Air cooled compressor is a compressor cooled by atmospheric air circulated around the cylinders or casing. An air-cooled compressor relies on ambient air blowing over the cylinder head to cool the compressor. To aid in cooling, the cylinder and intercooler have cooling fins mounted on them. Air-cooled compressor is a kind of piston compressor.
Air cooled generators are available with open ventilated and with a closed-air circuit or totally enclosed water to air-cooled circuits. Generators with open-air circuit cooling are low-cost and have no need for additional cooling. Generators with closed-air circuit cooling are built for capacities up to 480 MVA. These machines are well suited for use with single shaft combined-cycle plants where the gas turbine and the steam turbine drive the same generator.
Air-Cooled Heat Exchangers are an all-aluminum bar & plate design featuring a wide variety of thermally efficient internal and external fin patterns. An air-cooled heat exchanger is simply a product, which cools a circulating fluid within finned tubes by forcing ambient air over the exterior of the tubes. Air-cooled heat exchangers are commonly used in petrochemical facilities to cool process fluids. These heat exchangers have an integral electric motor or fluid powered fan for cooling/heat removal of media. Some air-cooled heat exchangers are frequently used in process plants as condensers and coolers.
Air cooled power tubes consist of socket and filter. These power tube equipment is done with squirrel cage blowers. It requires air flow when operated at higher altitudes because of decreased density of the cooling air. Tube data sheet gives cooling system correction information. It has an air interlock switch on the cooling fan to prevent voltages to the tube unless cooling air is flowing.
