OSMO Vertical Stack

OSMO Vertical Stack unit render

Built for floor-to-floor stacking

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. Vertical Stack is fully assembled and factory-piped with controls and risers, reducing installation time, labor, and material costs. Its ultra-compact footprint allows seamless integration into walls, columns, or closets, and a slide-out or fixed coil pack provides easy service access even in tight spaces. Units are available with a fresh-air inlet or built-in ERV.

Compatible with low-temperature generators such as heat pumps, condensing boilers, and solar-integrated systems.
