VAV Diffuser

For applications that require system simplicity, proven technology, and superior comfort, specify the Titus T3SQ series of VAV diffusers.

• Variable geometry diffuser design maintains jet velocity at all flow rates, varying airflow pattern for optimal performance
• Separate cooling and heating setpoints on thermal T3SQ
• Supply air temperature provides automatic cooling/heating changeover on configurations -4 and -2
• T3SQ-2, digital, can control up to 14 drones
• Optional electric inlet heater for applications requiring supplemental heat (T3SQ-2 only)
• Provides accurate, personal environmental temperature control to improve productivity in the office environment
• Superior air distribution performance provides greater entrancement, higher Air Diffusion Performance Index (ADPI), and better ventilation effectiveness for Indoor Air Quality (IAQ)
• Lower cost per zone of control than typical VAV terminal with separate diffusers
• Renovate existing offices or add zones in problem areas to solve individual comfort problems
• Constant volume systems can easily become multi-zoned VAV systems for “big building comfort” on a small building budget
• Easy and inexpensive to relocate zones, ideal for use where office space may be reconfigured periodically
• Easy to install and operate
• Unique center induction on thermal T3SQ-4 ensures accurate readings even at low flows

CONSTANT VOLUME SYSTEM APPLICATION OPTION

The Titus T3SQ system is ideal for use with a constant volume system. The T3SQ gives all the advantages of a VAV system at low-pressure conditions and reduced installation costs. The T3SQ is a low pressure, pressure-dependent, variable air volume (VAV) system. The T3SQ is designed to operate around 0.15”- 0.20” inlet pressure. This system provides zoned comfort, which is not always possible with a typical constant volume
system.

1. It is recommended that a static pressure controller such as the Titus ZECV/ZQCV be installed into a constant volume system when more than 30 percent of the system airflow is put under the control of T3SQ diffusers. This minimizes the possibility of delivering excess air when a portion of the T3SQ is operating at part load conditions.
2. When an entire constant volume system uses T3SQ zone control, a ZECV/ZQCV box should be implemented. The Titus ZECV/ZQCV pressure control terminal should be sized for 80 percent of the total supply flow, less the airflow of the smallest zone.
3. Care must be taken when sizing and installing a ZECV/ZQCV. The unit should be installed as far downstream from the fan as it is practical to maximize supply and return air mixing. This reduces the risk of the unit cycling on high or low.
