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.
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.
PNEUDRI modular compressed air dryers a dedicated solution for every application By combining the proven benefits of desiccant drying with modern design, Parker domnick hunter has produced an extremely compact and reliable system to totally dry and clean compressed air. The Parker domnick hunter PNEUDRI ranges of heatless and heat regenerative dryers have proven to be the ideal solution for many thousands of compressed air users worldwide in a wide variety of industries.
PNEUDRI - How It Works 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 air contacts the adsorbent material, water vapour transfers from the wet air to the dry desiccant, however, adsorbent materials have a fixed adsorption capacity and once this capacity is reached, they must be regenerated or replaced.
PNEUDRI - The world's most advanced modular drying system With the proven benefit of advanced aluminium forming technology, Parker domnick hunter has developed a twin tower desiccant dryer that is typically 60% of the size and weight of conventional designs. These advanced desiccant dryers include ranges of heatless and heat-regenerative PNEUDRI dryers which provide one of the most simple and cost effective compressed air drying solutions.
PNEUDRI - four key features guarantee air quality OIL-X EVOLUTION filtration Adsorption dryers are designed for the removal of water vapour and not liquid water, water aerosols, oil, particulates or micro-organisms. Only by using Parker domnick hunter OIL-X EVOLUTION pre and after filtration can the removal of these contaminants be assured and air quality in accordance with all editions of ISO8573-1 be guaranteed.
Selecting the right dryer for your compressed air system To achieve the degree of air quality specified by ISO8573-1:2010, a careful approach to system design, commissioning and operation must be adopted. Parker domnick hunter recommends that compressed air is treated: • Prior to entry into the distribution system • At critical usage points and applications This ensures that contamination already in the distribution system is removed.
What size PNEUDRI do I require? Dryer Selection To correctly select a dryer model, the flow rate of the dryer must be adjusted for the minimum operating pressure and maximum operational temperature of the system. If the dewpoint required is different to the standard dewpoint of the dryer then the flow rate must also be adjusted for the required outlet dewpoint. Selection Example Selecting a dryer for a compressor producing at full load 1500 m³/hr at 8.

Improving manufacturing efficiency Every manufacturing organisation strives to improve its operational efficiency, especially in terms of energy consumption and environmental impact. Heatless adsorption dryers use clean, dry process air for regeneration, but in real terms, this means that not all of the compressed air generated is available for manufacturing processes.

Saving energy with the dewpoint dependent switching (DDS) energy management system 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 at full capacity all of the time, for example during shift work and periods of low demand.
Compressed air for hazardous environments Oil & Gas Drilling and Production Installations can be some of the most inhospitable working areas known to man. Apart from potentially explosive and corrosive areas, ambient temperatures can vary from -20°C to 50°C with wind speeds of up to 80mph and the constant battering from high waves, an oil rig is a demanding place for man or machine.
