3210

Dual Duct terminal units utilize pressure independent controls for accurate temperature and volume control. Nailor dualduct terminals are designed to precisely regulate and vary the volume of both the hot and cold deck of a dual duct system in response to thermostat demand. Many control sequences are possible with today's sophisticated controls.

Each deck can be set to reset between a minimum and maximum air volume limit with numerous possibilities for hot and cold air mixing and proportioning.

Nailor has three types of dual duct terminal units. When no mixing is required, Model 3210 may be used. Essentially, two single duct terminal units working in tandem. When blending of hot and cold air is required, the Model 3230 comes with an integral compact mixing attenuator section which provides some attenuation of discharge noise and through the use of internal baffles, mixing of the hot and cold airstreams. The compact design of the 3230 lends itself to applications where there are tight space limitations, while still meeting or exceeding industry standard sound and mixing requirements. Minimum mixing efficiency is 1 in 12. That means there is less than a 1°F (0.55°C) temperature variation at the discharge for each 12°F (6.66°C) temperature difference between the hot and cold decks.

For the most demanding applications see model 3240 "BlendmasterTM ".
