Trane, York and Carrier Chillers “COI1684E” Microchannel Condenser Coil

Microchannel coils are an all aluminum coil that have been successfully used in the automotive industry for many years, and is now being applied in the HVAC industry. Microchannel technology is an entirely new condenser coil design for air cooled (direct expansion) equipment. The all aluminum construction of microchannel coils consist of tubes, headers and ribbon fins that are all brazed together in a controlled air automated brazing furnace. This automated brazing process dramatically reduces the number of brazed joints that are typically seen with the traditional tube and fin condenser coils. Their compact all aluminum construction also helps to reduce the unit’s weight improves recyclability and minimizes galvanic corrosion.
