Single Duct VAV Boxes Type ‘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
