Recuperators with ceramic heat exchanger

Ceramic

— one of the distinguishing features of ceramic recuperators is that they use not only the apparent but also the latent heat of the exhaust air — in other words, they provide heating not only due to the temperature difference but also due to the condensation of the moisture contained in the exhaust air. Ceramic heat exchangers have high efficiency — from 90%, but they are not cheap and do not return moisture — in the cold season air humidification may be required.
