Finned Tube Heat Exchangers

Our range of finned tube heat exchangers offers an ideal solution where low density, low heat transfer fluids are to be exchanged with a high heat capacity streams. In these exchangers the tubing is formed in a single, continuous length which is bent into a zigzagged or serpentine shape & then inserted through elongated slots formed in a series of fin plates.

An Finned Tube heat exchanger, is simply a pressure vessel which cools a circulating fluid within finned tubes by forcing ambient air over the exterior of the tubes. Also, This is known as device for rejecting heat from a fluid directly to ambient air. The main advantage of an FTHE is that it does not require water, which means the plants requiring large cooling capacities are need not be located near a supply of cooling water.

Purpose of Finned Tube Heat Exchangers :

1. Finned Tube heat exchangers are generally used where a process system generates heat which must be removed, but for which there is no local use. Also This is One of the simplest ways is to use the ambient air.

2. They are usually used when the outlet temperature is more than about 20 deg. F above the maximum expected ambient air temperature. They can be used with closer approach temperatures, but often become expensive compared to a combination of a cooling tower and a water-cooled exchangers.

3. The most important thing is, They are a "green" solution as compared to cooling towers and shell and tube heat exchangers because they do not require an auxiliary water supply (water lost due to drift and evaporation, plus no water treatment chemicals are required).
