For normal and high volume flow rate ranges and low-leakage shut-off. Rectangular air terminal units for standard applications in supply air or extract air systems with variable volume flow rates, suitable for low-leakage shut-off. For more infomation see: https://www.trox.de/en/vav-terminal-units/tvt-2512f87247b59aee. Rectangular VAV terminal units for variable and constant air volume systems, suitable for supply or extract air, available in 36 nominal sizes. High volume flow rate control accuracy. Ready-to-commission unit which consists of the mechanical parts and the electronic control components. Each unit contains an averaging effective pressure sensor for volume flow rate measurement and damper blades. Factory mounted control components complete with wiring and tubing. Effective pressure sensor with 3 mm measuring holes, hence resistant to contamination. Position of the damper blades indicated externally at the shaft extension. The damper blade is factory set to open position, which allows a ventilation airflow even without control; this does not apply to variants with defined safe position NC (normally closed). This EPD includes the environmental data of the product series TVT. The following represents a representative dataset of the most sold variant in the declared sales year (TVT/300x200/BCO).
