Pressure Independent Terminal Units with Electric Heater

Flow Tech pressure independent terminal units are designed to control air volume flow rate for supply air on variable volume system. These units are designed to supply the airflow rate of conditioned air into an occupied zone in response to control signal from a thermostat or building management system. These could also be used as stand alone system. 

Flow Tech Terminal units consist of a casing with circular inlet spigot, rectangular outlet connection with integral 900 mm long attenuator lined with acoustic mineral insulation with black tissue facing. Circular damper blade and cross flow differential pressure sensor for measuring air volume. The casing design and optimized silencer geometry reduce self-generated noise and minimize pressure drop.

Terminal units also incorporate control components (VAV actuator, transformer) which are factory fitted and calibrated in our in house calibration rig to ensure all PITU-EH meet the design criteria of our customer. This enable the terminal to monitor desired airflow rate as dictated by the thermostat or input signal of 0-10V and compensate instantly for any changes in supply air pressure that might tend to alter the supply air volume. Net resultant is a pressure independent variable air volume system.

The complete VAV terminal/silencer assembly has been tested in accordance to AHRI 880.
