COMPONENT DESCRIPTION
2.5 ENTHALPIC CORE
Each EV Premium has a static-plate, cross-flow core separates the outgoing, polluted indoor
airstream from the incoming fresh airstream—while simultaneously transferring total energy
(heat and water vapor) between the two. Airstreams do not mix, and pollutants are not
transferred across partition plates.
NOTE: The cores
used in all ERVs
are static plate
enthalpic cores. They are
commonly referred to in
this manual as “cores.”
