Two Minicore energy recovery ventilators (ERVs)—enERVent models MCV500 and MCV1000—are said to exceed 50% to 60% total energy recovery effectiveness with 0.5% cross-contamination. Both feature a compact 16-in. chassis, for applications such as ceilings and small spaces. The hydroscopic resin energy recovery core has no moving parts. Heat-exchanger technology exceeds ASHRAE 90.1 standards, and the ERVs are also AHRI 1060-certified.
