Type TCP

The TCP VAV unit is typically used in systems that require perimeter heating in winter of supplementary cooling in certain occupied zones. It consists of two major components, a primary air damper and a secondary air induction indoor fan. A pressure independent control of the primary VAV damper is accomplished by using a differential pressure grid which provides an accurate control of air flow. Mixing between the primary air and the induced warm recirculated air from the ceiling void is achieved by means of a forward-curved centrifugal fan with a direct drive motor. For winter operations, the induction fan provides an economical way of utilizing the recycled heat generated by inner zone. The fan transfers the recycled heat from inner zone to the perimeter zone utilising the returned air from ceiling void or rooms. Cycling of the fan results in energy savings as activation is only required when required in a specific zone. Placement of the fan is critical to ensure the desired occupant comfort levels. Hot water coil or electric heater for secondary heating is available. All controllers or electrical components are factory fitted and VAV controller is factory calibrated.

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

Type TFP

Series flow fan powersd terminals offer enhanced space comfort and flexibility In a wide variety of applications.

Considerable operating savings can be achieved through the recovery af waste heat,reduced central fan horsepower requirements and night setback operation.lROX Tennlnal Boxes Type ''TFP" take primary and induced air and mix the two thoroughly to provide a constant air supply to the oc­ cupied zone af the building.Totalflow to the diffuser Is kept substantially constant thus giving very good air distribution even with high turn down of the primary air volume.

A pressure independent controlof the primary VAV damper is accomplished by use af a differential pressure grid which gives accurate controlaf air flow even with a goo bend on the inlet spigot.Mixing between the primary airstr8am and the induced warm air from the ceiling void is by a forward curved blade centrifugal fan with direct drive motor.

TROX Series Fan Tenninal Boxes are eminently suitable for low temperature air applications.If the supply air tempera­ ture Is low,then the fan volume flow rate must be higher than the primary air volume flow rate to ensure suitable air temperature at the diffuser.The design af the type TFP ensures that at 100 % primary air,sulftclent Induced air Is mixed with the primary air so that the air discharged has a conventional cooling differential which will not cause draught problems In the space being conditioned.The primary air damper can also be fully shut,with 100 % recirculated or induced air.
