Diffuser Pressure Independent Terminal Units
Flow Tech diffuser 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 air flow 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 Diffuser PITUs consist of a casing with circular inlet spigot, rectangular outlet connection. Circular damper blade and cross flow differential pressure sensor for measuring air volume. The casing design and optimized silencer geometry reduce self generated noise, minimize pressure drop.
Diffuser PITUs also incorporate control components (VAV actuator, transformer) which are factory fitted and calibrated in our in house calibration rig to ensure all DPITU meet the design criteria of our customer. This enable the terminal to monitor desired air flow rate as dictated by the thermostat or input signal of 0-10V and compen sate 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.
Features:
- Circular damper blade for better flow management
- EDPM gasket on damper blade for low leakage.
- Multi-point averaging inlet differential pressure sensor
- Acoustic lining of mineral wool with glass fiber facing suitable for air velocity up to 20m/s.
- Shaft indicator for damper position.
- Rectangular discharge outlet with clip and drive cleat duct connection.
- Control components encased in control panel (optional).
