pressure loss. Gas may be on tube or fin side. Special

materials may be used for temperature, pressure or

corrosion.

Application:

Fuel Cell, industrial Equipment, Pollution, Power Plants-

Combustion Energy Conservation.

Finned Tube Heat Exchanger consist of a shell & finned

tubes assembly. Fins are used to increase the effective

surface area of heat exchanger tubing. 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, vapor to a gas, such

as steam to air heat exchanger, thermic 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.

Applications of finned tube heat exchangers include

Steam air heater! steam radiator, Thermic fluid air heater

/ thermic fluid radiator, Hot water air heater! hot water

radiator, Air heater for fluid bed dryers, Air heater for

spray dryers, Air heater for flash dryers and Air heater for

dryers. These are manufactured using high grade carbon

steel, stainless steel, copper, brass and aluminum. Our

Finned Tube Heat exchanger are designed to meet the

specific duty condition, temperature and pressure of the

fluids.

Charge air coolers are specific heat exchangers that are used in

particularly stressful environments, such as on internal

combustion engines with turbochargers or superchargers. Charge

air coolers are located between the turbo charger and the engine

air inlet manifold. When the air is compressed by the

turbocharger or supercharger, it is also heated, which causes its

density to decrease. Cooling the combustion air by a charge air

cooler prior to sending it into the engine, the density of the air

increases which permits more air to enter the engine and

increases the power and efficiency of the engine.

Charge air coolers are basically manufactured in two types: "Air —

Air" (where the first and second fluid is air) and "Water — Air"

(where the primaryfluid is air and the secondaryfluid is water

Water-air heat exchangers where the primary fluid is air and the

secondary is water are manufactured in two main designs which

are the finned block and the shell and tube designs.

Sprey Type :

This type houses a set for spary nozzles which inject the water into

the air stream in the form of a fine atomized mist (by breaking the

water into fine particles we increase the surface area by multiple

folds for the same volume of water.) in this system, the water is in

direct contact with the airflow unlike the cellulose type systems,

when a single bank is provided (depending upon the efficiency

required) the spray in injected in the opposite direction of the
