VARYCONTROL


Air terminal units for supply or extract air for a variety of applications

Units of the VARYCONTROL types are air terminal units for supply and extract air systems. They can be used for almost any control, regulation and shut-off tasks in room air conditioning systems. The selection of the type of units is based on the acoustical requirements and the control functions.

Type TFP

Series Fan VAV Terminal Boxes 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.

Type TVB

VAV Terminal Boxes 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
