what is an eru?
Wet bulb energy recovery: increase efficiency by more than 50% over a standard dry bulb exchanger. The ERUâ¢ (Energy Recovery Unit) is an innovative and technologically advanced design specifically created for applications that require high outside air capacity. The ERU is ideally suited for places with high dry bulb and relatively low wet bulb temperatures such as the Western United States and the Middle East. For applications in colder climates that require heating recovery the ERU can be customized with a ârun around coil system. 0-100% outside air.
