eFlow USA is proud to supply hundreds of eFlow-CAR Dual Flow (Motorized) Regulators for the highly anticipated new-construction luxury development at The Daymark at Edge-on-Hudson in Tarrytown, NY. This ZRT alternative solution allows for two controlled CFM settings. The premier waterfront project features 100 high-end condominiums and townhomes across 5 stories. The project team includes COOKFOX Architects (Project Architect), CMD Group (General Contractor), and LL Parcel H, LLC (Developer). eFlow USA worked directly with the installing contractor, Premier Comfort Inc., to deliver this massive scope.

Elevating Luxury Waterfront Living
High-end residential developments require ventilation solutions that match their luxury status. Our eFlow-CAR Dual Flow Regulators provide exactly that. By utilizing a 24-volt motorized system, these regulators automatically shift between a minimum continuous airflow and a maximum boost airflow, ensuring superior indoor air quality and elite energy efficiency.
