Dual Turns Coil

The main feature of this design is merging the two active parts of the coil together and inside each other. Generally the two active coils lo-cated at the centre are designed as spirals (like helical coils) while the upper and lower parts that are neutral cooling coils are winded as off-set coil. Advantages of this kind of coil are high functional efficiency and more suitable water circulation. Most of coils manufactured by German Companies and some Turkish companies are placed in this category.
