We supply several types of air-cooled heat exchangers to meet your needs
Air cooled heat exchangers are commonly used in industrial applications where a reliable source of water is not available as a cooling medium. Even if water is available, in some cases, air cooled exchangers are favored for economic or operational reasons.
Air cooled heat exchangers are used throughout the entire oil and gas industry from upstream production to refineries and petrochemical plants, under conditions including high pressure and temperature, as well as corrosive fluids and environments. Common applications include gas re-injection, gas lift and pipeline applications, cooling and condensing of hydrocarbon gases, and cooling of machinery oil and heavy hydrocarbons.
The hot process fluid to be cooled flows through a tube while the cooling air flows across the outer surface to remove heat. The cooling air is propelled by fans in either a forced draft or induced draft configuration. Specially designed fins are attached to the outer surface of the tube to create a large surface area for more effective cooling. The heat transfer rate is a function of the fins’ surface area and the velocity of the air flow.
The mechanical design of the exchanger must accommodate the process conditions including pressure and temperature and, possibly, corrosivity, fouling and condensation
The key to quality and long service life is the proper selection of materials and fabrication technology, not the least of which is advanced welding capabilities.
