MR Modulo Adjustable Constant Airflow Regulators

American Aldes MR Modulo Adjustable Constant Airflow Regulators are modulating orifices that automatically regulate airflows in duct systems to constant levels.

The passive control element responds to duct pressure and requires no electric or pneumatic sensors or controls. The MR Modulo compensates for changes in duct pressure caused by thermal stack effect, building pressure, dust-clogged filters, etc. The MR Modulo also provides a low-cost solution to balancing forced-air systems for heating, air conditioning and ventilation, eliminating the need for on-site balancing.

The active control element is a flexible bulb that inflates and deflates in response to the static pressure difference across the control. This operation regulates the free-area opening through the control, resulting in maintenance of velocity and specific airflow set points. Each diameter of MR Modulo is available in multiple factory-calibrated set points. Field adjustment is achieved by twisting the integral rotating ring to the desired set point. No tools are required.

Pressure Range: 0.2 to 1.0 in. w.g. (50-250 Pa)
Available Diameters:  4″, 5″, 6″, 8″, 10″
Airflow Range: 10-385 CFM
Use: Exhaust or Supply Air
Application: New Construction or Retrofit
Duct Type: Round

Balanced airflow with a twist

Airflow balancing is the key to a properly commissioned HVAC system.

A balanced system does not suffer from over-ventilation (noise, high temperatures, high energy consumption) or underventilation (poor air quality and uncomfortable temperatures). In tightly built structures, ventilation and air conditioning systems are specifically sized to guarantee that the proper amounts of air exit and enter the building.

How it Works

Constant airflow is achieved by the inflating action of the MR Modulo’s bulb.

At minimum static air pressure, the bulb is deflated and has a shape similar to an hourglass. As the static pressure increases across the bulb, it inflates, thereby reducing the free area around the bulb. At the same time, the higher static pressure increases the air velocity, resulting in CONSTANT AIRFLOW. This occurs regardless of pressure differences in the range of 0.2 to 1.0 in. w.g. (50 to 250 Pa). The air velocity in the duct is in the range of 60 to 700 ft/min. (0.3 to 3.5 m/s).

Thermaduct Provides High Quality Duct Systems

 

Thermaduct™ is a pre-engineered duct system that incorporates the duct, insulation and cladding all in one high-performance product.

The duct system is available in a variety of thicknesses that supply R-8 through R-24 insulation value. While other manufacturers use tapes, adhesives and screws, which experience degradation over time, Thermaduct™ uses a patented heat or chemical welded seam to ensure impervious water and air integrity.
