Ephoca OSMO Vertical Stack Fan Coil units are designed for floor-to-floor stacking with vertical supply and return risers, making them ideal for hotels, apartments, condos, dormitories, and senior living buildings. Fully assembled and factory-piped with controls and risers, OSMO reduces installation time, labor, and material costs. Its ultra-compact footprint allows seamless integration into walls, columns, or closets—without costly horizontal piping. A slide-out or fixed coil pack provides easy service access, even in tight spaces, and units are available with a fresh-air inlet or built-in ERV. With one of the smallest footprints in the industry and extensive customization options, OSMO installs faster and avoids the compromises and coordination costs of standard fan coil units.
