TVB

Trox VARYCONTROL terminal boxes type TVB is suitable for volume flow control of supply air in VAV systems. These are terminal boxes with circular inlet spigot and a larger, rectangular outlet section.

Terminal boxes are used in VAV systems with a high level of technical and acoustic requirements. Different versions allow appropriate selection of terminals to meet project-specific control requirements. The heating requirements in the outer zones of an air-conditioned building can be covered with an electric heater. The air diffusers can be connected directly to a multiple outlet box to save branch ducting and installation costs

TVR

Circular VAV terminal units for standard applications regarding the supply air or extract air control in variable air volume systems

Suitable for the control of volume flow rate, room pressure or duct pressure
Electronic control components for different applications (Easy, Compact, Universal, and LABCONTROL)
High control accuracy even with upstream bend (R = 1D)
Suitable for airflow velocities up to 13 m/s
Closed blade air leakage to EN 1751, up to class 2 (4-10), Class 3 (12,14, 16)

Optional equipment and accessories

Acoustic cladding for the reduction of case-radiated noise

TFP

TFP Series Fan VAV Terminal Boxes take primary and induced air and mix the two thoroughly to provide a constant air supply to the occupied zone of the building.

Total flow from the diffuser is kept substantially constant thus giving very good air distribution even with high turn down of the primary air volume. TFP has been designed and developed to achieve lower room noise levels
