Detailed Product Description

HEAT EXCHANGER

AI heat exchangers are required in various industries. These are used to exchange heat between two mediums (Hot and Cold) e.g. compressed air to water, freon to water , hydraulic oils to water, air to steam, water to steam, air to air etc. Heat exchangers are also used in plastic/ bakelite moulding machines , compressed air systems for diesel generating sets, refrigeration & air conditioning , hydraulic & other oils, water chilling, sugar industries etc.Shell and Tube (with and without fins) and plate type, these systems are supplied by Advance International fabricated as per various international and indian standards. They are suitable for closed circuit cooling or electrical equipment using demineralised water and for cooling water soluble oil solutions in quenching tanks.

The shell side usually contains the process fluid and the tube side water from the town mains or a cooling tower, or an ethylene glycol solution from a chiller unit. In certain circumstances this flow arrangement can be reversed , but please consult us first.


TYPES OF HEAT EXCHANGERS

Shell and Tube Heat Exchangers:
Highly efficient designs, with shell diameters ranging from 4" to 50" (100 mm to 1250 mm) produce heat transfer rates up to 300,000 btu/hr. Flow rate are 25 m3/hr to 5000 m3/hr and pressure up to 200 kg/cm2

Heliflow Heat Exchanger Coil Type : It is a unique type of shell and tube heat exchanger. The tubes in the Heliflow are arranged in parallel , starting with an inlet manifold on one end , and terminating at an outlet manifold on the opposite end. The tube bundled is wound into a helical pattern. This coiled construction creates a spiral flow path for the fluid inside the coil. Each tube is in close contact with the tube above and below it. The coiled tube bundle is fit into a two pieces casing. When the casing is tightened , it is designed to slightly compress the tubes. Beacuse of the tight fit the shell side fluid is forced to circulate in a spiral pattern which is created by the open spaces between the coils.

Tube in Tube Heat Exchangers (Twin Tubes) A family of coiled , concentric tube heat exchangers, capable of handling pressures up to 200 kg/cm2 inner tube and 100 kg/cm2 outer tube. With their long single chamber flow path and high effectiveness, these heat exchangers are an ideal choice for sample cooling or vapor condensation.

Plate Type Heat Exchangers A plate heat exchanger consist of number of corrugated plates with gaskets placed in grooves along the edge. The adjacent plates come into contact with each other where the ridges meet. During assembly, the channel plates are pressed together in a frame to form a tight and efficient heat exchanger. By combining plates with different angles in the same plate pack, the optimum solution for any heat exchanger can be found.
