Heatless Modular Compressed Air Dryers ENGINEERING YOUR SUCCESS.

Compressed air contamination is a real problem for industry In today’s modern production facilities, the use of compressed air is often pivotal to manufacturing processes. Irrespective of whether the compressed air comes into direct contact with the product or is used to automate a process, provide motive power, or even to generate other gases on-site, a clean, dry, reliable compressed air supply is essential to maintain efficient and cost effective production. Parker provides complete compressed air treatment solutions to suit every industry, application & budget. The benefits of using Parker...

Compressed air dryers – The heart of the compressed air treatment solution At the heart of any compressed air treatment solution is the dryer, it’s purpose, to remove water vapour, stop condensation, corrosion and in the case of adsorption dryers, inhibit the growth of micro-organisms. Heatless adsorption dryers (also known as PSA dryers) are the simplest type of adsorption dryer available and have long been the dryer of choice for many industries and applications. They are simple, reliable and cost effective and for small to medium flow systems, often the only viable technology available. Additionally,...

Parker Heatless Modular Dryers Using advanced aluminium extrusions, Parker has developed a desiccant dryer ranges that are smaller, more compact and lightweight comparied to conventional fabricated steel designs. These advanced desiccant dryers include ranges of small flow, medium fow and large flow heatless modular dryers which provide one of the most simple and cost effective compressed air drying solutions. Engineers at Parker have developed each range using innovative aluminium forming technology, resulting in units that are smaller, more compact and lightweight compared to conventional welded...

Parker Heatless Modular Dryers - Four Key Features to Guarantee Air Quality OIL-X Filtration Adsorption dryers are designed only for the reduction of water vapour and not liquid water, liquid oil, water aerosols, oil aerosols, particulates or micro-organisms. Only by using Parker OIL-X pre and after filtration can the treatment of these contaminants be assured and air quality in accordance with all editions of ISO8573-1 be guaranteed. Modular aluminium design Aluminium extrusions are used throughout for drying chambers and distribution manifolds. This design not only alows the dryer to be smaller,...

Heatless Modular Dryer - Operation Adsorption dryers work on the principle of moisture always migrating to the driest medium possible. Therefore, water vapour is removed from compressed air by passing it over an adsorbent desiccant material. As the compressed air contacts the adsorbent material, water vapour transfers from the wet air to the dry desiccant material. Adsorbent materials have a fixed adsorption capacity and once this capacity is reached, they must be regenerated or replaced. Therefore, to provide a continuous supply of clean, dry compressed air, adsorbent dryers utilise two chambers...

Heatless Modular Operation - Regeneration Cycle At the start of the regeneration cycle, the exhaust valve of the dryer is closed and the off-line chamber is at full line pressure. The air in the off-line chamber has a dewpoint equal to the air leaving the dryer. The exhaust valve is then opened and the dry air within the chamber expands rapidly as it leaves the dryer via the exhaust silencer, forcing water to be removed from the desiccant material. Once the off-line chamber has depressurised, a continuous bleed of dried process air is directed into the off-line desiccant bed for regeneration...

Heatless Modular Dryers - EST & DS Energy Saving Technologies Proportional Energy Usage The Parker EST / DS - Energy Saving Technologies ensure the energy consumed by the dryer is directly proportional to the amount of water vapour present and not the dryers maximum rated capacity. AVERAGE MAXIMUM DAILY TEMPERATURE The energy required to regenerate the off-line desiccant bed in an absorption dryer is constant, and based upon the assumption that the dryer is operating at its full capacity and the desiccant bed requiring regeneration has been fully saturated. In reality, a dryer is rarely operating...

EST & DS Energy Saving Technologies Operation Parker CDAS / OFAS / FBP / MXS-DS / MXLE dryer ranges are all fitted as standard with either the EST or DS Energy Saving Technologies (optional for K-MT & KA-MT ranges). With these installed, the drying cycle remains unchanged, however as the drying chambers are about to change over, the EST / DS energy saving technology overrides normal operation to fully utilise the drying capacity of the on-line desiccant material. EST & DS Energy Saving Drying Cycle Extension At the end of the regeneration cycle, and prior to column changeover, the exhaust valve...

Dryer Positioning The preferred installation for any compressed air dryer is downstream of a wet air receiver as the air receiver not only stores compressed air, it actually reduces the temperature of the compressed air slightly and can help reduce “excessive peaks” in moisture loading should they inadvertently occur. Additional Energy Savings For installations where a Parker modular dryer is installed between the air compressor and the air reciever, an additional energy saving feature built into the controller can also be implemented. A Typical Installation In a typical installation, the compressor...
