Ductable Ceiling Concealed Fan Coil Unit: How It Works & Where to Use It
A ductable ceiling concealed Fan Coil Unit is installed entirely above the false ceiling, delivering conditioned air through ductwork so only the grilles or diffusers are visible in the room. Jaideo Automation supplies the Daikin Ductable Ceiling Concealed Chilled Water Fan Coil Unit.
How It Works
Chilled water from the central chiller flows through the coil inside the concealed FCU. A fan draws room air up through return grilles, across the coil, and pushes the cooled air back down through ductwork to supply diffusers positioned around the space. Because the unit itself is hidden, only the ceiling grilles are visible — the HVAC equipment disappears from the interior design entirely.

Exact airflow, capacity, and noise figures vary by model — see the product page for the full datasheet.
Why Choose This Format
- Clean, equipment-free ceiling appearance — ideal where interior design matters
- Flexible duct routing lets engineers position diffusers according to the room layout, not just where the unit happens to sit
- Suitable for hotels, hospitals, corporate offices, and luxury residential projects
- Compatible with both air-cooled and water-cooled central chiller systems
Ductable Concealed vs Ceiling Exposed FCU
The concealed format trades a small amount of ceiling void space and installation complexity for a fully hidden unit. If ceiling void space is limited or a lower-cost option is preferred, a ceiling exposed FCU — visible in the room but with no ductwork required — is the alternative. See our Ceiling Exposed vs Ductable FCU comparison.
Static Pressure: Why It Matters
The static pressure rating determines how far the FCU can push air through ductwork before performance drops off. Longer duct runs or more diffusers need a higher static pressure option — see our High Static Fan Coil Unit guide for projects with extended duct runs.

To size the unit, see the FCU Sizing Guide, and for the water-side design see 2-Pipe vs 4-Pipe FCU Systems. If a wall-mounted format suits the space better, see the Hi-Wall FCU guide and the Daikin Hi-Wall FCU; for ceiling-mounted air delivery without ducts, the Ceiling Mounted Cassette FCU and Ceiling Exposed FCU. Pair the unit with a TB3 Communicating FCU Thermostat for room control.
Frequently Asked Questions
What is a ductable ceiling concealed fan coil unit?
A ductable ceiling concealed fan coil unit is a chilled water HVAC terminal unit installed above a false ceiling that delivers conditioned air through ductwork, keeping the unit itself hidden from view.
What static pressure options are available for ductable FCUs?
Ductable ceiling concealed FCUs are typically available in low, medium, and high static pressure options depending on the model, chosen based on duct length and airflow requirements.
Is a ductable ceiling concealed FCU suitable for residential projects?
Yes. It is commonly used in luxury apartments, villas, and premium residential developments where a clean ceiling appearance and flexible air distribution are priorities.
