Aldes ZRT Series Zone Register Terminals

By replacing static grilles in large central exhaust systems, the ZRT-1 model provides on-off control for on-demand ventilation. The optional model CAR-II Constant Airflow Regulator can be installed in the ZRT-1's extended duct collar to place a maximum flow limit on each terminal. Each ZRT is a combination grille, register box, control damper, and optional flow regulator. 

The ZRT-2 model can be used for combination low-flow indoor air quality ventilation and on-demand high-flow spot ventilation using the same central fan system. This is achieved by integrating a CAR-II minimum airflow controller directly into the damper sub-assembly. With the damper completely closed, the factory calibrated CAR-II will still allow steady, low-continuous ventilation during fan operation. When other ZRT terminals are opened for on-demand control of spot ventilation, the closed ZRT-2s will maintain the specified low continuous rate through the CAR-II minimum flow control. By opening the ZRT-2's control damper, the low-flow regulator is removed from the air stream, allowing either controlled or full maximum-boost ventilation.
