Fan Coil Unit's Secret to Perfect Comfort: How Cooling Coils Fine-Tune Your System

Precision Cooling with Performance You Can Trust
AIR TREE Fan Coil Units (FCUs) are engineered for modern buildings demanding precise climate control, low noise, and compact design. Available in Single Skin, Double Skin, and BLDC Motor variants, AIRTREE FCUs offer energy-efficient and space-saving solutions for commercial, institutional, and hospitality applications. These units deliver reliable cooling and heating while seamlessly integrating with VRF/VRV and chilled water systems.

The Heart of Cooling: The Fan Coil Unit Cooling Coil

The Fan Coil Unit cooling coil, or simply the FCU cooling coil, is where the critical task of temperature reduction takes place right at the point of use. As warm room air is drawn in and passes over the finned surface of the coil, chilled water circulating inside absorbs the heat, effectively cooling the air before it is quietly returned to the space.

Beyond cooling, this coil is a crucial tool for dehumidification. When the air's temperature drops below its dew point, excess moisture condenses onto the coil surface. This condensate is collected and drained away—an essential function for maintaining optimal indoor humidity levels and preventing that sticky, uncomfortable feeling.

Air Tree HVAC prioritizes the construction of these coils. We utilize high-grade materials, typically copper tubes and aluminium fins, selected for their superior heat transfer efficiency and resistance to corrosion. Proper coil sizing ensures efficient thermal exchange without creating excessive air pressure drop, which would force the FCU fan to work harder and reduce efficiency.

Introducing the Fan Coil Units: Advanced Air Refinement

While the FCU's built-in filters handle standard particulate matter, specialized conditioning is sometimes required for truly pristine or precisely controlled air. Air Tree FCUs serve as environmental conditioning systems that use cooling coils to maintain cooling, humidification, or dehumidification in the air.

As an FCU manufacturer, Air Tree HVAC designs its systems with precision—where water inside the coils supports air treatment:

• Cleaning: Dust, fine particulates, and soluble gases adhere to moisture, helping purify the air as it passes through.
• Humidity Control: By precisely regulating the temperature of the circulated water, the system can add moisture (humidification) to combat dryness or remove moisture (dehumidification) from the airstream.
• Evaporative Cooling: In warm, dry environments, the evaporation process within the unit enables highly energy-efficient sensible cooling.

For sensitive applications—such as laboratories, specialized manufacturing areas, or critical data room environments—the precise air quality and humidity offered by advanced FCU systems becomes an operational necessity.
