High Static Fan Coil Unit (FCU)

What is a High Static Fan Coil Unit?

A High Static Fan Coil Unit (FCU) is a chilled water air conditioning unit specifically designed to deliver conditioned air through long and complex duct networks. Unlike standard fan coil units, high static FCUs generate greater external static pressure (ESP), making them suitable for large commercial buildings where air must travel long distances.

These units are commonly used in shopping malls, hotels, hospitals, airports, commercial complexes, and industrial facilities where powerful airflow and uniform cooling are essential.

How Does a High Static Fan Coil Unit Work?

A High Static FCU uses chilled water flowing through a high-efficiency cooling coil to remove heat from indoor air. A high-static centrifugal fan then distributes the conditioned air through ductwork, ensuring consistent airflow across multiple zones and long duct runs.

The higher static pressure capability allows the unit to overcome resistance from filters, duct bends, air diffusers, and extended duct systems while maintaining optimal airflow performance.
