A Fan Coil Unit (FCU) is a compact and efficient air conditioning device that circulates air over a coil containing either chilled or heated water to provide localized temperature control. Commonly used in commercial buildings, hotels, hospitals, and residential spaces, FCUs offer flexible zone-based heating and cooling. Some models also support Direct Expansion (DX) systems by utilizing refrigerants, making them suitable for a variety of HVAC applications.
Designed for performance and adaptability, FCUs come in several configurations including standard, high-velocity, low-profile, and heat recovery models. Their advantages include individual room temperature control, energy-efficient variable-speed fans, and low maintenance due to simpler mechanical construction. With their space-saving design and ability to integrate into false ceilings or tight areas, FCUs are ideal for both retrofit and new installations where efficiency, comfort, and ease of service are priorities.
