By replacing static grilles in large central
systems, the ZRT-IL-1 model provides on-
off control for on-demand ventilation. This
allows central fan downsizing and promotes
energy savings by minimizing necessary
fan horsepower and ventilation-induced
heat and cooling loads on the building. The
constant airflow regulator installed in the ZRT-
IL-1's extended duct collar places a maximum
flow limit on each terminal. The automatic
operation of the constant airflow regulator
will prevent noise and excessive energy
consumption caused by over-ventilation, as
well as fluctuations in airflow rates as total
system pressure varies.
The ZRT-IL-2 model can be used for
combination low-flow indoor air quality
ventilation and on-demand high-flow spot
ventilation using the same central fan system.
This is achieved by integrating a minimum
constant airflow regulator directly into the
damper sub-assembly. With the damper
completely closed, the factory-calibrated
constant airlfow regulator will still allow
steady, low-continuous ventilation during fan
operation. When other terminals are opened
for on-demand control of spot ventilation, the
closed ZRT-IL-2 will maintain the specified
low-continuous rate through the constant
airflow regulator minimum flow control. By
opening the ZRT-IL-2's control damper, the
low-flow regulator is removed from the air
stream, allowing either controlled (using
optional second constant airflow regulator)
or full maximum-boost ventilation.
The ZRT-IL can activate fans used in smaller
central ventilation systems. Through the use of
an integral damper end-switch, the ZRT-IL can
trigger the remote fan to start. This provides
the distinct advantage of allowing the fan
to only ventilate specific spaces when called
upon, without the need for separate fans in
each space. This is especially important in
residential bath applications using popular
in-line and multi-port fans, where low noise
and a single exterior vent penetration are
desired.
MOUNTING
The ZRT-IL includes a mounting bracket to
accommodate new or existing construction.
