But to understand why are products are amazing you have to understand what they do, how they work.
Clean dry and compressed air is a prerequisite for almost every industrial application that involves compressed air. Industries utilize compressed air to move conveyors, operate critical instruments, power pneumatic tools and automate equipments. The productivity and profitability of any industry depends upon the smooth running of its machinery and minimum expenditure incurred over repairs and maintenance of equipments. Smooth functionality of its machinery is highly dependent on compressed, clean and dry air quality. Therefore in order to achieve the desired results most industries make use of compressed air dryers.
The air quality required for smoother operations of compressed air systems should be free of contamination. The most predominant forms of contamination are water and oil. Water vapor present in the air condenses when it is cooled and compressed, this condensation leads to air contamination which are responsible for adversely affecting the quality of air resulting in corrosion, clogging of instruments, scaling and jamming of valves. The role of Compressed air dryer is to effectively eradicate moisture, lubricants, and air impurities that are responsible for contaminating compressed air. This results in improved efficiency and reduction of operating costs.
The process of drying compressed air by compressed air dryers requires different stages and involves various components such as compressor, after cooler, separator, pre-filter, dryer, after- filter and finally the receiver. The role of the compressor is to compress air to a required pressure level. The after-cooler acts as a heat exchanger where the moisture is condensed into liquids. The separator removes the entrained liquids which are a result of the after cooler process. The pre-filter plays the role of removing fine oil and water mist aerosols. The remaining water vapor from the compressed air is finally done away with by the dryer. The after-filter removes and filters the desiccant dust carried over from the dryer and finally the receiver that stores the clean and dry compressed air.
Compressed air dryers are of different types, refrigeration dryers, Desiccant dryers, and Membrane dryer. All of these dryers are known to produce different dew points. Hence care should be taken while choosing the right kind of compressed air dryer. Tube-in-tube refrigeration dryers are designed to produce dew points of 35 or 50 degrees Fahrenheit by cooling a mass of aluminum granules. The Water chiller refrigeration dryers make use of a mass of water for cooling and are made to produce dew points between 40 to 50 degrees Fahrenheit. The desiccant dryers use a cylinder that is filled with desiccant material like silica gel; the compressed air is pressed through this cylinder. This process brings down the dew point of water in the air to minus 40 degrees Celsius. The membrane dryers are devices that use dehumidification membrane that extracts water vapor from the compressed air. Membrane dryers are particularly used in pneumatic equipments.
In order to meet the specific requirements of Compressed Air Dryers systems, there are a number of reputed companies that produce a wide range of Compressed Air Dryers Accessories such as automatic drain valves, compressed air filters, mechanical separators, mist eliminators and flow flex meters. These companies provide the required solutions and services for all types of compressed air dryer systems.
Compressed air has many functions in everyday life. It is used in industries that produce food and dairy products and for tools that spray paint, packing machines, pneumatic control systems and many more uses within different industries. Although compressed air has many uses such as in tools that may produce sparks, therefore it is much safer than other methods there is a downside. The compressed air can release small particles of hazardous chemicals, which can enter the blood stream and lungs, which in turn could cause fatalities. To avoid this Compressed air dryers are important in industries where compressed air is being used.
There are many different types of compressed air dryers. These include the twin tower dryer (also known as regens dryer and desiccant dryer); the Deliquesant dryer, the membrane dryer and most commonly used the refrigeration dryer. Each type of dryer has it’s place depending on which environment it is used in.
The refrigeration dryer is used in environments where air tools such as sand blasters, and pneumatic control systems are in place. Used with an air line filter it removes moisture as well as 70% of oil aerosols and any particles which are 1 micron or larger in size. When paint spraying, powder coating and packing machines are used, the refrigeration compressed air dryer along with an oil removal filter will remove moisture along with 99.9% of oil aerosols as well as particles 0.25 microns or larger. As compressed air is also used in the food and dairy industries, the refrigeration compressed air dryer also has its place here. Along with an oil removal filter and oil vapor absorber it removes moisture as well as 99.9% of oil aerosols, as well as larger oily vapors, oily smells and oily tastes. Not only this it also removes particles that are 0.25 microns or larger.
The refrigeration compressed air dryer works by using two heat exchangers. As well as this it also has a single heat exchanger. Combining both functions. The compressors in the refrigeration dryers are commonly used with a gas called R-134Q. The two heat exchangers let the cold air going out cool down the hot air coming in, this in turn reduced the size of the compressor needed. The increase of temperature of the outgoing air prevents re-condensation.
The deliquesant dryer controls the amount of moisture in the air; this is often referred to as the dew point. If the dew point gets too high then the moisture in the air will be too heavy to remain where it is so could at the least short out electrics and could cause electrocution. It can also cause high body temperatures, which in itself can cause problems. The deliquesant dryer is a tank that is filled with a salt, calcium chloride or urea. When the compressed air passes through the tank it turns the solid salt (or similar) to liquid that is then collected and can be drained off. The deliquesant compressed air dryer can be used in cement plants, sawmills and when portable blasting, and or coatings or being used. It can be used in cold temperatures or outdoors, as it does not need electricity to work.
The membrane compressed air dryer works by using hollow fiber membranes to collect the moisture. They work by acting as a conduit to transfer the water vapor and set as a barrier to separate the membranes from the humid air. A dry carrier gas is produced which purges the air and is continually vented from the shell of the dryer. The benefits of the membrane compressed air dryer is that it has no moving parts that may need replacing and that it is more environmentally friendly than other types of dryers as it has no moving parts, no electrical heating supply, chillers, moisture or drain systems which means that it needs a lot less maintenance.
You can purchase accessories for the condensed air dryers, these include filters which come in different particulate and coalescing types, this means you can customize your dryer to suit the environment for which it is to be used in. Electronic timed drainer valves, which can be adjusted to suit the user. Strainer ball valves, which allow the user to shut off the compressed air supply to isolate the mesh screen. Oil and water separators can be used to separate oily air system discharge.
However, when you have picked out the compressed air dryer you want and need, you will want to take a step back and consider how you are going to pay for it. You can use the best checking account you can find (you can find the best banks online) or you might want to consider putting it on a credit card if it is more expensive than you can afford to pay in full. Some companies will even let you put your new compressed air dryer on lay away so you can pay for it over time and ease the strain of the cost. With so many people losing their jobs and record numbers of people facing loan foreclosure, everyone is aware that money is tight for most people. Most companies are more than happy to work with you on paying for your new compressed air dryer.
Also, even before that when you are picking out which compressed air dryer you want to purchase there are many things to consider. What do you really need it to do? How good is the quality? Are you getting the best deal? Finally, what is the warranty and have there been problems with warranty complaints? If it breaks on you soon after you buy it you don?t want to have to run out and buy another while fronting the financial loss. Almost every product these days comes with some kind of warranty. Sometimes you can even buy an extended warranty to protect your investment longer. Make sure you know what your compressed air dryer?s warranty terms are before you buy? It just makes life simpler so you can enjoy your compressed air dryer without having to worry.
