    Modular Fan-Cube System Makes Retrofit in Confined, Hard-to-Reach Space Easy

    At the Hilton San Francisco Union Square hotel, a 1960s-era multizone air handler was beyond its recommended service life, and maintenance requirements were increasing. Additionally, the economizer dampers, zone dampers, and linkage were rusted. Deteriorating and corroded cooling-coil and steam-coil surfaces reduced system cooling and heating performance, making the constant-volume system far less efficient over time....More
