Get PriceRegenerative heat exchangerWikipedia
A regenerative heat exchanger or more commonly a regenerator is a type of heat exchanger where heat from the hot fluid is intermittently stored in a thermal storage medium before it is transferred to the cold fluid. To accomplish this the hot fluid is brought into contact with the heat storage medium then the fluid is displaced with the cold fluid which absorbs the heat.
