ZRT VentZone® Systems
VentZone® Systems by Aldes combine model ZRT demand-controlled zone register
terminals and Heat Recovery Ventilators (HRV) or Energy Recovery Ventilators (ERV) to
create the most advanced home ventilation solution. Zone Register Terminals (ZRT) replace
individual fans or static grilles, which control the fan so that areas are only ventilated as
desired. Also known as demand-controlled ventilation, controlling the airflow on a zone-
by-zone basis saves energy and reduces the load on heating and cooling systems.
Each ZRT is fitted with a self-balancing constant airflow regulator that allows controlled
amounts of continuous IAQ ventilation when the damper is closed. The primary flow
damper opens when called upon by
any switch, timer, dehumidistat, or
occupancy sensor. Once the damper
is opened, the ZRT signals the HRV
or ERV to boost speed and airflow
from the open ZRT, making it ideal
for residential bathroom ventilation.
Aldes VentZone® Zoned IAQ with
Heat and Energy Recovery Kits
include a Standard Residential Series
Heat Recovery Ventilator (HRV) or
Energy Recovery Ventilator (ERV) and a combination of Zone Register Terminals (ZRT®)
for continuous IAQ exhaust and on-demand boost exhaust during bathroom occupancy.
