Home \ Products \ Finned Tube Heat Exchangers

Finned Tube Heat Exchangers consist of a shell & finned tubes assembly. Finned Tube Heat Exchangers consists of Fins on or in tubes which increase the effective surface area of heat exchanger.

Finned tubes are used when the heat transfer coefficient on the outside of the tubes is appreciably lower than that on the inside; as in heat transfer from a liquid to a gas, vapour to a gas, such as steam to air heat exchanger, fluid to air heat exchanger. When an extended surface is needed on only one fluid side (such as in a gas to liquid exchanger) or when the operating pressure needs to be contained on one fluid side, a finned tube heat exchanger may be selected.

Vikrant Heat Exchangers Pvt. Ltd. has established a Spiral Finning Machine and Press Machine for Finning process.

The advantage of finned tubes is that by increasing overall heat transfer rate, the total number of tubes required for a given application is reduced, thereby also reducing overall equipment size and decreasing the cost of the project. In many application cases, one finned tube replaces six or more bare tubes at less than 1/3 the cost and 1/4 the volume.
