Annular groove graphite heat exchangers

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.

Conception

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.
