Regenerative heat exchangers (RHX) find widespread applications in liquid food or pharmaceutical processing as well as in reaction engineering. Whereas \"large\" RHX systems have been in use for a long time, their smaller micro-channel counterparts are a more recent area of interest.

Here, we describe the design and development of a novel micro-channel counter-current regenerative heat exchanger to thermally process a liquid stream with an exceptionally high heat recapture efficiency. The design consists of stacks of shallow inlet/outlet channel pairs and is shown to be capable of thermally sterilizing a water stream by cycling its temperature from ambient and ~ 130 C with 98% regenerative energy recapture in a compact device that requires very low energy input.
