Spiral Finned Tube Heat Exchanger

Fins are basically external surfaces on tube for increasing the surface area of the bare tube, resulting in a compact Heat Exchanger. The method of attaching the fins over tube is of prime importance, since even a slightest air gap between the tube and fins will defeat the whole purpose of fins over the tube.A spiral tube heat exchanger is a coil assembly fitted in a compact shell that optimizes heat transfer efficiency and space. Every Sentry spiral assembly has welded tube to manifold joints for durability and strength. The coil assembly is welded to a head and fitted in a compact shell.Finned tubes are the main components of heat exchangers. They are a series of tubes where fins have been added on the outside to increase the contact area with the outside fluid, to exchange heat and between the fluid inside the tube and the fluid outside the tube.
