Advanced energy recovery ventilation - ZY Series
Indoor air quality (IAQ) is a key consideration for any business owner looking to create a
healthy and comfortable environment.
An energy recovery ventilator (ERV) provides balanced, energy efficient ventilation by transferring heat
and moisture between incoming fresh filtered air and outgoing stale air. In the winter, an ERV keeps heat
and moisture inside the building. During hot, humid summer months, it maintains cool, dry indoor air.
Recovers up to 83% of the heat in the outgoing air
ZY Series achieves more than 80% of
heat exchange efficiency in all the
line‑up 1). The high recovery rate
optimizes operation cost and can be
considered as a sustainable solution.
