Phoenix Central Station Tower East and West Phoenix, Arizona

The Phoenix Central Station Tower East and West, located in downtown Phoenix, Arizona, are two new mixed-use towers slated for completion in 2025. The 33-story and 21-story towers will feature a combined total of 362 apartments and 455 student housing units. Both towers will also be equipped with eFlow-Constant Airflow Regulators (CARs) of automatically balanced ventilation, high  indoor air quality and energy savings.

Project Background
Developed by Medistar Corporation and designed by Davis Architecture, this $245-million redevelopment spans over 1 million square feet, integrating seamlessly with the city’s transit systems. The larger tower includes 70,000 square feet of office space and a 4th-floor amenity deck, while the smaller tower focuses on student housing for Arizona State University.

Project Details
The Twin Towers will feature modern amenities and extensive parking facilities, enhancing urban living. The development targets LEED Gold certification, highlighting its commitment to sustainability and efficiency.

Stakeholders and Roles
Key contributors include:


Technical Insights
The project includes the installation of various eFlow Constant Airflow Regulators (CARs) to optimize ventilation. Products supplied through ThermAir Systems include 4”, 5”, 6”, 8”, and 10” CARs for various CFM requirements.

Benefits of Installing Constant Airflow Regulators

  • Improved Indoor Air Quality: Ensures a steady flow of fresh air, reducing indoor pollutants.
  • Energy Efficiency: Enhances heating and cooling efficiency, reducing costs.
  • Enhanced Comfort: Provides a healthier living environment for residents.

eFlow-CAR is a simple solution to balancing ventilation systems. Constant Airflow Regulator is a device that automatically regulates airflows in ventilation systems to constant levels. The passive control element responds to duct pressure, and requires no electric sensors, pneumatic sensors or controls. eFlow-CARs promote high indoor air quality and energy savings.
