Trane VariTrac Dampers

Trane VariTrac dampers are designed to provide precise and reliable airflow control in a variety of HVAC applications. They are ideal for use in variable air volume (VAV) systems, where they can be used to modulate airflow to meet varying cooling and heating loads. VariTrac dampers are also well-suited for use in smoke control systems, where they can be used to help prevent the spread of smoke and fire.

Some of the key features and capabilities of Trane VariTrac dampers include:

  • Precise airflow control: VariTrac dampers are designed to provide precise and reliable airflow control, even at low flow rates. This makes them ideal for use in applications where precise airflow control is critical, such as VAV systems and smoke control systems.

Duct Sensor
The wall and duct-mounted carbon
dioxide (CO
2
) sensors are designed
especially for demand-controlled
ventilation zone applications. The sensor
is compatible with Trane VAV and
VariTrac
®
controllers. Long-term stability
and reliable sensing performance come
from advanced silicon based Non-
Dispersive Infrared (NDIR) technology.
When connected to a building
automation system and the appropriate
ventilation equipment, the Trane CO
2
sensors measure and record carbon
dioxide in parts-per-million (ppm) in
occupied building spaces. These carbon
dioxide measurements are typically
used to identify under-ventilated
building zones and to override outdoor
airflow beyond design ventilation rates
if the CO
2
exceeds acceptable levels.
