APOLLO Vertical Concealed Fan Coil Unit

Discreet Hydronic Comfort, Built Into the Room

The APOLLO Vertical Concealed Fan Coil Unit delivers powerful hydronic heating and cooling while keeping the mechanical equipment out of sight. Installed vertically inside a wall cavity, utility enclosure, or purpose-built cabinet, it provides conditioned air through discreet supply and return grilles—preserving valuable floor and wall space while maintaining a clean interior design.

Connected to an air-to-water heat pump, geothermal system, boiler, or chiller, the unit circulates room air across a hydronic coil supplied with hot or chilled water. The result is responsive, zone-level comfort without refrigerant lines running throughout the building.

Flexible 2-Pipe and 4-Pipe Configurations

Choose a 2-pipe configuration for a straightforward system that switches between heating and cooling seasonally, or select a 4-pipe configuration with separate hot- and chilled-water circuits. A 4-pipe system allows different zones to heat or cool independently, making it particularly well suited to hotels, multifamily buildings, offices, and mixed-use properties.

Designed for Quiet, Concealed Installation

The vertical cabinet fits into locations where a visible wall-mounted or floor fan coil would interrupt the finished space. Short supply and return ducts can be used to position the grilles where they best suit the room layout, while the concealed unit remains accessible for service and maintenance.

• Hidden installation: Keeps the fan coil body out of the occupied space
• Heating and cooling: Conditions individual rooms and building zones year-round
• Hydronic operation: Uses hot or chilled water instead of indoor refrigerant lines
• 2-pipe or 4-pipe: Supports both seasonal changeover and independent heating and cooling designs
• Quiet performance: Sound levels from 39 to 52 dB(A), depending on model
• Three available sizes: 1.5 Ton, 3.5 Ton, 6 Ton
• Flexible applications: Suitable for homes, apartments, hotels, offices, and light-commercial buildings

Three Sizes for Room-by-Room System Design

The APOLLO Vertical Concealed FCU is available in three sizes to accommodate different airflow and zone requirements. Multiple units can be connected to a shared hydronic loop, allowing each room or area to be controlled independently while operating from one central heating and cooling source.

For accurate selection, the fan coil should be sized according to the room’s calculated heating and cooling load, available water temperature, required airflow, and system configuration.
