8415.82.01.35 - Central station air handlers

This classification covers central station air handlers, a type of air conditioning machine designed for large-scale environmental control within commercial, industrial, or institutional buildings. These units are characterized by their central installation and typically house the primary air handling components, including a motor-driven fan for air circulation, and elements for altering both the temperature and humidity of the air. They are specifically designed to be integrated with a water chiller system, which provides the cooling medium.

Distinguishing this category from its sibling, "Room fan coil units" (8415.82.01.30), is crucial. While both are part of the broader air conditioning machinery family, central station air handlers are distinct in their design and purpose. Fan coil units are typically individual room or zone units that contain both a fan and a coil (for heating or cooling) and are not necessarily integrated with a central water chiller in the same way as the units classified here. The "Other" sibling category (8415.82.01.40) would encompass air conditioning units that incorporate a refrigerating unit but do not fit the specific description of central station air handlers for use with water chillers.

As this is a leaf node within the HTS, there are no further subdivisions. Therefore, classification within 8415.82.01.35 relies on confirming that the unit is an air handler, it incorporates a refrigerating unit, it is designed for central station application, and it is intended for use in conjunction with a water chiller system. The presence of a motor-driven fan and elements for temperature and humidity control are fundamental requirements.
