Its compact, lightweight, and high-performance design provides significant advantages over traditional heat exchangers — both technically and economically.
How Microchannel Coils Work
Microchannel coils are constructed entirely from aluminum and consist of three main components: flat tubes with multiple small internal channels, ultra-thin aluminum fins, and aluminum headers. This structure ensures optimized thermal performance across all transfer points, resulting in highly effective heat exchange with minimal material usage.
Three Zones of Thermal Excellence
The efficiency of microchannel technology is rooted in its design, which enhances heat transfer in three essential areas:
Air-side heat exchange: Thin aluminum fins create a wide contact area with airflow, accelerating the exchange of heat with the environment.
Fin-to-tube conduction: The tight contact between fins and flat tubes facilitates efficient conduction of thermal energy.
Refrigerant-side flow: Inside each flat tube, multiple microchannels distribute refrigerant evenly, minimizing pressure drops and ensuring consistent cooling or heating.
These innovations result in 20–40% higher energy efficiency, depending on the system and application.
