The Triatek VAV-1000L Volumetric Offset Controller is a VAV controller that provides variable air volume control in laboratory zones that require pre-determined offsets between supply and exhaust air.
Applications include:
- Temperature control
- Room exhaust air control
- Room supply air control
VAV controllers are an integral party of Triatek’s Laboratory Solutions. The VAV-1000L reduces laboratory energy consumption, improves indoor air quality, and provides building automation flexibility.
The VAV-1000L works by communicating with the HMS-1655 Fume Hood Controller. The exhaust cubic feet per minute (CFM) from fume hoods and general exhaust from the lab are summed by the VAV-1000L to calculate total exhaust CFM, which is subtracted from the supply airflow CFM to calculate net airflow for the lab.
Where net negative pressure for containment purposes is required, the VAV-1000L modulates supply airflow to be less than the total exhaust airflow. The VAV-1000L constantly monitors conditions and adjusts airflow by modulating the Venturi valve or damper in order to maintain the desired negative pressure. Zone temperature can also be controlled using a temperature transmitter.
