Heat Exchanger play major role in any Plant. They are major source of energy transfer. A heat exchanger is a device used for efficient heat transfer from one fluid to another. These fluids are separated by a solid wall, so they are in indirect contact with each other. They are widely used in Refrigeration, Air Conditioning, Food Processing, Textile Industry, Chemical Plants, Petrochemical Plants, Steel Plants, Petroleum Refineries, Power Plants and Natural Gas Processing. Hence they are needed to be precisely designed & fabricated.
