various pulps, dispersed solutions.
In addition, the heat transfer capacity of the spiral heat exchanger is phenomenal, which makes it possible to use them in systems of heating or cooling of working media with very small difference of initial and final temperatures. They are compact and easy to clean.
