Membrane energy recovery ventilation (MERV) uses a stationary, non-rotating polymer membrane core to transfer both sensible and latent heat between supply and exhaust airstreams. Unlike a rotating energy recovery wheel, a membrane exchanger has no moving parts and physically separates the two airstreams, which eliminates the carryover of moisture, odors, and particulates that can occur […]
