  • Refrigerated Air Dryers

    Moisture can damage an air compressor by running through the system’s hoses. Fortunately, there are refrigerated air dryers that serve to remove moisture from compressed air systems. In order to maintain these units, it is necessary to install an appropriately sized refrigerated air dryer.

    A common entry point for moisture tends to be the air compressor’s inlet air filter. Standard air compressors can convert up to seven cubic feet of air to 100 psig per single cubic foot, compressing water vapor within the air to that size.
    Water that becomes contained within compressed air comes in different forms, including mist, vapor, gas or liquid. A general purpose filter may be used with a compressed air system to remove liquid water, with remaining water that is either mist or vapor removed by the refrigerated air dryer.

    Refrigerated air dryers can also prevent contamination on equipment located downstream from the air compressor. Water contamination can cause moving parts to fail, reducing the holding capacity of airborne moisture by fifty percent when the temperature drops below fifty degrees, leading to costly repairs.

    The process the refrigerated air dryer goes through begins with the use of an air to air heat exchanger, which cools the compressed air. The heat exchanger then condenses moisture by small amounts, cooling incoming air and sending it to an air-to-refrigerant exchanger that cools it even further via liquid refrigerant. Remaining moisture is condensed into a liquid that is drained from the system. The air is then finally heated inside a heat exchanger to prevent the hose’s pipe from sweating.

    When searching for the perfect refrigerated air dryer, keep the pressure dew point in mind. The pressure dew point is the temperature required in order for water vapor or mist to condense into liquid. The most often used pressure dew point class is Class 4. To determine the pressure dew point class of your unit, as well as temperature requirements, have a test of equipment performed.

  • Advantages of Centrifugal Air Compressors

    When choosing an air compressor, make sure to pick one that is powerful enough to meet your needs or those of your business. Take into consideration an air compressor’s airflow and pressure when comparing compressors.

    There are three main types of air compressors: rotary screw, reciprocating and centrifugal, or dynamic, compressors. Screw and reciprocating compressors are positive displacement machines. Reciprocating compressors use a piston within a cylinder to increase the pressure of the air by reducing volume, while screw compressors use intermeshing screws that force air into a smaller and smaller space.

    Unlike rotary and reciprocating air compressors, a centrifugal air compressor is a dynamic system. A
    dynamic compressor increases air pressure using impellers – rotating disks - as well as a diffuser to convert velocity energy to pressure energy. It has the distinct advantage of being an oil-free air compressing system.

    Progressive stages are used to increase the pressurization of the air to the desired level, driven by an electric motor or a steam or gas turbine. Because centrifugal compressors compress air in stages, the air being compressed stays cooler and the air compressor is more efficient, both mechanically and in terms of the energy being used.

    Centrifugal air compressors usually operate at a high minimum speed. They are also capable of running continuously for long periods of time. They are often found in manufacturing plants, automobiles, and in gas, oil and refining industries. These compressors can also handle large flow rates, and these kinds of compressor can be some of the most efficient and consistent air compressors available. Centrifugal air compressors are often very compact as well.

    Centrifugal air compressor systems are a great fit for industrial settings, as they produce a constant flow of high-pressured air to meet high demands. The rotating impeller system means that centrifugal air compressors are able to provide continuous air flow. Other benefits are that centrifugal compressors provide oil-free compressed air, and because of their few wearing parts tend to be very low maintenance as well. Centrifugal air compressor systems are also usually very compact.

    Among the many benefits of a centrifugal air compressor are its simple design, its ability to produce oil-free air for sensitive applications such as the food and beverage industry, and its ability to produce high volumes of air. Although centrifugal compressors often have a high initial cost, this is usually compensated for by their long and relatively low-maintenance life.

  • An Introduction to Industrial Air Compressors

    Industrial air compressors are heavy duty machines that are used by a variety of industries to supply power to run tools and machinery. They feature an airend that compresses air, and this can be used to supply the energy that is needed to move machinery such as construction or fabrication equipment. Buyers need to be aware of several issues that are associated with these machines, and this ensures that they will purchase the proper machines for their needs.

    Businesses often choose to power machinery and tools with compressed air. This offers a number of benefits from other choices, and industrial compressors can supply equipment and machinery with a steady supply of air power.

    Consumers should be sure they purchase the right product for their needs, and there are several things to keep in mind before making a purchase. The primary component that is used to buy an industrial air compressor is the amount of air that is needed to run machinery or other tools. Compressors are variable in the amount of air that they can supply, and buyers need to research the needs of their machinery before they make a purchase.

    There are also several different products on the market, and they are known for their differences in the way they compress air. Industrial rotary screw compressors are one of the most common types, and they feature energy efficiency, low maintenance and low noise. Rotary lobe blowers are another option, and these machines are best for air knives, waste water treatment and pneumatic conveying. Portable compressors are the machine of choice for those in the construction industry. Most of these are affixed to a trailer and are designed to be towed behind a vehicle.

    There are a few maintenance tasks that are essential for ensuring an industrial air compressor lasts for as long as possible. The tanks that are used to hold air should be drained on a regular basis. There is a lot of water that can accumulate in these tanks, and draining will ensure the tank lasts. Another issue has to do with filters, and these should be changed on a regular basis. This prevents dirt and other debris from ruining the parts that are used by the machine to compress the air.
