Lambda In-Row CW II features microchannel cooling coils with a remarkably high heat transfer performance and quite low air resistance.
Microchannel tubes brazed together with louvered fins using a controlled atmosphere brazing furnace have a perfect and permanent contact between tubes and fins, assuring an efficient heat transfer. The small hydraulic diameter of the microchannel tubes and high efficiency of louvered fins further improves the heat transfer performance. The flat geometry of microchannel tubes results in reduced aerodynamic drag while minimizing the air shadow on the back side of the tube. The end effect is the reduced airside pressure drop and lower required fan power.
Aluminium microchannel coils are lightweight, robust and have significantly lower internal volume, resulting in lower unit weight and simplified design.
