make no mistake, a cooler alone does not yield high quality compressed air. cooling condenses lots of water. post-cooling, all that water is still in the air line! removing the liquid requires a moisture separator and a drain valve. in small air systems (<20 hp) it’s common to see the receiver tank used to separate and collect liquids.
the aftercooler is just a simple cooler that goes between the compressor outlet and the tank. it’s goal is to cool the air before it gets to the tank, which causes it to drop a bunch of the moisture (not all, you still want a dryer or other moisture reducer if you need really dry air for applications like painting).
aftercoolers are heat exchangers for cooling the discharge from a air compressor. they use either air or water and are an effective means of removing moisture from compressed air. aftercoolers reduce the amount of water vapor in a compressed air system by condensing the water vapor into liquid form. aftercoolers combined with a seperator are an excellent way to reduce moisture in a compressed air
an aftercooler reduces the temperature and water content of the compressed air. all compressed air systems should have an efficient aftercooler installed immediately after the compressor to remove condensed water from the air distribution system.
advantages of after cooler in air compressor ? to reduce final discharge air temperature thus air bottle size can be reduced. to reduce air volume after it has been compressed to the final pressure. so greater amount of air could be stored in air bottle. increase volumetric efficiency how to start the air compressor manually on ships ?
what is an aftercooler? an aftercooler is a mechanical cooling unit that operates on the principles of heat exchange between two mediums usually water and air. aftercooler units can be used to attain temperatures between 5-20°f immediately after compressed air is released from the compression unit. how does an aftercooler work?
we are using coolers in compressor cycle. because it will reduce ‘power required to drive the compressor’. we know how the compressor works. compressor rise the pressure of the air or gas. in single stage compression there is no coolers needed. because air
an aftercooler is a heat exchanger used to cool compressed air and minimize moisture within the system. reduced compressed air temperatures cause water and oil droplets to precipitate out of the air, and these liquid contaminants are typically collected and drained off with a moisture separation device and drain trap (either mechanical or timed).
>can provide good lubrication of the compressor piston aftercooler >fitted at the final stage discharge side >increase volumetric efficiency >reduce final discharge air temperature to room temperature >help to reduce air-bottle size >moisture separation is easier through after cooler drain
an intercooler is a mechanical device used to cool a gas after compression. compressing a gas increases its internal energy which in turn raises its temperature and decreases its density. an intercooler typically takes the form of a heat exchanger that removes waste heat in a gas compressor.
both inter-cooler and after-cooler serve the same purpose cooling the air after coming from air compressor/turbocharge/supercharger and before entering the engine. this is done because, cold air has more density thereby more oxygen henceforth more combustion giving rise to more power. both are same devices, only nomenclature is different.
ambient atmospheric air is heated by passing it across the system’s aftercooler and lubricant cooler, where it extracts heat from both the compressed air and the lubricant that is used to lubricate and cool the compressor. this is relatively low temperature (under 100°f) heat and is
moreover, a cooler in the recycle line may have to be considered, to suitably control the suction temperature and thereby prevent the compressor from going into surge. the line-up and tie-in point of the recycle line on the suction side of the compressor shall be at the upstream of the suction scrubber in order to prevent liquid from entering the compressor.
an aftercooler is a heat exchanger that cools the hot compressed air to precipitate the water that otherwise would condensate in the pipe system. it is water-cooled or air-cooled , is generally equipped with a water separator with automatic drainage and should be placed close to the compressor.
reduce the work of compression and increase efficiency. they are normally water-cooled. • after coolers: the objective is to remove the moisture in the air by reducing the tempera-ture in a water-cooled heat exchanger. • air-dryers: the remaining traces of moisture after after-cooler are removed using air dry-
the more compressed air is cooled inside a compressor's inter-cooler and aftercooler, the more energy-efficient the compressor will be and the more the water vapor will be condensed. a water-cooled compressor installation puts little demand on the compressor room ventilation system, as the cooling water contains, in the form of heat , approximately 90% of the energy taken up by the electric motor .
i also explained that most of the water is supposed to be removed in the compressor aftercooler, separator and drain, about 75%, leaving the last 25% to the dryer. just 25 yards to a touchdown, one good run and you’re in. however, if the after-cooler is fouled, or the drain is not functioning, the load on the dryer can more than double.
the superior design of the aftercoolers ensures that the compressed air will be cooled to the closest approach temperature above the cooling media temperature. this outstanding heat exchanger performance, combined with the high efficiency of a separator, ensures the maximum removal of moisture from the compressed air.
primary receiver - located near the compressor, after the after-cooler but before filtration and drying equipment secondary receivers - located close to points of larger intermittent air consumption the maximum capacity of the compressor in a well designed systems always exceed the maximum mean air consumption of the system (maximum mean air consumption is the mean air consumption over some
the term aftercooler refers to the charge air being cooled after being compressed in the compressor. increasing demand for improvements in fuel economy and exhaust emissions has made the charge air cooler an important component of most modern turbocharged engines.
an after cooler is basically a car radiator that the air gets piped through to chill it, condensing out the water vapor. in fact, if you look online you can actually find plans to turn the top half of your garage beer fridge into an air cooler with not much more than some fittings and copper tubing. periodic maintenance. the biggest periodic maintenance task to do regularly is drain the compressor
mellcon compressed air aftercoolers are high performance shell and tube heat exchangers coolers connected to a moisture separator and a drain trap. all after coolers are individually stage wise inspected as per is-2825/asme/tema standards. the tubes used are high quality copper / cupro nickel/ss/ carbon steel as per user's requirement.
from the scrubber, the gas is taken to the compressor unit (s), where it is compressed. at the compressor station discharge (or between compressor units, in the case of series arrangement) the gas is cooled, typically with an air cooler, and then passed through a
discharge coolers. a discharge cooler (after cooler) is required if the temperature of the gas at the compressor discharge exceeds that required for the next step in the process. suction scrubbers. erosion of compressor components can be caused by ingestion of excessive liquid.
