The Murray, New York, NY

Revolutionary eFlow-Constant Airflow Regulators installed at The Murray Luxury Residences

New York City’s skyline welcomes a new icon of modern luxury living with the completion of The Murray, located at 509 Third Avenue. This architectural marvel, standing tall at 36 floors, houses 171 opulent rental units across its expansive 166,917 square feet. The Murray stands as a testament to contemporary design, offering an unparalleled lifestyle experience for its fortunate residents.

At the heart of The Murray’s commitment to excellence lies the integration of eFlow-Constant Airflow Regulators. These innovative devices introduce a new era of air balancing, indoor air quality and energy efficiency. The 4″ CARs (Constant Airflow Regulators) with a 10-30 CFM range play a pivotal role in maintaining automatic airflow balancing. This ensures that every resident enjoys consistent and high-quality airflow, contributing to a healthier and more comfortable living environment.

The benefits of eFlow-CARs extend beyond just comfort. By optimizing airflow and minimizing energy waste, The Murray not only offers luxury but also aligns with sustainable living practices. The incorporation of eFlow’s Constant Airflow Regulators results in reduced energy consumption, lower utility costs, and an overall greener footprint for the building. This investment in advanced airflow management is a testament to The Murray’s commitment to both resident well-being and environmental responsibility.

The Murray was designed by Ismael Leyva Architects, developed by  Kahen Properties LLC and Lalezarian Properties LLC.  Charlton Development Group is the the general contractor.

The manufacturers representative, SRS Enterprises, Inc,  facilitated the sale of eFlow products for this project.

The installation of eFlow-Constant Airflow Regulators was made possible through the expertise of Versatile Mechanical Services and JAG Air Conditioning Corp. This collaboration ensures that the innovative airflow management system seamlessly integrates into The Murray’s state-of-the-art infrastructure.

In a world where luxury, comfort, and environmental responsibility converge, The Murray sets a remarkable standard. Its investment in advanced airflow technology not only enhances the lives of its residents but also paves the way for a greener and more energy-efficient urban landscape.
