Compact solution for low airflow velocities. Angular air terminal units for use in variable air terminal systems at low air velocities, even under unfavourable upstream conditions. For more information see: www.trox.de/en/428f30783cd80fe1. VAV terminal units in rectangular design for variable and constant volume flow systems, for supply air or extract air, in several nominal sizeGs. High control accuracy of set volume flow rates, even in unfavourable upstream conditions. Control range at least 1:10. Differential pressure measurement and control via damper blade. Tubeless differential pressure transmission through differential pressure duct in axis Air leakage with closed damper blade according to EN 1751: Class 3. Casing air leakage according to EN 1751: Class C. Ready-to-commission unit which consists of the mechanical parts and the factory mounted electronic control component. Position of the damper blade indicated externally at the control component The damper blade is factory set to open position, which allows a ventilation airflow even without control. Meets the hygiene requirements of EN 16798, Part 3, of VDI 6022, Sheet 1, and of DIN 1964, Part 4. This EPD includes the environmental data of the product series TVE-Q. The following represents a representative dataset of the most sold variant in the declared sales year (TVE-Q/300x200/EASY).
