DDV Dual Duct Terminal Unit
Terminal Units
A flexible solution which offers one terminal for both interior and exterior zones, the DDV Dual Duct Terminal Unit saves you the additional cost of reheat coils. It delivers variable or constant volume air for maintaining a constant space temperature, depending upon the control sequence.
- Patented Flo-Cross® Sensor which features 24-point upstream and downstream sensing with center averaging chambers and exclusive amplification wings
- Insulated lining provides sound dampening and thermal resistance
- A wide variety of sizes are available, resulting in a total flow range of 45 to 4200 CFM
Product Application
Model DDV is an ARI-certified terminal unit designed to provide greater space comfort and maximum indoor air quality. It is equipped to draw cool air from outside into one of the primary inlets and warm plenum air into the other inlet. This helps significantly reduce energy consumption. It can be used for both interior and exterior zones and saves you money on additional reheat coils. The integral discharge attenuator allows the unit to be used in critical sound applications.
Features
- Heavy-duty 22-gauge casing construction
- Industry-standard round inlet collars sized to accept either flexible or rigid duct
- The DDV features two primary inlets, one for hot air and one for cold air, each having an integral independent damper. The cold air inlet is commonly known as the "cold deck" and the hot air inlet is known as the "hot deck"
- Offers a Slip and Drive connection on the discharge plenum
- The integral discharge attenuator allows for the DDV to be used in critical sound applications
- DDV terminals can be furnished without controls, with electronic analog controls, with factory-mounted direct digital controls (supplied by others), or with four function pneumatic controls
- A variety of insulations/facings are available depending on the level of erosion protection required
- ARI-certified performance data
- Unequal inlet sizes (see submittal for available combinations). The casing is determined by the largest inlet size
- Internally lined casing utilizes 1/2” thick, dual-density fiberglass insulation. Insulation meets or exceeds the safety and erosion requirements of standard UL 181 and NFPA 90A
- Two-piece solid damper shaft that features a position indicator for easy identification of damper angle discharge plenum
- Low mixing applications require the use of the basic DDV and those applications requiring a higher level of temperature mixing benefit from the use of the optional mixing baffle
- 20-gauge construction is optional
- Enviroseal™ engineered foam polymer insulation provides superior erosion resistance, making it an excellent option for fiber-free applications
- Total Air Sensing bulkhead features the patented Flo-Cross® Sensor
Benefits
Economical and Efficient
Save more energy by using the economizer to pull in cold air from outside, as compared to cooling air via compression.
Minimum Leakage
Damper blade is made of elastomeric gasket, which acts as a powerful seal to prevent air leakage for quality performance.
Versatile Design
Comes with a multitude of sound insulation options that add superior erosion resistance for use in fiber-free applications.
