In a refrigeration system, a tube-and-fin heat exchanger has spaced fins that extend to an outer periphery of the heat exchanger and has smaller embedded fins in between or in a spaced relationship with each of the other fins. The embedded fins do not extend all the way to the outer periphery of the fins along the airside directions but have a shorter outer periphery such that there is an offset distance. Because of the offset distance, there is space that continues to provide room for fluid movement without fouling of the face of the heat exchanger and that provides an expected appearance while still having the benefit of additional fins elements further inside of the heat exchanger. Other exchangers and condensers are included.
