Balancing supply and exhaust airflows in high-rise buildings, hotels, nursing homes, and offices can often seem like a daunting task. However, Aldes offers a straightforward solution with the MR Mono constant airflow regulator. This product comes set to a specific airflow from the factory, making installation easy and efficient. With its modulating orifice, the MR Mono automatically adjusts to changes in duct pressure—such as stack effect and building pressure fluctuations—without requiring any electric or pneumatic controls, effectively eliminating the need for on-site balancing.
Challenges
In my experience, maintaining proper airflow in multi-tenant buildings, especially hotels with common exhaust systems for bathrooms, poses unique challenges. Traditional methods of airflow balancing often require extensive time and labor to ensure that each exhaust system operates effectively, which can be both resource-intensive and costly.
The Solution
The Aldes MR Mono is particularly well-suited for hotel applications, where it can be utilized at each bathroom exhaust take-off. I have successfully supplied these regulators for various hotels across Ontario, including Staybridge St. Jacob’s, Holiday Inn Express Port Elgin, Holiday Inn Express Collingwood, and Hampton Inn Belleville. In each of these installations, the Aldes MR Mono is factory-set to 50 cfm, ensuring consistent and reliable performance.
Our Approach
The MR Mono achieves constant airflow through the inflation of its bulb. At minimum static air pressure, the bulb remains deflated. However, as static pressure increases, the bulb inflates, reducing the free area around it. This inflation leads to increased air velocity, resulting in consistent airflow regardless of pressure differences ranging from 0.2 to 1.0 in. w.g. The MR Mono boasts an accuracy range of +/- 3 cfm for nominal airflows below 30 cfm and +/- 10% for those above 30 cfm.
For installation, the MR Mono easily push-fits into round ductwork and should be positioned close to the take-off or terminal. It can be mounted either vertically or horizontally. Constructed from durable PC/ABS plastic, the Aldes MR Mono is also UL2043 certified for safety and performance.
Conclusion
If you require adjustable airflow control, Aldes offers the MR Modulo, which features an adjustable dial for setting desired airflow ranging from 12 cfm to 385 cfm across varying diameters. For more information about these innovative solutions, visit the Aldes website or contact O’Dell today!
