steam coils represent the best choice for preventing condensate from freezing, they are recommended for extremely low air temperatures. The benefits of this vertical tube installation design are related to the geometry that promotes the continuous purging of noncondensable gases from the first row of tubes and the flowing of the condensed water to the condensate main drain separately at each row. With this design the steam is fed in series to each row further enhancing the prevention of airbinding in the first row, typically the air in contact with the second row will be above freezing and not be a cause for condensate freezing concerns. Thermofin has also developed other designs that are the result of combining the aforementioned concepts. Thermofin’s strength is the development of steam coil heat exchanger solutions that match and exceed the unique needs of your operation.
