MR Modulo Adjustable Constant Airflow Regulator 2 MR Modulo – 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 under- ventilation (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. Actual operating airflows are often far from the original HVAC system design. Accurate balancing is nearly impossible with traditional balancing dampers. A system may start out balanced, but it is susceptible to pressure fluctuations. Maintaining system balance requires constant adjustments, which are costly and time consuming. Fluctuations are unavoidable, but Aldes has a dynamic solution that preserves system balance. The Aldes MR Modulo Adjustable Constant Airflow Regulator is a passive device that automatically compensates for changes in static pressure and adjusts to maintain the specified airflow value. The MR Modulo is an elegant, cost-effective solution. It is available in 5 diameters, and each device supports at least 7 airflow rates. Twist the rotaing ring to change the airflow set-point. Then simply insert the MR Modulo into duct or fittings. No tools, no balancing, no maintenance. Buildings large and small can benefit from the MR Modulo.
