What is the difference between Plate and Fin and Serpentine Evaporators?
Serpentine Evaporators have one flat continuous tube with many passes. They curve back and forth like a snake the entire length of the evaporator. Plate and Fin evaporators have numerous plates that are separated by fins. The plates run the entire width of the evaporator and will be grouped in 3, 4 or 5 plates and are internally separated by baffles. The plates will have several small passes much like the serpentine. Plate and fin evaporators are the most efficient cores offered today.
