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. we design & fabricate shell & tube type of heat exchangers in stainless steel & carbon steel. Exchangers are designed as per asme & tema standards. heat exchangers may be classified as below evaporators condensors after coolers oil coolers inter coolers special purpose heat exchangers custom designed heat exchangers capacity of exchnger designed is as per clients requirement. Shell dia varies from 3" to 125", while tube length from 3' to 40'. Tubes provided are plain ot finned or u-tube. Material for tube is ss, cs, copper various types of mediums of heat exchanger are. water to water water to oil water to gas water to air water to refrigerant oil to refrigerant brine to refrigerant
