Annular groove graphite heat exchangers (interchangers) are especially adapted to the heating or cooling of ultra-corrosive liquid chemicals. This specific design allows for heat recovery between two ultra-corrosive fluids. Annular grooves are machined into impervious graphite discs to form the process and service channels. Heat is transferred by conduction through the graphite left between the process and the service channels. Annular groove graphite heat exchangers consist of a stack of graphite discs that are fused together.

Graphite block heat exchangers are adapted to the heating, cooling, evaporation, condensation and absorption of highly corrosive liquid chemicals. This design is one of the most versatile type of impervious graphite heat exchangers. Rows of holes are drilled through graphite blocks both horizontally and vertically to form the process and service channels. Heat is transferred by conduction through the impervious graphite left between the rows of holes which separate the mediums being used. Graphite block heat exchangers consist in a stack of blocks encapsulated in a steel shell.
