As Western Australia’s largest independent provider of air compressors, compressor products and services, Cleveland Compressed Air Services in Perth is able to provide our customers with the right screw compressors for their needs, taking into consideration their process requirements.
A screw compressor is a positive displacement rotary compressor, with two screw elements that are under continuous rotation. Due to the continuous rotation, there is very little pulsation of flow, which gives it a significant advantage over piston compressors.Read more
As those who work in industries that require the use of compressed air know, it is very important not to get excessive water trapped in the air, whether in the vapour or liquid phase. Compressed air contains not just water droplets and vapour but also debris, oil, and other foreign matter. If there is too much water vapour in the compressed air, this could cause a number of operational problems that range from corrosion and rust in pipelines to fouling of processes and frozen external airlines. Compressed air dryers are mechanisms that remove water vapour from compressed air. There are three common types of compressed air dryers: refrigerated compressed air dryers, membrane compressed air dryers and desiccant compressed air dryers. Refrigerated Compressed Air Dryers These dryers operate via the use of air-to-air and air-to-refrigerator heat exchanges. Incoming compressed air is cooled by the air-to-air exchange, as the outgoing cool and dry air reduce the temperature of the warmer incoming air. This incoming air then goes into the air-to-refrigerator exchanger, where the temperature is reduced through the use of liquid refrigerant to 3 degrees Celsius. This condenses any moisture that is present in liquid water, which subsequently drains off, and the cool outgoing air starts off the process all over again. Membrane Compressed Air Dryers Membrane dryers remove both contaminants and water vapour, as they are a filtration system that works with existing compressed air systems. Humid compressed air passes through a bundle of hollow fibres made of a membrane designed specifically to attract water vapour. Moisture is diffused through to the outside of the thin membrane where it is removed, and the higher the pressure in the compressed air system, then the better the membrane dryer will perform. This is a space saving system and does not use refrigerating agents in its operation. Desiccant Compressed Air Dryers As the name suggests, this type of compressed air dryer works by moving compressed air through a compartment that is filled with desiccants. Desiccants are materials with natural moisture absorbing properties. A desiccant compressed air dryer or regenerative dryer as it is also known usually has two identical desiccant chambers. The unit will automatically use one compartment to dry out compressed air while the other compartment, which is also filled with desiccant, is being regenerated. The use of the two compartments alternate automatically, ensuring a constant supply of dry compressed air, and because it self-regenerates, it also allows for easy maintenance of the unit. The regeneration can be done utilizing heat, compressed air, vacuum or a combination of these technologies.FIND OUT MORE
When it comes to the types of air compressors that are available on the market, there are as many kinds as there are uses for an air compressor. The choice of which air compressor is right for you largely depends on the industry that it is being used in, whether it’s a compact, relatively silent scroll air compressor for the workshop you’re after, or the centrifugal, which is used in large industrial facilities, petrochemical and utilities. Here at Cleveland Compressed Air Services, our wide selection of quality air compressors include: Oil Lubricated Compressors Boge Screw Compressors SolidAir Screw Compressors Boge Piston Compressors Oil Free Compressors Boge Piston Compressors Boge Screw Compressors Cameron Turbo Compressors LENTO Water Injected Screw Compressors High Pressure Compressors Cameron High Pressure Compressors Boge Piston Compressors Piston (also called reciprocating) compressors and screw compressors are the most commonly used types today, and these come in oil lubricated and oil free models. The benefits of oil lubricated compressors include durability, capability to work in extreme environments, longer life spans and better protection against interior rust; however, they do have what is known as “oil carryover”, where a portion of the lubricant comes out with the compressed air. Also, oil lubricated models require re-oiling, oil changes and are heavier. For industries where the air that comes out needs to be completely oil free, oil free compressors are used. These compressors are more expensive to procure and do require more energy to produce the same amount of air; however, the lower maintenance of filtration and no oil change requirement do offset some of the costs. The oil free screw compressors also have a limited life and drop in efficiency overtime owing to the Teflon coating required on the rotors for self-lubrication. Water injected screw compressors do not suffer from the same problem, as water is a very good replacement for lubricating oil. Oil free compressors are also noisier but water lubricated machines have a lower noise output due to the dampening effect of water. Piston compressors, which start up quickly and can be left idle for long periods of time, are usually used in smaller factories and workshops with some use in specialised high pressure applications. Small piston compressors are easy to maintain and cheaper than many of their counterparts, the bigger range being very expensive to maintain and operate. Screw compressors, on the other hand, are used in situations where there is a larger air demand. They are known for their durability, consistently high output and acceptable operating volume level. Although they are generally more expensive than piston compressors, screw compressors do use less energy, are more reliable and, if properly maintained, can be left to run constantly. Centrifugal compressors are dynamic in nature and, therefore, are continuous flow units that are able to cater for large flow rate requirements in oil free and plant air applications. The centrifugal technology was originally limited to low pressure applications but these days medium to high pressure ranges are also catered for. The advantages of going with centrifugal compressors include oil free air production, low specific energy requirement, low maintenance and high reliability. The versatility of air compressors, and the high quality of our compressors in particular, make them especially reliable pieces of equipment that can be used in a variety of industries. These include: Heavy industry Medical Mining Oil and gas Workshop Food and Beverage Of course, these are only some of the uses of air compressors, which have gone from being staple pieces of equipment in power stations, oil and gas rigs, and manufacturing plants to home workshops and garages.FIND OUT MORE

At Cleveland Compressors, we are proud to offer a complete range of compressed air dryers from Parker Domnick Hunter. The range is divided into three types of compressed air dryers, namely: Refrigerated air dryers Desiccant air dryers Membrane dryers Not all compressed air dryers are created equal. Many manufacturers offer products for the filtration and purification of contaminated compressed air that have been selected based only upon their initial purchase cost, with little or no regard for the air quality they provide, the cost of operation throughout their life or indeed their environmental impact. Here at Cleveland Compressors, we believe that compressed air dryers should always deliver uncompromising performance and reliability while providing the right balance of air quality with the lowest cost of operation, and we are pleased to confirm that all of our products have been selected with this in mind. Domnick Hunter Refrigerated Air Dryers What is refrigeration drying? The use of refrigeration drying for compressed air treatment has been tested and proven for many industrial applications. Dewpoints of 3°C to 10°C have been found to be suitable for many indoor applications, where a general removal of bulk water and some vapour is sufficient for the end user’s process. Refrigerated air dryers can be used at low pressures as well as high pressures, and use no processed compressed air during the air treatment. They have also undergone many improvements to make them more energy efficient without sacrificing the quality of the air provided. Refrigerated air dryers use a set of heat exchangers or a single heat exchanger (with chambers) first to pre-cool the air; second, to refrigerate the air to condense out moisture vapour; and last, to re-heat the air to prevent pipe sweating downstream. Our refrigerated air dryers: Parker Hiross Starlette Plus Dryers (Up to 360 M3/H) Domnick Hunter Polestar Smart Refrigerated Air Dryers (450-10,800 M3/H) Domnick Hunter Polestar Smart High Pressure Dryers (180-7200 M3/H) Domnick Hunter Desiccant Air Dryers What is adsorption drying? Drying compressed air through adsorption represents a purely physical process in which water vapour (adsorbate) is bound to the drying medium (adsorbent) through binding forces of molecular adhesion. Adsorbents are solids in spherical and granular form that are permeated by an array of pores. Because water vapour is deposited onto the internal and external surface of the adsorption medium without the formation of chemical compounds taking place, the adsorption medium does not have to be replenished but only periodically regenerated. There are several types of adsorption desiccant air dryers, including heatless desiccant air dryers, externally heated desiccant air dryers, blower purge desiccant air dryers and vacuum assisted heatless desiccant air dryers. Cleveland Compressors deals in three types of desiccant dryers based on their application: modular, point of use and twin tower. Our modular desiccant dryers: Domnick Hunter modular desiccant air dryers (heatless, heated, blower purge and vacuum assist zero purge) Domnick Hunter Zander desiccant air dryers (4 SCFM and larger) Our point of use desiccant dryers: The FDD desiccant dryer series Our twin tower desiccant dryers: The AIRTEK series (heatless, heated, blower purge and high pressure) BALSTON Regenerative PSA desiccant air dryers ZANDER twin tower desiccant dryers (heatless, heated, blower purge) Membrane Dryers Membrane material that is selectively permeable to water vapour is an excellent medium for producing dry air from standard compressed air. Water vapour from the compressed air supply passes through the hollow fibres of the membrane. At the same time, a small portion of the dry air product is redirected along the length of the fibres to sweep out the water vapour-laden air that has permeated the membrane. The moisture-laden sweep gas is then vented to the atmosphere, and clean, dry air is supplied to the application.
